One of them is the top installation of the magnetic flap level gauge we are going to introduce today. First of all, do you know its principle, technical parameters and precautions during installation? If you are not sure, be sure to read the introduction of the editor todayTop mounting of magnetic flap level gauge1. Introduction to the top mounting of the magnetic flap level gaugeThe mh7120 level gauge is suitable for measuring all kinds of containers that are not convenient for side-mounted level gauges, especially underground storage tanks. Widely used in petroleum, chemical, metallurgy, electric power, light industry and other industries, medicine and other industries and departmentsTop mounting of magnetic flap level gauge2. The principle of top mounting of the magnetic flap level gauge1. Structural principle: the top-mounted magnetic flap level gauge is directly installed on the top of the container, the magnetic connecting rod moves up and down with the liquid level (or interface) through the floating ball, and the magnetic steel in the magnetic connecting rod is driven by the principle of magnetic coupling Magnetic flap indicator, red and blue (liquid red and gas blue) can be used to indicate the liquid level or boundary position in the process vessel, which can be automatically transmitted and controlled remotely. UHZ series top-mounted magnetic flap level gauge is mainly composed of the main body, on-site indicator, remote transmitter, upper and lower limit alarm, etc.2. Working principle: from the main body & 40; consists of upper and lower pipes, flap box (composed of red and white magnetic flaps), float (composed of magnet, ejector rod, and float), and liquid level transmitter. Its structure is shown in the figure, and the working principle is: the pontoon in the container (developed according to different media and pressure) floats up and down with the change of the liquid level in the down tube, and the magnet moves up and down in the upper tube through the ejector rod to make the outer flap rotate, using red and white Two colors indicate liquid level. At the same time, the liquid level transmitter transmits the liquid level signal to the control center for liquid level indication and control, which can also be monitored by a computerTop mounting of magnetic flap level gauge3.

There must be no solid impurities and magnetic debris in the cylinder of the level gauge, so as not to block the float and weaken the buoyancy; magnets are not allowed near the gas cylinder, otherwise it will directly affect the normal operation of the level gauge. After the level gauge is installed, it needs to be calibrated with magnetic steel. At this time, it will display white on zero and red below zero.Top mounting of magnetic flap level gauge, We must know what kind of tool the top installation of the magnetic flap level gauge is and why it has such a big impact on our work. If you have a need for this, you can go to Huikeda Instrument Co., Ltd. to have a look. I believe there will be the products you need
