The liquid level gauge is a kind of liquid level measuring instruments which is widely used in industrial field. It uses the principle of magnetic flap to monitor the liquid level and converts the liquid level signal into an electrical signal output. This type of liquid level meter has the characteristics of accuracy, reliability and stability, and is widely used in petroleum, chemical industry, manufacturing healing things, food and other industries.

Magnetic liquid level meter plays an important role in industrial production and process control due to its high precision, reliability and intelligence. This stable level measurement technology provides accurate data and automated operation for production processes in various industries, improving production efficiency and safety.

Guided wave radar level gauge is used in water and liquid storage tank, acid and alkali storage tank, slurry storage tank, solid particle, small oil storage tank. All kinds of conductive, non-conductive media, corrosive media. Such as coal bunker, ash bin, oil tank, acid tank and so on.

A pressure transmitter is an instrument used to measure the pressure of a liquid or gas, converting the pressure into an electrical output. Its function is to convert the pressure signal into a standard signal for easy processing and control in the automatic control system. In industrial production,china pressure transmitters are widely used in petrochemical, power, water treatment, pharmaceutical, food and other industries.

Differential pressure level gauges and radar level gauges are two different types of level gauges. Differential pressure level gauges (dp level gauge) measure the difference in pressure between the surface of the liquid and the bottom of the container to determine the liquid level.

Ultrasonic level meters and radar level meters are common level meters, and they can both be used to measure the height of liquids. But they work differently. The sondar ultrasonic level meter uses the time of ultrasonic wave propagation in the medium to measure the liquid level height, while the radar level meter uses the time of microwave propagation in the medium to measure the liquid level height.

Guided wave radar level gauge is used in water and liquid storage tank, acid and alkali storage tank, slurry storage tank, solid particle, small oil storage tank. All kinds of conductive, non-conductive media, corrosive media. Such as coal bunker, ash bin, oil tank, acid tank and so on.

Today, I will explain to you the principle of ultrasonic level meter​, what advantages and disadvantages it has.

The pressure transmitter is mainly composed of pressure sensor, measurement circuit and process connector. The physical pressure parameters such as gas and liquid sensed by the pressure sensor can be converted into standard electrical signals, which are provided to secondary instruments such as alarms, recorders and regulators for measurement, indication and process regulation. In China, the pressure transmitter used in small automation control is generally based on the piezoelectric resistance

Radar needs to be considered under the corrosion and adhesion of the medium working condition, in addition to the selection of too long guided wave radar antenna and equipment maintenance is also a need to think about the situation, intelligent radar, high frequency radar level meter can be exchanged, and guided wave radar because the length of the guide rod (cable) depends on the working condition, usually can not be exchanged, affected by this type of guided wave radar must be subject to certa

Liquid level measurement is an important link in process industry, involving production efficiency, product quality, safety and environmental protection. There are a variety of common liquid level measuring instruments on the market, of which 80GHz radar level meter and external level meter are two more popular non-contact measuring technologies. This paper introduces the working principle, technical characteristics, performance differences and application scenarios of these two instruments, ana
