Interface Level Transmitter can provide high-speed, reliable and high-precision continuous measurement in explosive gas environment. The output is in analog or digital form. The analog output form is two-wire 4-20mA+Hart; the digital output adopts RS485 (Modbus protocol) communication. When interface level transmitter working, it can be one or more floating balls. The floating ball can be suspended on the liquid-gas interface and liquid-liquid interface in the storage tank respectively, and move synchronously with them, WPX902 interface level transmitter realizes the real-time detection of the liquid level or interface of the liquid tanks.
