Ultrasonic level gauge is a non-contact, high reliability, cost-effective, easy to install and maintain level measurement instrument. It can meet most of the level measurement requirements without touching the medium. It has a new signal processing technology, which is safe, clean, high precision, long life, stable and reliable, easy to install and maintain, simple reading and so on. It is widely used in petroleum, Chemical, water treatment, water conservancy, steel, coal, electric power and food processing industries, such as acid, alkali, salt, anti-corrosion, high temperature, explosion-proof and other fields. Ultrasonic level gauge installation operation guide: 1. The magnetic permeability of the ultrasonic level gauge is not allowed to be close to the body, and the wire is fixed. Otherwise, the normal operation of the ultrasonic level gauge will be affected. 2. If the user uses the heating circuit by himself, he must use non-magnetic materials, such as copper tubes. The heat tracing temperature is determined according to the medium condition; 3. The installation of the ultrasonic level gauge must be vertical. The ball valve should be installed between the ultrasonic level gauge and the container guide tube for easy maintenance and cleaning; 4. The medium should not contain solid impurities or magnetic substances to avoid jamming the float; 5. Before use, the ball below the zero position should be set to red with the correct magnetic steel, and the other balls should be set to white; 6. Open the bottom flange and insert the magnetic float (note: the heavy end has a magnetic end that is up and cannot be flipped. 7. When commissioning, first open the upper pilot valve, then slowly open the lower valve to allow the medium to smoothly enter the main conduit (the medium should avoid the rapid impact of the float during operation, causing the float to fluctuate and affect the display accuracy). Observe the magnetic red and white ball. Whether the flipping is normal, then close the lower pilot valve, open the drain valve, and let the liquid level in the main conduit drop. According to this method, it is normal, and it can be put into operation (except for special liquids such as corrosive); 8. The main conduit should be cleaned from time to time to remove impurities according to the medium; 9. For liquid level gauges exceeding a certain length (common type > 3 meters, anti-corrosion type > 2 meters), it is necessary to increase the intermediate reinforcement flange or ear climbing as a fixed support to increase the strength and overcome its own weight; 10. The installation position of the ultrasonic level gauge should be avoided or away from the inlet and outlet of the material medium to avoid rapid changes in the local area of ​​the material fluid and affect the accuracy of the liquid level measurement.
