HC-LM04 Level Sensor

HC-LM04 level sensor is an 80GHz radar designed and developed specifically for hydrological detection. Adopting a non-contact installation design, it is compact in size and structure. High precision, low power consumption, and strong anti-interference ability. Suitable for water level monitoring of lakes, rivers, flash floods, reservoirs, sewage pipelines, etc.

Application:

This product can be applied to liquid level monitoring in open channels, rivers, reservoirs, flood prevention warnings, and other areas.

Features:

  • The farthest measurement distance is 40m
  • Distance measurement with millimeter level accuracy
  • Non contact measurement effectively reduces interference from harsh environments and achieves maintenance free operation
  • High precision, low power consumption, strong anti-interference ability
