Radar Narrow Beam 3 In 1 Water Level Water Surface Velocity Water Flow Sensor

Short Description:

There are two options for measuring liquid level: 7 meters and 40 meters. It is a non-contact and integrated flow monitoring device that can continuously measure flow rate, water level and flow. This product can be used for non-contact flow measurement in open channels, rivers, irrigation channels, underground drainage pipeline networks, flood control warnings, etc. We can provide servers and software, and support various wireless modules, GPRS, 4G, WIFI, LORA, LORAWAN.
