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.

With the development of RF level detection technology, capacitive products have gradually developed into conductive products, which can be used to measure the level of media in containers under different working conditions. However, from the communication with users, many users still know little about the principle of RF Admittance and RF Admittance level switch, and they do not know how to select the correct type.

The mini tuning fork switch, also known as the compact tuning fork level switch, is relative to the tuning fork level switch. At present, small tuning fork switches mainly include compact tuning fork level switches and high-temperature compact tuning fork level switches. So why develop small tuning fork switch when there is tuning fork switch​?

"Wire system" is a term often encountered in the automation industry, referring to the number of emergency pull-wire switches​ used for instrument power supply and standard signal transmission. The title of multi-wire system came into being after the birth of two-wire transmitter. So, what is the two-tier system? What are its advantages?
