Problem 1: Measurement fluctuations due to external disturbances When a company used radar level meters to measure maleic anhydride, it was found that one of them was showing small fluctuations. On examination, it was found that there was a low-power electric motor near the measuring tank. When the motor operated, the meter showed small fluctuations. […]

Many companies have experienced major or minor problems when using radar level meters for level measurement, most of which are related to installation. Therefore, it is necessary to know the following radar level meter installation tips. Tip 1: The radar level meter should be selected in a position that is easy to wire and easy

The basic measuring principle of the radar level meter is composed of transmitting, reflecting, and receiving. The antenna of the radar sensor emits the radar signal in the form of a beam, using the microwave pulse measurement method, with different distances corresponding to different levels. Generally speaking, microwave pulses are emitted at an interval of

In the field working conditions, we can see various liquid level meters, such as tuning fork vibration type, magnetic float type, pressure type, ultrasonic, sonar wave, magnetic flap, radar, etc. As the level meter is used to measure the liquid level of the vessel, it is difficult to install and the installation has to have

The high-temperature radar level meter is a radar level measuring instrument with a measuring distance of up to 30 meters. It can be used for the measurement of blast furnace levels, thick tank top storage tanks, short pipe installations, and other working conditions with an output power of 4…20mA analog signal. It uses the microwave

In the measurement industry, the ultrasonic level meter is a very practical instrument, which is mainly made of ABS and other related materials, has a good waterproof and explosion-proof effect, and the probability of failure of the ultrasonic level meter is very low. When measuring, it does not need to be in contact with the

The radar water level meter is widely used for water level monitoring in rivers, streams, seawater, and reservoirs. Its main advantage is that it is not affected by weather, temperature, wind speed, etc., and it does not need to touch the water, so it is not affected by the water body. Moreover, the measurement data

High-frequency microwave pulses issued by the guided wave radar propagate along detection components (steel cable or steel rod) and met the media to be measured, since the dielectric constant of the mutation, causes reflections, a portion of the pulse energy is reflected back. Transmit pulse and the reflected pulse is proportional to the distance and

A guided wave radar level meter is a measuring instrument based on the time domain reflection principle. The electromagnetic pulse of the radar level meter travels at the speed of light along a steel cable or probe. When encountering the surface of the measured medium, part of the radar level meter’s pulse is reflected to

At present, in the measurement industry, with the advantages of accurate measurement, safety and reliability, simple maintenance, and long service life, radar level meter firmly occupies a place, and is widely used in chemical, metallurgical, electric power, coal, and other industries, playing an extremely important role. Today share three radar-level meter debugging methods, so that
