Liquid level measuring device for oil well fracturing operation tank car

Abstract

The invention relates to the technical field of liquid level measurement and particularly provides a liquid level measuring device for an oil well fracturing operation tank car. The liquid level measuring device comprises an operation tank, a liquid level sensor, a current transducer, a micro processor, a display unit and an audible and visual alarm, wherein the liquid level sensor is mounted in the operation tank; the liquid level sensor is connected with the current transducer; the current transducer is connected with the micro processor; the micro processor controls the display unit and the audible and visual alarm to work; the micro processor and the display unit are arranged in an explosion suppression tank; the audible and visual alarm is arranged at the top end in the explosion suppression tank; the explosion suppression tank is mounted behind left and right fenders of a tank car; and a lightning-protection explosion suppression layer is additionally arranged on a circuit board of the current transducer. The liquid level measuring device is simple to operate and suitable for a worker to use, and high in reliability because of the lightning-protection and explosion suppression structure; an alarm signal is independently output by two relays which are used for increasing the alarm reliability; and compared with a conventional ultrasonic liquid level meter, the liquid level measuring device has cold-resistant characteristic and is especially suitable for a cold severe environment in north.

Description

technical field [0001] The invention relates to the technical field of liquid level measurement, in particular to a liquid level measurement device for tank trucks in oil well fracturing operations. Background technique [0002] With the deepening of deep wells and shale gas development in oil fields, construction operations have developed towards high pressure and large-scale development. The measurement of fracturing parameters is a key link in the production of oil wells. The normal operation of the measurement system is directly related to the progress of the project and construction safety. . [0003] The oil well fracturing project requires a variety of vehicles and equipment to participate in field operations. The tank truck driver who participates in the operation must timely grasp the liquid state and liquid level in the tank and need to go to the top of the tank to observe the liquid level in the tank. However, there are personal risks for the driver to climb up a...
