These meters are capable of measuring the flow of a range of clean liquids such as fuels, fuel oils & lubricating liquids.The flowmeter is available with a pulse output only for safe or hazardous areas. The meter also has a flow rate register option with either RT40 (option E) for safe areas or an intrinsically safe RT12 (option I) for hazardous areas. Both these totalisers have pulse output capabilities of interfacing to most monitoring and controlinstrumentation. The RT12 instrument also has monitoring and control output options 4-20mA, scaled pulse and flowrate alarms.Both RT12 and RT40 options have multiple display units (kgs, Litres, lbs, Gal and m³) and can show instantaneous flow rate and total flow values1.2 Operating PrincipleThe Oval gear are positive displacement flowmeters where the passage of liquid causes two oval geared rotors to rotate within a precision measuring chamber and with each rotation a fixed volume of liquid is displaced passing through the meter. Magnets embedded within the rotors initiate a high resolution pulse train output. The pulse output can be wired directly to process control and monitoring equipment or can be used as an input to instruments supplied with or fitted directly to the meter.The benefits of this technology allow precise flow measurement and dispensing of most clean liquids irrespective of their conductivity, with other liquid characteristics having nil or minimal effect on meter performance. This metering technology does not require flow profile conditioning as required with alternative flow technologies making the installation relatively compact and low cost.OPERATION :Liquid travels around the crescentshaped chambers created by therotational movement of the rotorsliquid exits the measuring chamber liquid in transit flow liquid entering measuring chamberSpecifications 31.3 Specifications4 Installation2.0 Mechanical Installation Prior to installing the meter check :•The fluid is compatible with the meter materials of construction using appropriate information such as fluid compatibility charts and site experience.•The application and process conditions are compatible with the meter specifications. Minimum and maximum flows are within the meter specified range including any in-situ cleaning processes. Whenmetering viscous liquids the maximum allowable flow may need to be reduced to ensure the pressuredrop across the meter does not exceed 100 kPa (1 Barg, 15 PSIG).•The process temperature and pressure does not exceed meter ratings.•The meter is not exposed to process temperatures and pressures that will cause the liquid medium to gasify (flash) within the meter.2.0.1 Flow Conditioning and LocationsStrainer : It is recommended to INSTALL a 40mesh (350 micron) strainer immediately upstream of (prior to) the meter. Strainers are available from the factory.Flow conditioning : The flowmeter does not require any flow conditioning, therefore straight pipe runs before or after the meter are not required. If required, the pipe size about the meter can be altered to suit the installation.Locations : The flowmeter is preferred to be fitted upstream of any flow control and/or shut off valve, this prevents free discharge from the meter and minimizes the risk of drainage and air entrapment which can result in erroneous readings or damage the meter on start up.Process or safety critical meters should be installed in a by-pass section of pipe with isolation valves to enable the meter to be isolated and serviced as required. A by-pass installation also allows purging of the system during commissioning (see Commissioning).The meter must be appropriately rated and is typically located downstream (on the discharge side) of the pump.If mounted outdoors ensure a suitable watertight gland or plug is used to seal any open electrical entries. In humid environments take precautions to avoid condensation build up within the electrical and/or instrument enclosure. It is good wiring practice for conduits to be connected from the bottom of an entry port, in this way condensation will gravitate away from any terminal housing.Fluid state : Fluid entering the meter must remain a liquid at all times so protect the meter to avoid solidification or gelling of the metered medium. If meters are to be trace heated or jacketed in any way the maximum temperature rating of the meter must not be exceeded. Size the meter to avoid gasification of volatiles (flashing) within the liquid due to the pressure drop experienced within the system or within the meter.Hydraulic shock : If pressure surges or hydraulic shock of any kind is possible, the system upstream of the meter must be fitted with a surge suppressor or pressure relief valve to protect the meter from damage. High frequency flow pulsations can damage the meter. Such pulsations can be caused by the injection profile in diesel engines. Most pulsations are removed with the installation of a suitable pulsation dampener.Installation 5 2.1 Meter & totaliser orientationThe flowmeter MUST be mounted so that the rotor shafts are in a horizontal plane. This is achieved by mounting the meter so that the digital display is facing the user in a horizontal direction, it should never point towards the sky or towards the ground. If installed incorrectly the weight of the rotors will bear down on the base of the measuring chamber, leading to inaccuracy and meter damage and failure.Liquid can flow into the meter from either a horizontal or vertical direction. For vertical flow installations the most common orientation is for the liquid to rise through the meter (i.e. travel