Highly sensitive so2 Liquefaction System Wireless Sensors

Continuous level sensors are used for measuring levels to a specific limit, but they provide accurate results. Point level sensors, on the other hand, only determine if the liquid level is high or low. The level sensors are usually connected to an output unit for transmitting the results to a monitoring system.
