A flap-type flow-meter is ideal wherever a rugged, reliable and economical device is required for visualization and monitoring of flows.

The KLA series flow-meter is based on the same operating principle as the KFS series. Inside the meter a flap moves up and down in analogy to the amount of liquid flowing through.

In the KLA-GS version the quantity is directly indicated by the flap; The flow meter is equipped with hard glass screens at the front and at the back. The flow-rate reading is done on an integrated scale into the front hard glass screen.

The economical version KLA Standard provides a direct visual display.
In both versions a magnet transmits the movement of the flap to a pointer in the
case.

For process control, the measuring device can be equipped with:
- 1 or 2 inductive contacts
- 1 analogue transmitter, 4-20 mA output: angular position transducer (The signal must be linearized).