from bottom to top) to assist in air or entrained gas elimination. The meter operation is independent of the liquid flow direction thus there is no markings for inlet or outlet.Given the size and weight of these meters, it is recommended that any 3” or 4” meters have adequate support so that there is no excessive pressure on the process connections. Failure to support these meters during the installation process can result in structural damage to the flowmeter’s threaded connections/flanges during normal operation.2.2 Electrical InstallationAs a default the meter and totalizer is wired at the factory with the reed output pre-wired and DIP switches set for an integral rate/totaliser allowing self-powered operation of the instrument displays.The output(s) and function(s) available from a meter fitted with an integral instrument depends on the model of the instrument fitted and may include meter pulse repeater, pre-scaled pulse output, 4-20mA flow output or flowrate alarms.Refer to the option in the meter model number and relevant instrument manual. Unless programming details were provided at time of order the instrument program will contain factory default parameters. Integral instruments will however be programmed with the relevant calibration factor (K factor or scale factor) for the meter.Factory default settings can be found in the instrument instruction manual and it should be noted all output(s) are6 Installation2.2.1 Instrument Cable Twisted pair low capacitance shielded instrument cable 7 x 0.3mm (0.5mm²) should be used for electrical connection between the flowmeter and remote instrumentation, use Belden® number 9363 or similar. The cable drain or screen should be terminated on a DC COMMON or a specifically assigned shield termination at the readout instrument end only in order to protect the transmitted signal from mutual inductive interference. IMPORTANT, tape off & isolate the shield at the flowmeter end of the cable.The cable should not be run in a common conduit or parallel with power and high inductive load carrying cables as power surges may induce erroneous noise transients onto the transmitted pulse signal or cause damage to the electronics. Run the cable in separate conduit or with other low energy instrument cables. The maximum transmission distance is typically 1000m (3300 Ft).2.2.2 Hazardous area wiring Intrinsically safe wiring including using the reed switch pulse output as simple apparatus, wiring to an Intrinsically Safe Instrument must be undertaken in accordance with the rules, regulations and requirements applying to the territory in which the meter is being installed. The meters should only be connected by qualified staff, the qualified staff must have knowledge of protection classes, regulations & provisions for the apparatus in hazardous areas.If the flowmeter is fitted with an intrinsically safe instrument refer to the appropriate manual & I.S. supplement for wiring of the instrument inputs and outputs.2.3 Pulse Output selection for pulse meters Two types of output are available on each meter, open collector from Hall Effect sensors or reed switch contact. Each output type is linearly proportional to volumetric flow and each pulse is representative of an equal volume of liquid.2.3.1 Hall Effect Sensor Pulse Output The Hall Effect Sensor is a high resolution solid state 3 wire device providing an un-sourced, open collector, NPN transistor output. The term “un-sourced” means that no voltage is applied to the output from within the flowmeter, it must be pulled to a ‘high’ or ‘on’ state by between 5~24Vdc supplied from an external source, typically the receiving instrument.2.3.2 Reed Switch Pulse Output The reed switch output is a two wire normally open SPST voltage free contact ideal for installations without power or for use in hazardous area locations when Intrinsically Safe (I.S.) philosophy is adopted. Note: when using the reed switch output the liquid temperature must not change at a rate greater than 10ºC per minute (50ºF per minute).In general the reed switch life will exceed 2 billion actuations when switching less than 5Vdc @10mA as is the case when combined with the RT12 and RT40 instruments. 2.4 Meter Calibration Factor (K or scale Factor) Each flowmeter is individually calibrated and has the number of pulses per unit volume (eg pulses per litre or pulses per US gallon) entered into the program of the instrument. Please refer to relevant instrument manual for programming details. Nominal figures are shown in the specification section of this manual. For more accurate metering we recommend using the calibrated K factor. Calibration certification is available upon request from your distributor.Commissioning 73.0 Commissioning Once the meter has been mechanically installed the meter is ready for commissioning.The meter must NOT be run until the pipework is flushed of foreign matter, more often than not foreign matter is present after pipework fabrication or modification; weld slag, grinding dust, sealing tape & compound &/or surface rust are most common offenders.Flushing can be undertaken by utilizing a by-pass or removing the meter from the pipework. If neither is practical then the meter rotors must be removed prior to flushing (refer to Maintenance section of this manual for disassembly).After flushing or following long periods of shutdown the meter must be purged of air/vapour. This can be achieved by allowing the liquid to flow through the meter at a slow rate until all air/vapor is displaced. Never run the meter above its maximum flow or exceed 100kpa (1 bar, 15psi) pressure