FMA1845A

FMA1845A is a FMA1800A series economical gas mass flow meter for clean gases with optional integral display. It is an electronic gas mass flow meter for monitoring the flow of a wide variety of gases from 10SCCM upto 1000SLM. Utilizing heat transfer through a heated tube to measure molecular gas flow rate, this device provides measurement of direct gas mass flow rate, without the need to compensate for variations in gas temperature or pressure (within stated limits). It has both an integral 3¹⁄₂ 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. Due to their low cost, digital display, analog output capability, and insensitivity to variations in gas temperature and pressure, the FMA1800A is ideal substitutes for many rotameter applications. It is ideal for in-the-field calibration of flow meters or testing of air sampling equipment.
