one Magnetic level gauge There should be no magnetic chemical substances close to it. It is forbidden to use fine wire to fix it. Otherwise, it will endanger the normal operation of the magnetic flap level gauge;
2. If the customer chooses the heat tracing pipeline independently, it is necessary to use non magnetic conductive raw materials, such as copper pipe. The electric heat tracing temperature depends on the material condition;
three Magnetic level gauge The installation must be vertical. There should be a gate valve between the magnetic flap level gauge and the vessel lead pipe, which is convenient for maintenance and cleaning;
4. There should be no solid residue or magnetic chemical substance in the material to prevent the floating ball from sticking;
5. Before application, the calibration magnetic tile should be added, and the ball below zero should be set to bright red, and other balls should be set to milky white;
6. Open the bottom flange and install the magnetic levitation ball (Note: the heavy end with magnetic end and the end upward, do not install upside down.)
7. In the process of adjustment, first open the upper pilot gate valve, and then slowly open the lower gate valve, so that the material can stably enter the core pipe (during the operation, the material should be prevented from rapidly impacting the floating ball, causing the floating ball to fluctuate violently, and the accuracy of the information displayed), observe whether the rotation of the magnetic white red ball is normal, then close the gate valve of the lower lead pipe, open the filter valve, and let the liquid level meter in the core pipe lower, In this way, after three times of actual operation, if everything is normal, funds can be put into operation (except for unique liquids such as corrosion);
8. According to the material situation, the core pipe should be cleaned regularly to eliminate the residue;
9. For the liquid level transmitter beyond a certain length (general type > 3M, anti-corrosion type > 2m), it is necessary to lift the center structure, reinforce the flange plate or lug as the fixed fixed support point, so as to enhance the compressive strength and get rid of its net weight;
ten Magnetic level gauge The import and export of raw materials should be avoided by accurate measurement;
11. When the instrument panel of remote transmission supporting facilities is installed, the following shall be ensured:
a) The instrument panel of remote transmission supporting facilities shall be close to the core pipe of liquid level transmitter and fixed with stainless steel plate hoop (iron system is prohibited);
b) The magnetic induction surface on the instrument panel of remote transmission supporting facilities should face and close to the core tube;
c) The zero position of instrument panel of remote transmission supporting facilities shall be in the same horizontal line with the zero mark of liquid level transmitter;
d) The wiring between the instrument panel of remote transmission facilities and digital display instrument or industrial control computer is better, which is laid independently through the maintenance pipe or laid with shielded two core cable;
e) After laying the three-phase and five wire holes of the terminal block, it is required that the sealing performance is good to prevent the invasion of precipitation and moisture, so that the instrument panel of remote supporting facilities can not work normally. The terminal should be covered immediately after maintenance or adjustment.