drop across the meter. Now the meter is ready for its operation to be confirmed by ensuring correct indication on the mechanical display. Refer if necessary to fault finding section of this manual. flowmeter isolation valve isolation valve Open downstream valve last4.0 Maintenance Adhering to the installation instructions in this manual should ensure your meter provides the required operational performance. These are mechanical meters and a periodic maintenance and inspection regime will maximize the operational availability of the meter.The frequency of maintenance depends on the application factors including liquid lubricity and abrasiveness and operational factors such as flowrate and temperature.BEFORE undertaking meter maintenance ensure the following :Associated alarm(s) or control output(s) are isolated so not to affect the process.The meter is isolated from any source of supply of liquid upstream or downstream.The meter is depressurized and liquid drained from the meter.4.1Disassembly of Pulse meter (Refer Exploded View)The meter is fitted with an integral instrument the instrument display assembly must be removed if required to gain access to the instrument terminal connections, instrument battery or pulse output board. This is achieved by:1.Undo the bezel screws and separate the display assembly from its base. Do not stress or damage thewires that connect the display assembly to the meter output. Take care not to misplace or damage O-ring(s).The pulse output board can now be accessed.2.To remove the pulse output board, first undo the screws that fix the instrument base to the flowmeter(Refer Exploded View).If required to gain access to the oval geared rotors undo the 8 body screws (5), carefully pry the meter body apart avoiding misplacing or damaging the O-ring (3) and rotors (2).Maintenance 94.2 Inspection (refer Exploded View)Inspect O-rings (3) for damage, chemical attack, deformity or any form. Remove, inspect & clean the rotors (2). Check the measuring chamber (1) for damage or scoring & redress if necessary, the rotor shafts should NOT be loose or able to be rotated.4.3 Re-assembly of meter (refer Exploded View)When re-installing the rotors (2) all four magnets MUST be visible when both rotors are in place. Both rotors will only engage correctly if fitted precisely at an orientation of 90 degrees to each other. Rotate the rotors slowly by hand to ensure they are correctly fitted at the same time check the rotor shafts & rotor bearings for wear.Fit the O-ring (3) into the groove and assemble the two parts of the meter, the body (1) & cap (4) align with a location pin.Fit the body cap screws (5) and tighten in a star sequence then carryout a final tighten in the same sequence to a firm torque. This sequence and procedure ensures the meter bodies are assembled correctly and evenly. Fit the pulse output board and instrument as appropriate.This sequence and procedure ensures the meter bodies are assembled correctly and evenly. Once completed,10 Maintenance 4.4 Spare PartsFault finding 11 5.0 Fault Finding Pulse meters have two distinct sections: the mechanical wetted section housing the rotors and the electrical section housing the pulse output board.Meters fitted with integral instruments have these two sections plus the instrument.The aim of fault finding is to trace the source of the fault to one of these sections.If a fault is traced to an instrument section, refer to the relevant instruction manual.Below are basic fault finding steps. Also refer to Trouble Shooting Guide on following page.Step 1 - Check application, installation and setup.Refer to Mechanical Installation section for installation and application factors that may affect the meter operation including pulsation and air entrainment or incorrect meter selection including incorrect flow rate, temperature and pressure or materials compatibility. Refer to Electrical Installation for correct wiring.Step 2 - Check for blockages.The most common cause of fault/unsatisfactory meter operation, particularly for new or altered installations, is due to blockage within the system or meter caused by foreign particles such as weld slag, sealing tape or compound, rust, etc.Step 3 - Ensure flow is present.No flow or lower than normal minimum flow may be attributed to a blocked strainer, jammed or damaged rotors within the flowmeter, malfunctioning pump, closed valves or low liquid level in feeder tank.Step 4 - Ensure oval gears within meter are rotating.Rotation of the oval gears can be heard by holding a screw driver blade to the meter body and pressing the handle hard against the ear lobe. If necessary test the meter with the flow turned off and turned on to familiarize yourself with the audible rotation signature.Step 5 - Ensure pulses are being generated during flowing conditions.A multimeter is often not fast enough to distinguish the pulse train from the reed switch or Hall Effect sensor. An oscilloscope will allow you to view the output pulse train. When viewing the Hall effect sensor pulse ensure a pull up resistor is installed between the pulse output and the supply voltage (refer electrical installation).Step 6 - Confirm Instrument Operation.If an associated instrument is connected to the flowmeter confirm its operation by simulating a pulse input onto the flow input terminals. In most instances a contact closure on the flow input terminals is an adequate simulation.12 Trouble shooting5.1 TROUBLE SHOOTINGNotes:IM-D-750~D-2500-Pulse 3216© 2017 Great Plains Industries, Inc., All Rights Reserved.Great Plains Industries, Inc. / 888-996-3837 / 。
