R718VB-Wireless Capacitive Proximity Sensor

   

R718VB is to detect the level of toilet tank water, liquid hand soap, and liquid level of non-metallic pipes (pipe outside diameter: D ≥11MM). This device is connected to a non-contact capacitive sensor, which can be installed on the exterior of the container. Without direct contact, the sensor can detect the current level of water or liquid hand soap within the measurement range. The collected data could be transmitted to and displayed by other devices through the wireless network.
