The antenna is the eye of the radar level meter, and the shape of the antenna must be suitable for the physical properties of the electromagnetic wave. The shape of the antenna determines the focus and sensitivity of the radar wave, just like the sensitivity of a microphone.

High quality instrumentation will undoubtedly significantly improve the reliability and stability of measurement and control, but in the process of daily use, if you can consciously strengthen the safety management of the instrument, it will make the instrument better used for level measurement and control, while also extending the service life of the instrument. So, how to do a good job in the safety management of instruments and meters?

Different working conditions and different measuring media have led to the development of a wide variety of level measuring instruments. There are different classifications of level measuring instruments according to different instruments. In this paper, we mainly talk about the categories of level measurement instruments​ from two aspects, namely, measurement mode and measurement method.

How about determining whether instrumentation in industry meets the requirements for explosion protection? This is a worthwhile learning point for users who need to use explosion-proof products or for partners who need to know about level instruments. The following Kaidi Energy Technology Co., Ltd. to introduce you to the relevant aspects of knowledge points!

RF Admittance Level Switch is a common level measurement switch with wide application, mainly used for the level measurement of plastic, feed, grain, rubber, medicine, sand, food, cement, paint, clothing, pulp and other materials. When it comes to RF Admittance level switch, many people will question: What is the difference between RF Admittance level switch and radar level meter?

What are the common failures and solutions of float level meter? This paper mainly discusses this issue.

Industrial production often use transmitters, such as pressure transmitters, temperature transmitters, liquid level transmitters, etc., but the standard signal of these transmitter class is clear? Pressure transmitter class standard signal transmission why is 4 ~ 20mA, rather than 0 ~ 20mA?

In the process of burning coal in thermal power plants, a large amount of coal ash is generated. This coal ash is usually collected in coal ash bins and coal ash hoppers. In order to avoid the stored coal ash from bubbling up the tank, it is quite necessary to detect and control the height of the coal ash material level.

Ultrasonic transducer, also known as ultrasonic probe, is a key component of the ultrasonic level meter, and it is not too much to say that it is the "heart" of the ultrasonic level meter. The ultrasonic transducer converts high-frequency high-voltage power into high-frequency mechanical vibration, and the maximum power output can reach several kilowatts, so the stability and power output of the ultrasonic transducer plays a very important role in the performance of the ultrasonic level transmit

Liquid level alarm switch is widely used in water conservancy, chemical, environmental protection, food and pharmaceutical industries, etc. It is a liquid level measuring instrument specially designed for vessels, tanks and various pipelines.

The guided wave radar level meter has a different working principle compared to other radar level meters and has its own advantages and shortcomings. It is very important for users, especially purchasers, to know this information for proper selection. Below, the principle and advantages and disadvantages of the guide wave radar level meter are described below.
