Featured Radar Solid Level Sensors

Solid level measurement

A solid Level Sensor refers to an instrument that detects changes in the height of solid materials in containers in real-time. Level gauges are also called level transmitters, level controllers, level gauges, and level gauges.

Solid level measurement is widely used in modern industrial production, mainly to detect the height of materials in closed or open containers during industrial production.

Generally speaking, the continuous detection method of material height is called the continuous measurement method. The detection of material height reaching a certain position is called limit measurement method, or switch measurement method.

The instrument that is often used to measure and control the level of solids or liquids in storage tanks, tanks, etc. is called Solid Level Sensor.

Among them, the instrument specifically used to measure solids is also called Solid Level Sensor. The instrument specially used to measure liquid is called a liquid level sensor. Extended reading: Radar Level Meter for Corrosive Liquids

Solid level measurement

There are many types of Solid Level Sensors. This article will list the most common and commonly used types of level meters on the market today, and briefly introduce them to users.

Static pressure type level meter: used for level measurement in tanks or containers, can be installed directly or through remote sealing components.

Ultrasonic level meter: used for level monitoring of liquids and granular solids.

Radar level meter: small beam angle (minimum 5 degrees), energy concentration. Stronger anti-interference ability. Greatly improved measurement accuracy and reliability. Both solid dust and liquid can be monitored.

Capacitive level meter: level measurement under high temperature and high pressure conditions. Dustproof, anti-hanging material, anti-steam, anti-condensation. A new type of capacitive continuous level meter. Due to the use of radio frequency technology and microcomputer technology, it solves the problems of large temperature drift, difficult calibration and fear of adhesion of traditional capacitive level meters.

It can be widely used in continuous measurement of liquid and solid silo levels in various industries. Especially for measurement under high temperature, strong corrosion, strong adhesion, and dusty environment, the capacitive level meter is the most suitable.

Level switch: It is used to detect the predetermined liquid level of granular solids, slurries and interfaces. Ultrasonic method or high-sensitivity capacitive measurement.

Ultrasonic Level Sensor for Solids

The ultrasonic pulse emitted by the ultrasonic transducer is transmitted to the surface of the object to be measured through the propagation of coal qualification. After reflection, it returns to the receiving transducer through the sound transmission medium.

Measure the time that the ultrasonic pulse propagates in the sound transmission medium from the transmission to the reception. Then according to the speed of sound in the sound transmission medium, the distance from the transducer to the object surface can be calculated. To determine the level.


What are the different types of level sensors?

Types of Level Transmitters:
Level measurement transmitters are of seven types. Each type of transmitter works in a different way, and makes it useful for different types of processes.
Capacitance Level Transmitters
Hydrostatic Level Transmitters
Magnetic Level Transmitters
Radar Fill Level Transmitters
MUltrasonic Level Transmitter
Guided Microwave Level Transmitters
Hydrostatic level transmitters

What type of sensor is a fuel level sensor?

Regarding fuel level measurement, we can use contact and non-contact level sensors.
Contact types are: Magnetostrictive level transmitter is the most commonly used.
Non-contact type: Ultrasonic non-contact liquid level sensor is the most convenient.

How does a float level sensor work?

Float level sensor uses magnetic float as the measuring element. Through magnetic coupling, the internal resistance of the sensor changes linearly. The smart converter converts the resistance change into a 4-20mA standard current signal. It can display the percentage of liquid level, the current of 4 ~ 20mA and the value of liquid level. Remote transmission control room can realize automatic detection, control and recording of liquid level. This instrument is suitable for petroleum, chemical, power, light industry and pharmaceutical industries, such as sewage treatment and medium level measurement in various atmospheric and pressure vessels, especially for underground tanks and tanks.
