Relays
The DF-...WM evaluating electronics is used in applications where spo- radic flow rate measurement is required, or where simultaneous continuous monitoring is needed. It converts the digital frequency signal from the sensor to a limit contact.
The limit value over the entire mea- suring range can be set with a po- tentiometer with calibrated scale. The ready state is indicated by a green LED. When the flow rate drops below the setpoint, a red LED flashes. The relay can be shorted and disabled by pressing a button. The flow rate can be determined and the potentiometer scale can be read by rotating the potentiometer from the largest to the smallest value (until the red diode flashes).
The front panel on the electronics and vane are displaced by
180°. This means that the operator can see from two directi- ons whether flow is available. The power supply of the device and the relay output are connected with a 7-pin connector or a 1.5 m cable. (A cable can only be used for flange con-nection.)
