Description

Designed to measure the volume of cold or hot water flowing in pipelines of cold and hot water supply systems.

The principle of operation of the counter is to measure the number of revolutions of the impeller rotating under the action of the flow of flowing water. The counter has an electronic impeller speed sensor. The signal from the sensor goes to a microprocessor device, which calculates the volume of water that has passed through the meter. The volume value is displayed on the indicator device.
