With the rapid development of environmental protection sewage treatment industry in recent years, the demand for liquid level meter is also increasing. In the past, static pressure liquid level meter was used in sewage treatment, water tank and water tank radar liquid Position meter It will be widely used in the field of environmental protection, especially in the measurement of mud level and mud water stratification.
The application of liquid level gauge is very different, so it has many kinds.
At present, the pressure or differential pressure transmitter is still the main method to detect the liquid level of all kinds of tower and kettle in the production process. In addition to its high cost performance, there are some other advantages. For example: design, application habits. There are also float type and capacitance type. With the development of technology, the use of magnetostrictive, ultrasonic and radar level meters will increase rapidly, and the proportion of pressure (differential pressure) level meters will decrease.
Due to the large volume of tank farm storage tank, high accuracy of liquid level gauge is required. In the past, most of the float steel belt level gauge, servo type and static pressure type liquid level gauge are used. However, neither the float steel belt type, servo type or static pressure type liquid level gauge is the best way to measure the tank level in the tank farm. Due to the high accuracy of the hydrostatic level gauge and the high price of the static pressure gauge, the problem of the high reliability of the hydrostatic level gauge is inevitable due to the high cost of the static pressure gauge and the steel belt gauge.
Since the 1990s, the level gauge has become the first choice in the tank farm due to its high reliability and high reliability.
With China's domestic production Radar fluid position meter The development trend of radar level gauge is simple installation, high quality and low price. It will occupy a place in the application of tank farm.
