GE-324 Thermal Flow Switch (Visual LED
This Thermal Flow Switch is used to measure and monitor the
liquid flow state, with LED to display the flow condition
and sent alarm signal. The flow set point is adjustable by
the user directly, No pressure loss, and stabitly with
sensitive performance. It have a stainless shell, could work
the the anti explosion proof environment.

switches feature thermal dispersion technology in which the
temperature difference is greatest in a no-flow condition
and decreases as flow increases, cooling the heated RTD.
Changes in flow velocity directly affect the extent to which
heat dissipates and, in turn, the magnitude of the
temperature difference between the RTDs.
An electronic control circuit converts the RTD temperature
difference into a DC voltage signal. Both of these signals
are provided at output terminals and are used to drive two
adjustable-setpoint alarm circuits. Both alarms are
independently field configurable for flow, liquid
level/interface or temperature operation.
