Put-in hydrostatic level gauge principle: The input hydrostatic level gauge is a pressure sensor for measuring the liquid level. The hydrostatic level gauge is based on the principle that the measured hydrostatic pressure is proportional to the height of the liquid. It adopts foreign advanced isolated diffusion silicon sensitive components or ceramic capacitive pressure sensitive sensors to convert static pressure into electrical signals and then through the temperature Compensation and linear correction, converted into standard electrical signals. Put-in static pressure level gauge Scope of application:    Hydrostatic level gauge (level gauge) is suitable for liquid level measurement of various media in petrochemical, metallurgy, electric power, pharmaceutical, water supply and drainage, environmental protection systems and industries. The exquisite structure, simple adjustment and flexible installation provide users with ease of use. The standard signal output modes such as 4 to 20mA , 0 to 5v , and 0 to 10mA are optional by the user according to their needs. Maintenance measures after purchase of level gauge: Clean it once every month. 2) When cleaning, turn on the cap of the input-level water meter iron pipe and carefully take out the level gauge; then remove the attached debris ( such as water grass, plankton, etc. ) from the level gauge. 3) When cleaning the water level gauge to press the hole, you can use trichloroethylene or alcohol injection pressure hole to soak at the height of one-half for about 5 minutes, and then slightly shaken and repeated several times until it is cleaned. It is forbidden to use any appliance to clean the pressure hole, so as not to damage the sensitive core pressure diaphragm. 4) When cleaning the pressure port and pressure hole of the transmitter, avoid excessive hardness brushes or metal tools to avoid damage to the sensitive core and the pressure interface threads. 5) After the cleaning is completed, slowly return the level gauge to the iron pipe, feel that the lower part of the pipe has been placed, and install the cap back into place. After reinstalling after cleaning, due to certain changes in the installation depth, the water level indicator at the same level as the sluice must be used again to correct the detected value of the secondary instrument to ensure the correctness of the sampled data.
