Flow meter

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

Vortex flowmeters are mainly used for flow measurement of industrial pipeline media, such as gas, liquid, steam and other media. How to judge the performance of vortex flowmeter? It can be reflected by several important indicators such as accuracy, reproducibility, sensitivity, response time, zero drift and range drift. The following is an introduction for you.

What is the difference between standard condition and operating condition? How to calculate the gas state? How to convert the standard flow rate to the operating flow rate? (I) The difference between standard conditions and working conditions Working conditions: flow rate under actual working conditions, unit: m³/h Standard conditions: flow rate under temperature of 20℃

1. What is Modbus RTU Modbus RTU (Remote Terminal Unit) is a variant of the Modbus communication protocol used for serial communication. It is a common industrial control system communication protocol, usually used to collect sensor data, control actuators, and monitor device status. Modbus RTU uses binary encoding and uses serial communication protocols (such as

Foreword The natural gas ultrasonic flow meter is an instrument that uses the characteristics of ultrasonic waves propagating in gas to measure gas flow. This flow meter is widely used in the field of natural gas. Its working principle and characteristics are as follows: Operating Principle The natural gas ultrasonic flowmeter measures gas flow by
