The unique FMA-900 air velocity transducer utilizes both a velocity sensor and a temperature sensor to accurately measure air velocity (in SFPM, standard feet per minute). The built-in temperature sensor automatically corrects the flowrate for temperature variations. Both sensors are rugged glass-coated Platinum resistance detectors (RTDs). The circuit heats the velocity sensor to a constant temperature differential above ambient temperature and measures the cooling effect of the air flow. This design provides excellent low velocity sensitivity and high accuracy. The FMA-900 also features negligible pressure drop. To obtain mass flow rate in SCFM (standard cubic feet/minute), the SFPM velocity indicated by the FMA-900 is multiplied by the cross-sectional area of the pipe or duct in square feet. A traverse across the pipe or duct can be performed to determine the mounting location for average velocity indication. The FMA-900 can be mounted in pipes (down to 38 mm [1.5"] size) with the use of OMEGA® SSLK compression fittings (SSLK-14-14, $8.50). PTFE ferrules are required (T-FER-1/4, $40/10 pack). Each unit is individually calibrated in OMEGA’s NIST-traceable wind tunnel. Suggested power supply; FPW-15, $75. RTD TEMP SENSOR FLOW RUGGED THERMAL MASS VELOCITY SENSOR For compatible meters and controllers, see the iSeries, Section M. Replacement mating connector, model FMA-3CON, $25. F-113 FMA-902-V-R, $852,shown smaller than actual size. Models with remote probe add suffix “-R” and $30.
