HR7311 Radar Water Level Gauge-HighReach

HR7311 Radar Water Level Gauge

HR7311 is a small-scale, low-power radar water (liquid) level meter that can be used for non-contact liquid level measurement of surface (or pipeline) water; HR7311 adopts pulse coherent radar (PCR) technology, using 60G millimeter radar waves as carrier signals, and achieves millimeter level measurement accuracy through complex signal recognition algorithms.

The optimized wave cancellation filter design makes the measurement results more accurate and stable. Compared to traditional pulse radar level gauges, they have higher measurement accuracy, lower power consumption, and ultra-small volume; It is a cost-effective radar level gauge and during measurement cannot be affected by temperature gradients, air pressure, water vapor, water pollutants, and sediment .

A 60GHz range detector based on the working principle of microwave radar.

Continuous pulse detection, stable operation of 24/7, measurement error less than ± 5mm.

High-end signal processing technology can adapt well to water surface fluctuations and further avoid errors

Non-contact detection, good directivity, low transmission loss, and wide application range.

Patch antenna (40 °× 80 °), with a lens the size can be (11 °× 11 °).

Approximately 10 measurements per second, effectively eliminating the effects of surface waves and instrument vibrations

Application Fields

The product is mainly used for on-site water level data collection. The collected data can be transmitted to the upper computer or server through a communication interface and wireless device. Therefore, this product is often used as a measuring terminal for remote monitoring systems.

The product has low-consumption and is very energy-efficient. It can be powered by solar energy when continuously detecting in the field.

Application:

1) For water level monitoring of rivers, lakes and other natural waters, a monitoring network will be established through monitoring points to achieve linkage early warning in flood season.

2) Water level monitoring in reservoirs, sewage channels, and other storage areas for internal operation regulation.
