Flange level gauge_ Zero point adjustment of differential pressure liquid level transmitter is independently produced by Xi'an Huaheng Instrument Co., Ltd
Liquid level transmitter is a kind of transmitter commonly used in liquid level measurement in China. It has a simple structure and is easy to assemble,
When the liquid level transmitter is frozen in summer, the transmitter assembled outdoors must adopt anti freezing measures to prevent the liquid in the pressure tap from compressing due to the frozen volume and leading to the sensor damage. When wiring, put the cable through the waterproof comment debate (accessory) or winding pipe and tighten the sealing nut to prevent the rain water and other cables from leaking into the transmitter shell.
Flange level gauge_ In the process of pressure transmission of differential pressure level transmitter, the possible causes of error are as follows:
2. Wear loss (especially for detergent);
3. There is gas in the liquid pipeline (causing pressure head error);
4. There is liquid in the gas pipeline (causing head error);
5. The density caused by the temperature difference between the pressure pipes on both sides is different (causing head error).
Type selection sample of liquid level transmitter manufacturer to determine flange standard, flange size, flange pressure level and flange form. Many are DIN standards and ANSI standards. Based on the principle that the static pressure of the liquid measured is directly proportional to the height of the liquid, the input liquid level transmitter adopts the piezoresistive effect of evacuated silicon or ceramic sensitive elements to turn the static pressure into the electric flag light. After temperature compensation and linear correction. Convert to 4-20madc standard current flag light output.
