Level measurement, which instrumentation is being used now?

Liquid level is the height of the liquid level in a sealed container (pool) or an open container (pool). In addition, liquid level measurement is divided into two categories: continuous measurement and level measurement.

Continuous measurement: continuous measurement of the liquid level changes, can realize the continuous measurement of the instrument has a level meter or level transmitter; level measurement: detect whether the liquid level reaches the upper limit, lower limit and so on a particular position is called level measurement instruments, can realize the level measurement of the instrument has a level switch. In water treatment, the use of liquid level of the upper, middle and lower level to control the lifting pump on or off and level alarm.

In daily life and industrial production and operation, often need to understand the liquid level in the container. Part of the situation is due to the tank is too large, people are not convenient to enter and tanks and other container materials are not permeable and other factors, this time the need for relevant instrumentation to help, then you know, liquid level measurement are where the instrumentation? 　　It is reported that the instrumentation to measure the liquid level is called liquid level meter. Liquid level meter for the level of a kind of instrumentation. Types of liquid level meters are tuning fork vibration type, magnetic floating type, pressure type, ultrasonic, sonar wave, magnetic flap, radar and so on.

In addition, pressure transmitter products are widely used in steel, chemical, paper, sewage treatment, water, heat, electricity, food, non-ferrous and other industries. In addition to measuring pressure, china pressure transmitters can also be derived from many uses, such as the use of differential pressure transmitters to measure flow, the use of gravity of the liquid to measure the level. 　　There is also the use of liquid level sensors. Liquid level sensor to the container level signal into a switch signal or voltage and current signal, and then through the external circuit, intuitively let the measurer accurately know the liquid level in the container. Liquid level sensor types are many and complicated, photoelectric level sensor with accurate measurement, high precision, fast response speed, advanced technology, low power consumption and other advantages in the liquid level sensor market occupies a unique advantage for liquid level measurement.

The development of science and technology to today, has produced countless kinds of liquid level measurement methods, from the ancient scale, the development of modern ultrasonic, radar measuring instrument. Liquid level measurement technology has also experienced a qualitative leap, the measurement of liquid level instrumentation is also a lot, do you know what are there?
