The main role of capillaries in pressure measurement or differential pressure measurement is to transmit pressure over long distances and to help protect sensitive pressure transmitters or sensors from high temperatures, corrosive media or vibrations in the measuring environment. Capillaries are ...
Five categories of stainless steel Austenitic stainless steel. These are the most commonly used types of stainless steel. Compared with other alloy steels, austenitic stainless steels tend to have a higher chromium content and therefore higher corrosion resistance. Another common feature of ...
In applications where hydrogen is measured, pressure transmitters or differential pressure transmitters usually use stainless steel diaphragms. However, when handling and measuring hydrogen, it is common practice to gold-plate stainless steel diaphragms. The reason behind this involves the ...
When the pressure transmitter is used to measure oxygen, it needs to be deoiled and degreased, because the characteristics of oxygen make it dangerous to react with organic matter such as grease in some cases, and even cause an explosion. The reasons and scenarios for this process are explained in ...
The drop type liquid level gauge is a sensor used to measure the height of liquid, especially suitable for various liquid storage tanks, rivers, reservoirs and other occasions. It determines the level height by measuring the static pressure of the liquid. The detailed explanation of the working ...
The signal output types commonly used by sensors in level switches generally have the following five types: Relay output, two-wire output, transistor output, non-contact output and NAMUR output, of which the relay output is the most widely used, transistor output and non-contact output are rarely ...
Process flow detection features In order to ensure the material balance in on-line flow production, it is necessary to detect and control the flow of fluid in the pipeline. This process flow detection has some distinct characteristics, because the production is continuous, subject to the fluctuation...
Vortex flowmeter is a common flow measurement equipment, widely used in industrial processes to measure the flow of gas, liquid and steam. The following is a detailed explanation of its working principle, structure, operating conditions, possible problems, temperature and pressure compensation and ...
Electromagnetic flowmeter is a common industrial flow measurement equipment, and its installation requirements are strict, which is directly related to the accuracy and long-term stability of the measurement. The following is a detailed description of the installation requirements of the electromagn...
Ultrasonic flowmeter is an instrument that measures liquid or gas flow through ultrasonic technology. It works on the basis that the speed at which sound waves travel through a fluid changes depending on the direction and speed of the fluid flow. Ultrasonic flowmeter is widely used in industry, ...
In the field of chemical engineering, there is a requirement that the length of the bolt should not be too long or too short, and the flange bolt should be left with 2 to 3 wires. For this part of the requirements, this public number has a simple introduction, see: Basic knowledge - Why should the ...
Coriolis mass flowmeter is based on the Coriolis principle, so that the medium flows through the flow tube vibration, the sensor detects and analyzes the flow tube frequency, phase difference and amplitude changes, directly measure the current flow of the flow tube media quality, from the vibration ...
