CE Reads Gas Mass Flow Without Temperature or Pressure Compensation Available in Economical Aluminum or Corrosion- Resistant 316 SS Tiltable LCD Display for Easy Reading NIST Traceable Calibration Included View related products - Electronic Mass Flowmeters Click to scroll below to order See Specs PDF Manuals View a printer friendly page The FMA1700A/1800A Series eletronic gas mass flowmeters provide for monitoring the flow of a wide variety of gases from 10 SCCM up to 1000 SLM. Utilizing heat transfer through a heated tube to measure molecular gas flow rate, the FMA1700A/1800A provides measurement of direct gas mass flow rate, without the need to compensate for variations in gas temperature or pressure (within stated limits). They are available in an economical aluminum/brass construction for typical gas flows and a 316 SS construction for applications requiring more corrosion resistance. The FMA1700A series without integral display is supplied with a field selectable analog 0 to 5 Vdc or 4 to 20 mA output for remote monitoring; the FMA1800A series has both an integral 3? digit display and analog output. The display is tiltable over 90 degrees for viewing convenience. The display is calibrated standard to read out directly in SCCM or SLM for nitrogen (other gas calibrations available on special order). Due to their low cost, digital display, analog output capability, and insensitivity to variations in gas temperature and pressure, the FMA1700A/1800A Series are ideal substitutes for many rotameter applications. When used with the FMA178BP portable battery pack, the FMA1800A Series are ideal for in-the-field calibration of flowmeters or testing of air sampling equipment. The FMA178BP battery pack includes batteries, recharger, and carrying case with shoulder strap and belt loop. With the FMA178BP, the flowmeter can operate in excess of 40 hours; the batteries can be recharged at least 200 times. The FMA1700A/1800A Series require 12 to 26 Vdc power @ 200 mA maximum, which can be supplied by the FMA178PW plug-in socket power supply. The electronics are reverse polarity protected and has externallyaccessible fusing. Model number FMA178C (supplied separately) provides a mating 9-pin “D” connector with 3 feet of ribbon cable for accessing the 0 to 5 Vdc output signal and power input connections (use FMA178C-MA for 4 to 20 mA output signal connection). The LCD supplied with the FMA1800A Series is connected to the lower electronics via a modular plug. The LCD can be remotely located by purchasing an FMA18RC remote cable assemblyyou must then build your own assembly for panel mounting the LCD.

Note: * Comes with dual 3/4 FNPT connections instead of compression fittings. Comes complete with compression fittings, operator's manual, and NIST traceable certficate. Power supplies sold separately. Flow ranges specified are for nitrogen or air at 20 psig. When used for other gases, a multiplication factor is used to determine the flow rate, and the digital display must be rescaled in the field. To request a custom calibration add the gas abbreviation and pressure as a suffix to the model number. Custom calibrations done at ambient temperature only.
