Kobold DF-K Digital Display Vane Flowmeter

1 minute, 23 seconds Read

The DF-K evaluating electronics outputs the sensor frequency signal to a display, and converts it to an analogue signal and two limit contacts. The top display line of the double-spaced display shows the flow value with measuring unit and the bottom line a bargraph indicator proportional to the measuring value.

The two relays with floating output change over contacts continuously monitor the flow values. Switching point,  hysteresis,  a window point, and switch on or off delay can be set separately for each relay. The switching points can also be set directly by using the control keys without having to change over into the menu. A red LED indicates with the switching status.

The analogue output is optionally available as current output with  0(4)… 20 mA or as voltage output with 0 …10 V. A Min./Max. reading memory determines  the  extreme  readings  of the flow. If the maximum set flow (exceeded range) is exceeded, it will be shown on the display. The set .parameters can be protected against unauthorised alteration by using a password function. The device is connected with a 10-wire cable.
