Our Thermal Mass Flow Meters operate using a constant temperature system that employs two RTD sensors; one for sensing temperature, and one for sensing flow. The sensor is heated to a precise temperature above that of the gas passing by. The Gas conducts heat off the sensor in direct proportion to the mass flow rate. The temperature is used to set the heat on the flow sensor and correct for changes in the gas temperature.
Features
Measures process gas flow rate/total
Insertion probes: for 1.5" to 70" pipes
One standard 4-20mA output proportional to mass flow rate; HART communication option
One output is selectable for pulse/alarm, RS485 Modbus RTU
Application in natural gas with the high pressure
