Flow meter

The turbine flowmeter is a typical velocity flowmeter. It has the characteristics of high measurement accuracy, fast response and high pressure resistance, so it is increasingly used in industrial production. The turbine flowmeter works based on the principle of conservation of fluid momentum. The measured fluid pushes the turbine blades to rotate the turbine. Within […]

In the context of a flow meter, “E Ex iaⅡC T4” refers to the device’s classification according to international standards for electrical equipment used in explosive atmospheres. Here’s a breakdown of each part: E Ex: This indicates that the equipment is designed and certified for use in explosive atmospheres, following the European ATEX (Atmosphères Explosibles)

1. The Impact of Vortex Flow Meters on the Accumulation of Flow Surface in Vortex Generators If there are viscous particles in the measured fluid, they may gradually accumulate on the upstream surface of the vortex generator, causing its geometry and size to change. As a result, the flow coefficient will also change accordingly. Therefore,

In industrial production, accurate measurement of steam flow is crucial for ensuring the stability and efficiency of the production process. Currently, the most commonly used methods for steam measurement are vortex flowmeters and differential pressure flowmeters. In practical applications, temperature and pressure compensation is an essential step to enhance the accuracy and reliability of these

The plastic insulation material and conductive components of terminal blocks are directly related to their quality, as they determine the terminal’s insulation and conductivity performance, respectively. Common faults of terminal blocks include: Loose Connections: Over time, connections may become loose due to vibrations, thermal cycling, or improper tightening during installation, leading to poor electrical contact.

Q: What is Faraday’s law of electromagnetic induction? A: When any conductor moves at right angles in a magnetic field, a voltage is induced in it, and this voltage is proportional to the speed of the conductor. Q: What is the Lorentz force? How do we get the electric field force? A: The force on

I. Common flange structure types 1. Slip-On Flange Characteristics: The Slip-On Flange is a type of flange connected to a vessel or pipeline using a fillet weld, also known as a lap joint flange. The connection between the Slip-On Flange and the pipe is achieved by first inserting the pipe into the flange bore to

Why do we need lightning protection grounding? For lightning protection of instruments and meters, we can use lightning protection modules. The grounding of lightning protection modules provides a discharge channel, which can quickly conduct and discharge lightning current when lightning strikes. The lightning protection module can only protect against lightning strikes after grounding.  Cable pipes,

The sensitivity of an instrument refers to the sensitivity of the instrument’s response to changes in the measured parameter, or the degree of amplification of the output of the measured parameter change. Sensitivity can be expressed as: Sensitivity (should be ε) = response change / measured change. It can be seen that sensitivity is actually

Signals are physical quantities that identify messages. For example, electrical signals can represent different messages through changes in amplitude, frequency, and phase. There are two types of electrical signals: analog signals and digital signals. Signals are tools for carrying messages and are the carriers of messages. In the process of using instruments, current signals, voltage
