VIDI Positioner is a battery-operated device that detects the position of a gate valve and transmits data wirelessly.

VIDI Positioner is a smart device for indicating the position of gate valves. This IoT sensor detects the open/close position of a gate valve and transmits the data wirelessly.

The device is installed in combination with an AVK extension spindle on multi turn valves. After installation and activation, the device transmits information about the position of the valve to the VIDI Cloud platform or to a third-party software (e.g., SCADA or GIS).

VIDI Positioner provides water utilities with valuable insights into the use of valves by remotely monitoring the position of a valve by indicating whether it is open, close, or any percentages in between. Based on the provided information, water utilities can optimise the operation of the water distribution network, extend the lifetime of assets, and efficiently reduce water loss.

Variant 3004/002-001

Features

Positioner:

Communication: NB-IoT (band 8 & 20) or LoRa® (868MHz)
Detects the position of the valve and transmits data to the VIDI Cloud or a third-party software
Material: Robust plastic cover, IP68*
Easy provisioning and configuration via NFC (Via AVK Assist app)
Operating temperature: -20 up to +65 °C
Fits on: AVK extension spindles (#14-22 and #23-32)
