Flow meter

There are two forms of voltage and current changes when they are transmitted through wires, which we call “common mode” and “differential mode”. The power line of the equipment, the communication line of the telephone, and the communication line that exchanges with other equipment or peripherals have at least two wires. These two wires are […]

In industrial settings, differential pressure flow meters are essential for accurate measurement and process control. However, cases of no indication often arise, even when other equipment seems to be functioning normally. This article will analyze two case studies to uncover common issues and solutions, followed by a comprehensive guide to troubleshooting and maintenance. Case Study

The grounding of instrumentation system is divided into protective grounding and working grounding. I. Protective grounding Methods of protective grounding: The field instrument bridge and threading pipe should be connected to the grounded metal components with grounding wires every 30m. It should be pointed out in particular that the field grounding of instruments and meters

Orifice plates are widely used devices for flow measurement and filtration across various industries. Depending on the specific requirements and application scenarios, there are several types of orifice plates. Below is a detailed explanation of these types, including their design characteristics, applications, and advantages. 1. Concentric Orifice Plate Description: The concentric orifice plate is the

1. Checking In order to timely discover possible defects or hidden dangers in equipment and devices, the corresponding responsible personnel shall refer to the equipment inspection (or patrol inspection) standards to conduct regular or irregular observation, inspection, and record of the equipment and devices under their jurisdiction. Note 1: In order to respect the development

A correctly installed orifice plate should have the constriction facing the direction of the fluid. The fluid contracts locally at the throttling center, increasing the flow rate and reducing the static pressure, so a static pressure difference is generated before and after the orifice plate, and this pressure difference has a certain functional relationship with

Vortex flowmeters are widely used in various industries due to their reliability and versatility. However, during operation, interference signals can affect measurement accuracy. This article analyzes the common sources of interference and provides detailed solutions to mitigate or eliminate their impact. Common Sources of Interference Fluid Fluctuations The presence of bubbles, suspended particles, or other

What is CODESYS Industrial Computer CODESYS industrial computer is an industrial control system based on the CODESYS software platform. CODESYS is an open and scalable automation software development platform that supports the IEC 61131-3 international standard programming language, enabling engineers to develop and maintain control systems in an integrated environment. CODESYS industrial computer combines this

Proper grounding of a mass flow meter is essential for ensuring its accuracy, safety, and longevity. While some may view grounding as a minor detail, neglecting this step can lead to significant issues, including measurement inaccuracies, equipment damage, and safety risks. Below, we will explore why grounding is necessary, the benefits it provides, and how

Process instruments are devices used in the field of industrial automation to measure and control process variables (such as temperature, pressure, liquid level, flow, etc.). In process control systems, sensors or transmitters communicate with the control system through electrical signals, and this communication method is usually divided into two-wire, three-wire and four-wire systems. These three
