Submersible pressure sensor not affected by foam, wind, or rain
IP67 full sealed plastic waterproof design (Transceiver is not included)
Measuring medium: water (customizable for oil and other non-corrosive media)
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.
