Introduction of magnetic level gauge

 1.jpg The magnetic flap level gauge is a key instrument for liquid level measurement It is a liquid level indicator with two-color magnetic turnover column with a magnetic ball controller. It can be used to detect the chemical level indicator of various mechanical equipment such as towers, tanks, tanks, spherical vessels and heat treatment furnaces. Therefore, according to this design concept, it is relatively popular to master its basic principle: when magnetic turnover column liquid level transmitter accurately measures liquid, it adopts top mounting or inlet valve tube side mounting mode. The main body of the magnetic turnover column is refitted with a liquid level indicator and a floating ball liquid level meter Liquid level transmitter The magnetic control module is placed inside the centrifugal pump pressure controller or connected with the centrifugal pump pressure controller according to the small chain. When the centrifugal pump pressure controller is connected to the magnetic control module and changes with the liquid level display, the magnetic pattern (magnetic flap hook) will rotate; the liquid level gauge with magnetic floating ball will be in accordance with the liquid structure domain attitude; in addition, the water level sensor will work with magnetism in the centrifugal pump pressure controller In use, the standard variable resistance signal is output, and then through the intelligent transmitter, the resistance signal is converted into 4 ~ 50 Ma total electric flow signal output.

The application of the magnetic flap level gauge follows the basic law of floating ball and magnetic principle, and must be connected with the storage tank according to the flange plate. In the whole process of accurate measurement, the two-color column magnetic levitation ball inside the machine and equipment will change under the harm of electromagnetic field, and the joint of floating ball is the specific level meter of storage tank. In the whole process of installing machinery and equipment, it is necessary to prevent magnetic conductive chemicals around the machine and equipment, and determine the electric heat tracing temperature according to the material conditions. In the case of large connection of gas high efficiency liquid phase drilling, flange plate must be installed in the middle of Sanchang liquid level transmitter. In the whole process of machine equipment adjustment, magnetic tile orthodontic appliance must be used to adjust the magnetic column to milky white, and then open the liquid phase stop valve and high-performance liquid phase stop valve in turn, and observe the level meter elevator.

When the level meter lift in the measured vessel, Liquid level transmitter The magnetic levitation ball in the tube is also along with the elevator. The rare earth permanent magnetic steel in the floating ball is transferred to the magnetic column indicator according to the magnetic coupling, and the red and white turnover column is rotated. When the liquid level meter rises, the turnover column changes from milky white to bright red, when the liquid level meter decreases, the turnover column changes from bright red to milky white. The intersection of white and red of indicator is the specific height width ratio of liquid level meter inside the vessel, and then the end The liquid level meter shall be clearly marked.
It can ensure high sealing, anti leakage and suitable for high temperature, high pressure and anti-corrosion places. It has more advantages for high temperature, high pressure, toxic, hazardous and strong etching materials. In direct contact with the material, the sealing requirements of the pressure switch of the water pump should be strict, and the viscous substance can not be accurately measured. Permanent magnetic materials are easy to be demagnetized Liquid level transmitter The middle pass is not working properly, so the hook can not be turned over easily. If the permanent magnetic material is demagnetized, the liquid level transmitter can not work normally.
