Installation and use of glass tube liquid level gauge

What should be paid attention to when installing the glass tube liquid level gauge? Precautions for installation and use of the glass tube liquid level gauge: 1. Before installing the glass tube liquid level gauge, the box should be carefully disassembled to prevent breaking the glass. Do not knock the glass tube liquid level gauge body too heavily during installation. Do not have excessive vibration. 2. After the glass tube liquid level gauge is installed, when the medium temperature is very high, do not open the valve immediately, it should be preheated for 20-30 minutes, and then slowly open the valve after the glass tube has a certain temperature. When the valve is opened, first open the upper valve slowly, and then slowly open the lower valve, so that the measured medium slowly enters the glass tube. 3. When the glass tube liquid level gauge is in use, the dirt on the inner and outer walls of the glass tube should be cleaned regularly to keep the liquid level display clear. When cleaning, first close the upper and lower valves connected to the container, open the drain valve, drain the residual liquid in the glass tube, use an appropriate cleaning agent or use a long rod brush to wipe away the dirt on the inner wall of the tube. 4. If the quartz tube is broken or the scale is serious and needs to be replaced, first remove the lower body, unscrew the nuts and nuts at both ends, tap the quartz glass tube from one end to the other with a wooden stick, take out the graphite ring, and place the new Install the quartz tube, then put the graphite ring on the quartz tube, and insert it into the watch body at equal distances. Tighten the nuts and nuts at both ends. After confirming that there is no leakage, it can be put into operation. Glass tube liquid level gauge is a commonly used contact type liquid level gauge, which has the advantages of simple structure, accurate and easy-to-read measurement, etc. However, it also has defects such as being fragile and prone to mechanical failure. Such as flammable, explosive, strong corrosion, strong acid and other media measurement is not suitable for measuring with glass tube level gauge. The externally attached liquid level gauge is a non-contact liquid level gauge. It uses the principle of sonar distance measurement to measure the liquid level. The ultrasonic magnetic probe can be attached to the bottom of the container to measure. It can be suitable for various high temperature and high pressure airtight. Liquid level measurement of various flammable, explosive, toxic substances, strong acids, strong alkalis and various pure liquids in containers.
