Calibrating the flow meter with the tank method

Mode of operation

With the tank method, a large quantity of water will be applied from the tank over a specific time.

The flow meter measures the impulses during this time.

After the application, you must enter the quantity of water that has been applied.

The computer calculates the number of impulses per litre.

		WARNING
