Calibration of magnetic flap level gauges To calibrate a magnetic flap level gauge, close the inlet and outlet valves of the float cylinder, drain any remaining liquid from the cylinder, and then bring a magnet close to the float rod while moving it from bottom to top; this completes the calibration process. There are impurities and slag in the tube, and a strong magnetic field exists around it. 2. Installation and use of magnetic flap level gauges: 1. This product must be installed vertically, with a maximum deviation of ≤3°. 2. There should be no ferromagnetic materials within 200 mm around the gauge body. 3. If the length of this product exceeds 4 meters, intermediate supports must be added during installation. 4. After installation, adjust the magnets by moving them slowly along the surface of the flaps, ensuring that the red side of all flaps faces the observer. 5. Before putting the level gauge into operation, the upper valve should be opened first, followed by slowly opening the lower valve, so that the medium can flow into the tank gradually, allowing the flap to turn one by one to reflect the level. And adjust the zero liquid level using the adjustment screw. 6. During use, if individual flaps fail to function due to sudden changes in liquid level or other reasons, it is possible to correct this by adjusting the magnets. 7. Before performing a pressure test on the container, please close the valve connecting it to the level gauge. 3. Maintenance of magnetic flap level gauges: After long-term use, if there are deposits of medium inside the gauge body, it can affect the proper functioning of the float; therefore, regular cleaning is necessary. Before cleaning, first close the gas-liquid phase valves to remove any remaining substances from within the cylinder. After cleaning, assemble it as before; reverse the position of the float, replace the gasket to prevent leakage due to aging, and tighten the screws.
I’ve learned something, thank you! It would be better if it were more detailed!
Reply to 2# big_fire: This is just one method to address the drifting of magnetic flip values
It can be calibrated while undergoing maintenance and upkeep. Since the flange opening has been removed during maintenance, the float can be placed inside first; then a wooden stick can be used to move the float up and down, simulating changes in liquid level. This allows one to check whether the float has sufficient magnetism and whether the flap moves smoothly.
Every step in the production of magnetic flap level gauges must be carried out with care and attention, paying close attention to every detail during manufacturing. Production must be conducted strictly in accordance with the established procedures, and thorough tuning is required to ensure that the products have reliable quality and can operate stably over the long term.
