Oil well fracturing operation tank car liquid level measurement device

The utility model relates to a liquid level measurement technical field specifically provides an oil well fracturing operation tank car liquid level measurement device, including the operation jar, level sensor, current transmitter, the microprocesso, display element and audible -visual annunciator, level sensor installs in the operation jar, the level sensor junction current changer, current transmitter connects microprocessor, microprocessor control display element and audible -visual annunciator work, microprocessor and display element all set up at the flame proof incasement, audible -visual annunciator sets up in the top of flame proof incasement, the flame proof case is installed behind the mudguard is controlled to the tank car, add one deck lightning protection flame proof layer on current transmitter's the circuit board. The utility model is simple in operation it uses to be fit for the workman, have lightning protection and flame proof structure, alarm signal is independently exported by two no. 2 relays, and two output relays are used for increasing the reliability of reporting to the police, and the ultrasonic wave level gauge of comparing traditionally has frost resisting characteristics, and the specially adapted is chilly adverse circumstances in the north.
