Submersible Water Level Sensor
EM500-SWL
EM500-SWL is designed to measure the tank level or open water applications while fully submersed in liquid. It is robust and sealed to prevent corrosion and failure.
Smart Water Management >>>
In recent years, significant strides have been taken to implement IoT-based monitoring solutions in various areas such as liquid level measurement. Take water level in wells as an instance, monitoring and measuring the level with IoT-based system will protect users from running into serious problems such as water outages.




Smart Gasoline Management >>>
Faced with increasing challenges, enterprises are continuously trying to deploy IoT technology into gasoline level monitoring and measurements to detect real-time accurate gasoline volume despite wide temperature swings, rough handling and harsh environments.
