A laminar flow element (LFE) inside the meter forces the gas into laminar (streamlined) flow. Inside this region, the Poiseuille equation dictates that the volumetric flow rate be linearly related to thepressure drop. A differential pressure sensor is used to measure the pressure drop along a fixed distance of the LFE. This, along with the viscosity of the gas, is used to accurately determine the volumetric flow rate. Separate absolute temperature and pressure sensors are incorporated and correct the volumetric flow rate to a set of standard conditions. This standardized flow rate is commonly called the mass flow rate and is reported in units such as standard cubic feet per minute (SCFM) or standard liters per minute (SLM).Standard units include a 0 to 5V output (4 to 20 mA optional) and RS232 communications. The gas select feature can be adjusted from the front keypad or via RS232 communications. Volumetric flow, mass flow, absolute pressure, and temperature can all be viewed or recorded through the RS232 connection. It is also possible to multi-drop up to 26 units on the same serial connection to a distance of 38 m (125'). These flow meters are available in a portable version (“-B” option), the battery charge will last up to 18 hours.FMA-1600A SeriesSpecificationsAccuracy: ±(0.8% of rdg + 0.2% FS)Repeatability: ±0.2%Turndown Ratio: 200:1Response Time: 10 ms typical default response time for 63.2% of a step change.

For volumetric flow rate as standard output add suffix “-VOL” to the model number; no additional cost. Standard output is 0 to 5V, for optional 4 to 20 mA output, add suffix, “-I” to model number; for additional cost.For two 4 to 20 mA output, add suffix “-I2” to model number; for additional cost.For two 0 to 5V output, add suffix “V2” to model number; for additional cost.**Optional secondary output are scaled the same as the primary output scale. For an alternate output scale add suffix “-T” to the model number for temperature or “-P” for pressure; no additional cost.For a portable version of the meter add suffix “-B” to the model number; for additional cost. Portable versions have an integral battery on the meter and come with one 9V battery installed. Option not available on “-I” or “I2” models where 4 to 20 mA is the chosen output.For units scaled in SCFH, add suffix “-SCFH” to model number; no additional cost. Please specify the desired range in SCFH.For totalizer option, add suffix “-TOT” to the model number; for additional cost. Please specify resolution.This is a 6-digit counter. Examples: For totalizing in liters with 1/100 liter resolution, the max count would be 9999.99. For totalizing in liters with 1 liter resolution, the max count would be 999999.Ordering Examples: FMA-1601A, 0.5 SCCM mass flow meter.FVL-1619A-VOL, 500 SCCM volumetric flow meter.。

One RTD is the velocity sensor, while the other RTD provides ambient air temperature compensation. The velocity sensor is heated to maintain a constant (approximately 30°C) temperature differential above the ambient air temperature, as measured by the second RTD element. The cooling effect of the air flow experienced by the velocity sensor is measured and converted to an electrical output signal proportional to air velocity. The FMA-900 is provided with a 13" long probe as standard. The 304SS tubing is provided with inch marks for ease of insertion depth.UnpackingThe following items are supplied with the FMA-900:•FMA-900 Series Air Velocity Transducer •Mating connector•Removable plastic protective cover (supplied on the sensor tip)•Operator’s manual1-1Important Considerations Before Installationintrinsically safe. Do not use for flammable or hazardous gases, or inhazardous areas.The FMA-900 air velocity transducer is intended for use with clean air or !nitrogen ONLY. Do not use with other gases, as other gases will produce anuncalibrated, non-linear output signal. In addition, air carrying dust or oil (suchas found in blower/compressor systems that utilize oil) can lead to coating of thesensor and thus, inaccurate readings. Refer to the Maintenance section for moreinformation on cleaning the sensor.The FMA-900 is a bi-directional device; flow in the forward or reverse directionprovides the same output.Installing the FlowmeterThe FMA-900 air velocity transducer can be mounted vertically or horizontallywithout shift in calibration.1.Remove the plastic protective cap from the sensor tip.2.Run a length of straight pipe before and after the flowmeter. The amount ofupstream straight pipe run required depends upon the type of obstruction whichis immediately upstream of the flow sensor. See Table 2-1 for specificrequirements. Downstream of the flow sensor, in all situations, run 5 diametersof straight pipe, regardless of the downstream obstruction.3.Align the FMA-900 with the air flow. Make sure the width of the electronics box(2 inches) is parallel with the flow stream.The score line on the tubing is another way of aligning the air flow sensor withthe flow stream. The score line starts from the center of the transducer windowand as a result it can be aligned properly.One means of installing the probe into a flow stream is to utilize a compressionfitting, such as OMEGA’s SSLK-14-14 stainless steel compression fitting withTeflon ferrules, which permits adjustment of the insertion depth of the probe.On Remote Probe Models (-R), connect the remote probe cable to the ElectronicHousing.1-2Table 2-1 Piping Requirements1-3Wiring the Flowmeter1.Connect pins as follows:PLUG PIN NO.DESCRIPTION1 0-5 Vdc or 4-20 mA Output (−)2 0-5 Vdc or 4-20 mA Output (+)3Power Supply (+)4No Connection5No Connection6Power Supply (−)2.Blow clean air through the FMA-900.3.Install the sensor into the pipe or duct.Measuring Air FlowThe FMA-900 measures standard velocity, which is the mass velocity of the airreferenced to 25°C and 760 mm Hg. No temperature or pressure corrections arerequired. Where SCFM (standard cubic feet per minute) measurements aredesired:1.Locate the point of average velocity in the pipe or duct.2.In round pipes, under turbulent flow conditions (where the Reynolds number isgreater than 5,000), mount the velocity sensor approximately 1⁄8of a pipediameter in from the the pipe wall. For example, in an 8" diameter pipe, mountthe probe 1" in from the pipe wall.3.For pipes or ducts where the flow is not turbulent, or the flow profile is notsymmetrical (due to inadequate straight pipe runs, etc.), perform a traverse ofthe duct, in accordance with standard duct traversal methods as recommendedby ASHRAE or the National Air Balance Council.4.To obtain SCFM, once the probe is mounted in the location of average velocity,multiply the average velocity readings (in SFPM, standard feet per minute) bythe cross-sectional area of the pipe or duct, in square feet. For standard pipe,these values can be found in the technical section of the OMEGA CompleteFlow and Level Measurement Handbook and Encyclopedia®. MaintenanceExcept for intermittent removal of the sensor from the line for cleaning, there isno routine maintenance for the FMA-900. If the probe becomes coated with dust,blow the dust away with clean air. If the probe is coated with sticky material,clean it with a solvent which is compatible with epoxy, glass, and 304SS, andwhich will not leave a residue on the sensor. You may clean the sensor withwater or alcohol (Ethanol) and an artist’s brush.CalibrationEach FMA-900 is individually calibrated in a NIST-traceable wind tunnel. Forcalibration certification or calibrating to a new range, the unit must be returnedto OMEGA.
