What is the measuring principle of level gauge?

In everyday life, when we choose something, the first thing we do is to learn about it. The liquid level meter is no exception, before choosing to fully understand it, then understand its working principle is the first step, which is the most basic thing to do. Today, we make a simple science popularization on the measurement principle of several common liquid level meters, including radar level meters.

How to choose temperature transmitter?

The choice of temperature sensor is mainly based on the measurement range. When the measurement range is expected to be within the total range, a platinum resistance sensor can be selected. The narrower range usually requires the sensor to have a fairly high basic resistance in order to obtain a sufficiently large resistance change. The large enough resistance variation provided by thermistors makes these sensors ideal for narrow measurement ranges.

What is radar level gauge interference echo？

The measurement principle of the radar level meter is that the antenna receives the radar pulse reflected signal, and sends the reflected signal to the instrument, the microprocessor of the instrument analyzes the signal, and identifies the actual echo of the radar pulse signal on the surface of the material. When signal interference echoes happenes, what are the reasons for interference echoes?

What are the factors that affect the measurement accuracy of radar level meter

The radar level antenna transmits a narrow microwave pulse down through the antenna. After the microwave touches the surface of the measured medium, it is reflected back to be received by the antenna system again, and the signal is transmitted to the electronic circuit and automatically converted into the level signal. What are the factors that affect the measurement accuracy of radar level meter?

Why does the value of ultrasonic level meter fluctuate?

When the display value of ultrasonic level meter fluctuates, we can use the following methods to figure out the problem.

How to choose the radar level gauge?

At present, there are many types of radar level gauges on the market. Radar level gauges emit extremely short microwave pulses with very low energy and are transmitted and received through the antenna system. It has the advantages of stable performance, flexible use, high reliability, and easy maintenance. So when users choose radar level gauges, what factors should they pay attention to in order to choose a suitable radar level gauge? After reading the following 5 points, you will probably understand.

How to solve a fault in the guided wave radar level gauge

It is believed that many users have encountered reading fluctuations when using guided wave radar liquid level meters. Many users do not know how to solve it for a while, and some users even directly want to replace the instrument. This is really easy, but it will greatly increase the cost. We should analyze the cause of this situation, and then correct debugging can be solved

How to Install 80GHz Radar Level Gauge

Radar level meter can be widely used in liquid and solid level measurement. Continuous level measurement of various media, even under high pressure, corrosive, hygienic or harsh conditions. Radar level meter is divided into non-contact radar level meter and contact radar (guided wave) level meter according to the different measurement purpose, material characteristics and storage tank environment.

How to choose the lining material of magnetic flap level gauge tube?

As a kind of common liquid level measuring instrument, magnetic flap level gauge, because the measuring tube body is connected with the measured vessel, directly contact with the medium, therefore, the material of the tube body is good or bad for the service life of the magnetic flap level gauge has a direct impact.If you use stainless steel directly to measure some corrosive media, it is easy to be corroded and leakage, resulting in production accidents.

Classification and construction of float level meter

Float level gauge according to the float installed in different locations are also divided into two types of internal and external float, the so-called internal and external division refers to the float installation place, in the measured liquid container is the internal float, in the measured liquid outside the container is called external float.

Why does measuring steam require temperature and pressure compensation?

The specific volume of superheated steam is determined by the temperature and pressure of steam two parameters, and in different parameter ranges, the expression form of the specific volume is not the same, can not be expressed in the same general formula, so you can not get a unified formula for calculating the specific volume, can only be derived individually to find the temperature and pressure compensation metric.

Why does measuring steam require temperature and pressure compensation?

How radar level meter works better under large dust conditions!

With the development of modern industry, more and more industries need to measure and control the level of solid materials, such as cement, coal, powder, etc.. And in large dusty working conditions, traditional level meters are easily disturbed by dust, which leads to inaccurate measurement and affects production efficiency. Radar level meters, on the other hand, can work better by using special technology and materials to improve their ability to overcome dust interference.
