APPLICATIONBattery-powered ultrasonic water meters of the FDT100 SERIES type series are intended for technological measurements of instantaneous flow rate and consumption in water-supply networks, and archiving of the measured data. Measurement of water pressure in piping is also possible. The technical capabilities including high measurement accuracy and long-term stability over a wide range of measured values make it possible to use the meters, apart from the conventional measurements, for monitoring leakage and the general condition of water supply networks. The FDT100 SERIES water meters do not require external power, do not include any moving parts or filters to prevent choking with mechanical impurities and, compared to conventional water meters, have significantly lower hydraulic losses.. Flow meters shall be used in standard non-explosive environments.Any installation of flow meter must be in conformity with technical conditions mentioned in this manual. 2. MEASUREMENT METHODThe measurement method used is a single-beam pulse transit-time method based on determination of the time needed for an ultrasonic pulse wave to cross the distance between two probes embedded in piping. Each of the probes functions as the sender and receiver in turns so that the ultrasonic wave travels in turns in and against the water flow direction. This arrangement allows for effective elimination of errors due to asymmetry in the probe locations.3. TECHNICAL DESCRIPTION3.1. Meter characteristicsThe FDT100 SERIES ultrasonic water meter is an electronic device used to measure the water flow rate in a fully flooded piping. It is manufactured and supplied in two versions: compact and remote. The compact version, designated FDT100 .SERIES , has the electronic unit attached directly onto the flow sensor housing. The remote version, designated FDT100-R .SERIES, has the electronic unit separated from the sensor and connected with it by means of a cable ( length 6m). The electronic unit is accommodated in a separate box that can be fitted on a wall.In the standard configuration, the meter software allows for measuring and display of the instantaneous flow rate and total volume of water passed through the meter since the volume counter was last reset. The meter is provided with a passive pulse output including an optocoupler. The pulse length is 40ms. The meter include passive current output. The meter is supplied suitable for use in drinking-water supply systems.DN 1¼" (32) 1½" (40)2" (50) 2½" (65)3" (80) 4" (100)5" (125) 6" (150)8" (200) L [inch] / [mm] 10.2/260 11.8/30011.8/30011.8/30013.8/35013.8/350 13.8/350 13.8/35013.8/350D [inch] / [mm] 5.5/140 5.9/150 6.5/1657.3/1857.9/2008.7/2209.8/250 11.2/28513.4/340Weight [lb] / [kg] 11/5 16.5/7.523/10.525/11.534/15.540/18 51/23 58/26.582/373.2.3. Ultrasonic sensor unitThe surface finish is by paint of orange hue (RAL 1017).Two M8 grummets are intended for cables of outside diameter 3.5 to 5mm to be connected to the selected output signal terminals. On delivery, these grummets are blinded. The third grummet (M12) is provided only in the case of the remote meter version and is intended for the cable of diameter 6.5 to 8mm connecting the sensor and the remote electronic unit. The connecting cable is supplied attached to the electronic unit with the other end ready to be connected to the sensor terminal board.The meter display is located under the transparent plastic cover. The push-button on the unit box is used to select the desired display mode: either instantaneous flow rate (in gallons per minute GPM or m3/hour), the total fluid volume (in thousands of gallons or m3) passed through the meter sensor since the volume counter was last reset, or the fluid pressure (in bar). The actual quantity displayed is indicated at the bottom line by the symbol j. In the case of a meter failure, the respective error message (E1 through to E5) will be indicated by the same symbol j - see the picture below. A recess in the unit box is for an optical probe to be applied onto the recessed surface to read the stored data. Also found under the box lid is the meter rating plate:unit – terminal boardsensor3.2.5. SeparateIn the case of the remote version of the FDT100 SERIES water meter, attached to the sensor housing is a terminal board in an aluminium box with a sealed lid. The terminal box is provided with a M12 grommet for a cable of diameter 6.5 to 8mm, a valve preventing moisture condensation inside the box and four spring-loaded WAGO terminals to which the ultrasonic probes signals are brought. Connected to these terminals are the wires of the cable leading to the remote electronic unit.4.

