Application :
FM12 series velocity transmitter is used for measuring low pressure of air and combustible gases in order to monitor and control building automation, HVAC and cleanroom systems. These transmitters boast of their outstanding performance, high quality and economical pricing. This transmitter can detect differential pressure or gauge pressurethen convert this pressure difference to a proportional analogue output signal, in order to monitor and control building automation with precise pressure and flow.
