VIDI Flow is a battery-operated device that measures water flow and transmits data wirelessly.

VIDI Flow is a smart flow reading device for water distribution networks. It measures water flow and transmits the data wirelessly.

VIDI Flow is installed in combination with a flow meter with a pulse output. VIDI Flow counts the pulses generated by the flow meter when a certain water volume has passed the flow meter. After installation and activation, the device transmits information about the water flow in the network to the VIDI Cloud platform or to a third-party software (e.g., SCADA GIS).

With data from flow transmitters, water utilities can detect leakages faster and reduce non-revenue water.