Meter installationrecommendations5.2.1. GeneralIn the basic arrangement (flow direction from left to right and the sensor installed into a horizontal piping section),The interconnection between the meter sensor and electronic unit (the remote meter version) is made by a shielded cable with the shielding connected to the earth potential at the sensor terminal board. It is recommended that all output signals (the pulse and current outputs) be connected using shielded cables with the shielding connected to the earth potential on the side of the plant control system. The meter sensor shall also be carefully grounded. To do that, connect the grounding bolt on the sensor flange with the piping flanges using an grounding conductor of cross-section of at least 4mm2 .fitting5.2.2. MechanicalThe ultrasonic sensor shall be fitted into the water piping across piping flanges matching the meter flanges ANSI.connections5.2.3. ElectricalThe compact meter version (FDT100 SERIES): the electrical interconnection operation consists of connecting the output signal cables to the respective terminals on terminal board in the electronic unit. The terminal board can be accessed upon removal of the plastic lid at the top of the unit box. The lid is secured in position by means of two M4 screws with hexagonal socket heads for Alien wrench size 2mm.At the bottom side of the plastic lid there are two slots 8mm wide where a flat tool can be inserted to help lift the lid from the box. It is recommended to insert a screwdriver into one of the slots and slightly pry upwards. The locations of the slots are shown in the picture below. Prior to replacing the lid, apply a thin layer of glycerine or silicon oil on the sealing O-ring.When replacing the lid, the 3mm hole at the bottom side of the plastic lid should be fitted onto the guide pin ofdiameter 2.5mm press-fitted at the box bottom.the terminal box is held in position by means of four M4 screws with hexagonal socket heads for Alien wrench size 3mm.The output signal cable connections the terminal board are made in the same way as shown above for the case of the compact meter version.The compact meter version, type FDT100 SERIESThe remote meter version, type FDT100 SERIESpoint in the piping, bled and filled with the technological fluid, it is ready for operation. The condition of readiness to start is indicated by disappearance of the error messages j at the bottom of the meter display unit. Using the control push-button, check the selection of measurement modes: the instantaneous flow rate, total volume passed and pressure (if applicable).An pulse output is found on all FDT100 SERIES water meters irrespective of their version or configuration. In includes an optocoupler connected to terminals 7 and 8 (terminal board X1); the permitted current loading is 10mA, the pulse length 40ms. On a customer’s request the pulse length can be set at 2ms. If voltage pulses are required, use an7.2.2. CurrentoutputThe current output 4 - 20mA is connected to terminals 5 and 6 at the output terminal board. Upon attaining the output current level of 20mA (corresponding to Qmax), the current will not exceed this value and the error message E4 will appear on the display (see Section 7.5. below). To utilize the output current function, use an external power source of 10 to 24V DC and the interconnection at the output terminal board as described in Section 5.2.3. The maximum permitted resistance (the ohm resistance of the cable + input resistance of the co-operating equipment) of the current output circuit shall be determined using the following formula:U source [V] - 7R s[Ω] =0.02.7.3. Error identification functionMeter errors shall be identified as E1 through to E5 by symbol j shown at the bottom of the display unit.Error identification symbols: E1 - the ultrasonic signal cannot freely propagate in the sensor cavity (due to thepresence of air or mechanical particles)E2 - too great a difference between the signal travel times in and against the fluidflow direction (possibly due to the presence of air at one of the probes, whichmay be a temporary condition during the operation of filling the piping withfluid, or due to contamination of the face part of one of the probes)E3 - A/D converter error (e.g. due to strong interference)E4 - flow rate in excess of q sE5 - flat meter batteryShould the display go completely blank, check the battery condition (the voltage should be over 3V). Replace defective battery using the procedure described in Section 7.6. Should the battery replacement fail to restore the correct meter function, send the meter for repair to the manufacturer’s service centre.7.4. Battery life and replacementElectronic unit is equipped with battery SAFT LITHIUM 3,6V /3,6Ah LSH 14 "light" (size C) containing less than 1g of lithium and is equipped with plastic case capable of using of either C and D size battery. Lifetime of LSH 14 "lite" battery is 1 year since date of production and can be replaced by battery LITHIUM 3.6V / 16Ah LS 33600 (size D) with lifetime up to 8 years, with using of communication functions up to 6 years. Plastic case is not used for D size battery LSH 14 "light" battery is used as a "transport battery," because it is non-restricted to transport/non-assigned to Class 9 according Lithium battery transport regulation (Ref. TC-LSH 14"light"-09/03-1).To replace the meter battery, first remove the plastic lid on the electronic unit box held in position by two M4 screws with hexagonal socket heads (use Alien wrench, size 2mm), see Section 5.2.3., then loosen three M3 screws holding the electronic module in the aluminium box and pull the module outside the box. While doing that, make sure you do not damage any metrological or company seals. The electronic module can only be removed as far as probe conductors and output signal cables permit. The battery is located in a holder at the bottom of the unit; pull the battery free and replace it with a new one. Mind the correct polarity as indicated on a plate on the battery holder. Push the electronic module back into the box, tighten the holding bolts, replace the box lid, fix its position with screw and apply assembly seal on one of them.8. CALIBRATIONThe standard calibration is done with respect to the pulse output. In that case the measurement error at the current output will be approx. 1% higher than that at the pulse output. If the customer requires calibration for the current output, it can be done and the additional error of about 1% will then appear at the pulse output.W ARRANT Y/DISCLAIMEROMEGA ENGINEERING,INC.warrants this unit to be free of defects in materials and workmanship for a period of13months from date of purchase.OMEGA’s W ARRANTY adds an additional one(1)month grace period to the normal one(1)year product warranty to cover handling and shipping time.This ensures that OMEGA’s customers receive maximum coverage on each product.If the unit malfunctions,it must be returned to the factory for evaluation.OMEGA’s Customer Service Department will issue an Authorized Return(AR)number immediately upon phone or written request.
