Thermal Flow Switch

Product Specifications /Features

This Thermal Flow Meter 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 could anti water scale.
1. Measure Range: 1cm/s ~ 150cm/s(Water); 3cm/s ~ 300cm/s
(Oil); 0~50m/s(Gas)
2. Power Supply: DC24V,
3. Output: Relay; 3 wire NPN; 3 wire PNP; Replay; ( 4~20mA
need higher price)
4. Working Temperature: -25C ~ 80C
5. Max Pressure: 100bar 10Mpa
6. Connection: G1/2?
7. Protect Grade: IP67
The flow 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.
