RS485 Wireless Radar Water Level Sensor Transmitter 12V-24V MODBUS Protocol

The KNF-1321 is a radar flowmeter module that integrates liquid level measurement and flow rate measurement based on microwave technology. It can be used for non-contact flow measurement in open channels, rivers, irrigation canals, underground drainage networks, flood warning and other occasions. This product features low power consumption, compact size, high reliability and easy maintenance. The measurement process is not affected by factors such as temperature, sediment, river pollutants, and floating objects on the water surface. Among them, the ranging radar and flow rate radar are respectively default configured to be compatible with ASCII and MODBUS protocols at the factory, and can switch protocol modes according to corresponding instructions by themselves.

Product features

(1). Non-contact measurement, combined with cross-sectional parameters to calculate flow rate, is not affected by wind, temperature, haze, sediment, floating objects on the water surface, etc.
(2). It is applicable to various measurement conditions and can output measurement data of flow velocity, water level and flow rate.
(3). Low power consumption, compact size, high reliability, and easy maintenance;
