A detection method and detection system of a rotary magnetic float level gauge

Abstract

The invention discloses a detection method and a detection system of a rotary magnetic floating ball liquid level gauge. The sensor measures the resistance F in the direction of rotation of the liquid level gauge float in real time β Measure the rotation angle β of the floating ball in real time with the angle sensor; construct the determination curve of the rotation angle β and the resistance of the floating ball; the measured resistance value F β Compare with the judgment curve; compare the rotation angle β with the indicated value of the pointer of the liquid level gauge. The beneficial effects are: because the rotating rod rotates at a constant speed, the pressure sensor can accurately measure the resistance in the direction of rotation of the liquid level gauge in real time, which is convenient for judging the use performance and ensuring the measurement speed and accuracy; the angle sensor can measure the floating ball rotation angle and read the liquid level The measured data is transmitted to the information processor for processing, and the detected data is displayed through the display instrument to determine whether the difference meets the accuracy requirements.

Description

technical field [0001] The invention relates to a liquid level gauge, in particular to a detection method and a detection system for a rotary magnetic floating ball liquid level gauge for an automobile tanker. Background technique [0002] There are multiple safety assessment indicators for tank cars used for liquefied gas transportation. The liquid level gauge is one of the three safety accessories for tank cars. When the tank car is filled with medium, the liquid level gauge measures and displays the liquid level to prevent excessive installed to ensure safe and reliable sealing. Rotary magnetic float level gauge for liquefied gas tanker. Its working principle is that when the container is filled or discharged with the measured medium, the stainless steel float rises or falls with the change of the liquid level, driving the transmission shaft to rotate, and the connected Under the action of magnetic coupling, the magnetic steel makes the pointer installed in the flange se...

Problems solved by technology

The problem is that the detection method of the water tank is stable, but the detection medium is water. When the densities of the two media are different, the adjustment of the specific gravity before the detection and the correction of the detection results are cumbersome, and there will be certain errors. to the designated location to complete

The problem is that factors such as manual operation strength and inconsistent operation methods will lead to misjudgment, resulting in inaccurate detection, and the rotation resistance of the liquid level gauge cannot be measured, and the requirements for adjustment and correction cannot be met.
