FMA1802A

FMA1802A is a 1800A series, electronic gas mass flow meter that provides for monitoring the flow of a wide variety of gases. Utilizing heat transfer through a heated tube to measure molecular gas flow rate, the FMA1800A provides a measurement of direct gas mass flow rate, without the need to compensate for variations in gas temperature or pressure (within stated limits). The FMA1800A series has both an integral 3¹/2 digit display and analog output. The display is tiltable over 90 degrees for viewing convenience. Due to their low cost, digital display, analog output capability, and insensitivity to variations in gas temperature and pressure, the FMA1800A series is an ideal substitutes for many variable area flow meter applications. 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 a FMA18RC remote cable assembly users must then build their own assembly for panel mounting the LCD.
