Automation Encyclopedia-the development history of flow meters
Flow meters have a wide range of applications in the automation industry, for the measurement of various media such as water, oil, and gas. Today, I will introduce the development history of flow meters. In 1738, Daniel Bernoulli used the differential pressure method to measure water flow based ...Read more -
Automation Encyclopedia-Absolute Error, Relative Error, Reference Error
In the parameters of some instruments, we often see accuracy of 1% FS or 0.5 grade. Do you know the meaning of these values? Today I will introduce the absolute error, relative error, and reference error. Absolute errorThe difference between the measurement result and the true value, that is, ab...Read more -
Introduction of Conductivity meter
What principle knowledge should be mastered during the use of the conductivity meter? First, in order to avoid electrode polarization, the meter generates a highly stable sine wave signal and applies it to the electrode. The current flowing through the electrode is proportional to the conductivit...Read more -
How to choose the Level Transmitter?
Introduction Liquid level measuring transmitter is an instrument that provides continuous liquid level measurement. It can be used to determine the level of liquid or bulk solids at a specific time. It can measure the liquid level of media such as water, viscous fluids and fuels, or dry media s...Read more -
How to Calibrate a Flowmeter
Flowmeter is a kind of test equipment used to measure the flow of process fluid and gas in industrial plants and facilities. Common flowmeters are electromagnetic flowmeter, mass flowmeter, turbine flowmeter, vortex flowmeter, orifice flowmeter, Ultrasonic flowmeter. Flow rate refers to the spee...Read more -

Flow rate is a commonly used process control parameter in industrial production processes. Currently, there are approximately more than 100 different flow meters on the market. How should users choose products with higher performance and price? Today, we will take everyone to understand the perfo...Read more -
Introduction of single flange and double flange differential pressure level gauge
In the process of industrial production and manufacturing, some of the tanks measured are easy to crystallize, highly viscous, extremely corrosive, and easy to solidify. Single and double flange differential pressure transmitters are often used in these occasions. , Such as: tanks, towers, kettle...Read more -
Types of pressure transmitters
Simple self-introduction of pressure transmitter As a pressure sensor whose output is a standard signal, a pressure transmitter is an instrument that accepts a pressure variable and converts it into a standard output signal in proportion. It can convert the physical pressure parameters of gas, li...Read more
