Radar level sensor or open channel level measurementRobust IP68 housingConnectible with connector Low power consumption 4-20 mA Power supply via AQ Logger (more than 2 years) The AQ Radar Sensor is designed for long-term measurement in manholes or outdoor locations without power supply. The sensor has the advantage of low power consumption. A device connected to the AQ IoT Data Logger can operate in combination with a flow meter for more than 2 years with a 60-minute storage interval and data sent 2 times a day. For faster intervention in case of problems, minimum or maximum alarm values are set on the device, which inform the user of a malfunctioning system at the moment of excess. The batteries of the devices can be changed. In an open channel the algorithm can be used to obtain channel flow data via the AQ WEB interface and the level. In case the device is connected to the mains, the level can be monitored online.
