The anti-corrosion magnetic flap level gauge mainly uses the magnetic float as the measuring element, and the magnetic steel drives the display of the flip column without energy. Suitable for low temperature to high temperature, vacuum to high pressure and other environments. is stone
Ideal liquid level measurement products for industrial sectors such as oil and chemical industry.
The anti-corrosion magnetic flap liquid level gauge is equipped with upper and lower limit switch outputs, which can realize remote alarm and limit control. The anti-corrosion magnetic flap liquid level gauge is equipped with a transmitter, which can realize the long-distance indication of the liquid level.
display, detection and control. According to the different installation position in the container, there are two types of side loading and top loading. According to different working media, stainless steel and ABS engineering plastics are available. Among them, ABS is especially suitable for corrosive media such as acid and alkali.
1. Basic type
According to the principle of buoyancy, the float moves up and down with the rise and fall of the liquid level in the measuring tube, and the permanent magnet steel in the float drives the red and white flips through magnetic coupling.
When the column is flipped 180′, when the liquid level rises, the column turns from white to red, and when it falls, the column turns from red to white, so as to realize the indication of the liquid level.
2. Upper and lower limit switch output
Use the magnetic float to move with the liquid level to make the reed switch installed on the set position of the liquid level gauge standpipe act to realize on-off control or alarm.
3. Electric remote transmission
Install the transmitter on the anti-corrosion magnetic flap level gauge. The transmitter is composed of two parts: sensor and converter. It moves up and down through the magnetic float, and makes the measuring element in the conduit through the action of magnetic coupling.
The parts act in sequence to obtain the change of the resistance signal, and the standard current signal output of 0-10 or 4-20mA is summoned, so as to be connected with the digital display instrument or computer to realize remote display and control.
The anti-corrosion magnetic flap level gauge cannot be approached by magnetically conductive substances, nor can it be fixed with iron wires, because the above operations will affect the normal operation of the magnetic flap level gauge.
The magnetic flap level gauge must be installed vertically, because a ball valve should be installed between the magnetic flap level gauge and the container lead pipe for maintenance and cleaning.
When opening the bottom flange of the magnetic flap level gauge, a magnetic float should be installed. Here, the user is reminded to pay attention to prevent the heavy end with the magnetic end upwards and cannot be flipped upside down. And for liquid level gauges that exceed a certain length, it is necessary to increase the middle and reinforce flanges or lugs as fixed support points, so as to increase the strength and overcome its own weight.
When debugging the magnetic flap level gauge, you should first open the upper lead pipe valve, and then slowly open the lower valve, so that the medium can enter the main pipe smoothly, and then observe the magnetic red.
White ball flip is not able to operate normally. Then close the downpipe valve, and let the liquid level in the main pipe drop when the blowdown valve is opened. According to this method three times, it is normal If so, it can be put into operation.
