Radar

Level transmitter

The Radar Water Level Sensor is independently developed by our company, utilizing FMCW (Frequency-Modulated Continuous Wave) technology with a 60GHz millimeter-wave radar signal as the carrier wave. The product features high measurement accuracy, low power consumption, compact size, and lightweight design. Its measurement process remains unaffected by environmental factors such as temperature, air pressure, sediment, dust, river pollutants, surface floating debris, or atmospheric conditions, while also demonstrating strong wind resistance and anti-vibration capabilities. The optimized algorithm ensures enhanced precision and stability in measurement results.

The level transmitter with ultra-low power consumption,IP68 protection rating, RS485 communication interface and standard Modbus protocol, It is equipped with a corrosion-resistant housing , suitable for operation in various harsh working environments.

A silicon piezoresistive level sensor with a stainless steel isolation diaphragm is used as the level signal measurement component, The level signal is acquired through a high-precision AD converter, enabling zero-point compensation and temperature performance compensation for liquid level measurement across a wide temperature range.
