The electric pneumatic remote tank level monitoring system features a device that outputs a stream of constant airflow to the sounding pipe installed in the cabin via a measurement unit. When the air pressure in the sounding pipe is balanced with the liquid pressure in the bottom of the cabin, the redundant air overflows from the sound pipe. The pressure measuring element in the measurement unit continuously and immediately turns air pressure into a current signal. It then sends an output to the field instruments or communication cabinet.
The pressure measuring element of electric pneumatic type remote tank monitoring system doesn't come in direct contact with the measured medium, which extends the service life of the pressure measuring element and is more suitable for occasions with limited installation and maintenance space.
