What is a level meter? What types of level gauges are there? Level measurement usually refers to the detection of the height of the material (solid or liquid level) in the closed or open container in the industrial production process. If the height of the material is continuously detected, it is called continuous measurement; if only the height of the material reaches The detection of a certain position is called limit measurement; the instrument that completes this measurement task is called a level gauge. Level meter classification Radar level meter Radar level meter adopts the measurement method of microwave pulse, and can be normal in the industrial frequency band, with low beam energy, and can be installed in various metal and non-metal containers or pipes. Non-contact continuous measurement of the level of slurries and pellets. It is suitable for occasions where dust, temperature and pressure change greatly and inert gas and steam exist. The radar level meter transmits and receives very short microwaves with very low power through the antenna system. Radar waves travel at the speed of light. The operating time can be converted into a level signal by means of electronic components. A special time extension method ensures stable and precise measurements in a very short period of time. The resistance level meter has the characteristics of high temperature resistance, accurate measurement results, strong anti-interference, etc. It also has super anti-shake performance, super dust-proof sealing performance and high cost performance. Some of the resistance level gauges are also called resistance level gauges or resistance level switches, resistance level switches, etc., which use an AC micro-motor to drive the detection blade to rotate slowly after deceleration. When the material level of the material to be measured rises and the rotation of the blade is blocked, the main shaft of the detection mechanism produces a rotational displacement. This displacement first makes a micro switch act to send out a material signal. Then another micro switch acts to cut off the power of the micro motor to stop the rotation. This state will remain as long as the material level in the bin remains unchanged. Tuning fork level meter The tuning fork level meter is not affected by foam, eddy current and gas, and is suitable for fixed-point alarm or control of the level of solid materials in various silos and liquid levels in various containers, and various models can be suitable for different occasions. application. The working principle of the tuning fork level meter is to make the tuning fork vibrate at a certain resonance frequency through a pair of piezoelectric crystals installed on the tuning fork base. When the tuning fork is in contact with the measured medium, the frequency and amplitude of the tuning fork will change, and these changes will be detected, processed and converted into a switching signal by the intelligent circuit. Therefore, the tuning fork level meter is not only suitable for solid materials, but also for the measurement of liquid media. Ultrasonic level meter Ultrasonic level meter is divided into many models according to the scope of application, such as anti-corrosion ultrasonic level meter, solid ultrasonic level meter, solid integrated ultrasonic level meter, etc. They have the functions of high precision, high stability, strong anti-interference ability, small launch angle, high transmission frequency, anti-overvoltage and anti-lightning strike. During the measurement process of the ultrasonic level meter, the signal sent by the ultrasonic probe is reflected by the surface of the liquid or solid material and then folded back, and received by the same probe to measure the entire running time of the ultrasonic wave, thereby realizing the measurement of the material level.
