Omega electronic laboratory gas mass flowmeter tester
The FMA1700/1800 Series electronic gas mass flow meters provide for monitoring the flow of a wide variety of gases from 0-10 SCCM up to 50 SLM. Utilizing heat transfer through a heated tube to measure molecular gas flowrate, the FMA1700/1800 provides measurement of direct gas mass flow rate, without the need to compensate for variations in gas temperature or pressure (within stated limits). The standard model FMA 1728, aluminum/brass body, 0-50 SLPM, costs $575. This is the model FMA 1728 ST (stainless body) but with the non-corrosive 316 Stainless body option. It costs $770 new.

From the website: Available in an economical aluminum/brass construction for typical gas flows and a 316 SS construction for applications requiring more corrosion resistance. The FMA1700 series without integral display is supplied with a field selectable analog 0-5 Vdc or 4-20 mA output for remote monitoring; the FMA1800 series has both an integral 3 1 /2 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 FMA1700/1800 series are ideal substitutes for many rotameter applications. When used with the FMA178BP portable battery pack, the FMA1800 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 FMA1700/1800 series require 12 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 externally-accessible fusing. Model number FMA178C (supplied separately) provides a mating 9-pin “D†connector with 3 feet of ribbon cable for accessing the 0-5 Vdc output signal and power input connections (use FMA178C-MA for 4-20 mA output signal connection).
