Flow meter

Multiphase flow measurement is a critical technology used in industries where fluids consisting of different phases (such as gas, liquid, and solid) are transported together through pipelines. This is particularly important in the oil and gas industry, where water, oil, and gas often co-exist in extraction and production processes. Accurately measuring the flow rates of […]

1. Pre-Maintenance Preparation 1.1 Safety Authorization and Site Control Operational Coordination:Coordinate with the process control department to obtain written work permits and clearly define operational adjustments during maintenance. Ensure that maintenance work does not affect safe system operation. Confined Space Entry (CSE) Preparation:For meters installed underground, open the manhole cover and ventilate the space for

The risk of dust explosions is a critical concern in industries where materials such as flour, wood, metal, or plastic powders are processed or handled. Many substances that may seem harmless can create explosive dust clouds under the right conditions. Properly identifying and assessing the combustible properties of dust in a facility is essential to

In industries such as chemical processing, water treatment, energy, and food manufacturing, liquid flow measurement is a critical part of process automation. However, liquid media can vary greatly in properties—such as conductivity, viscosity, purity, or corrosiveness—so selecting the right flowmeter requires a comprehensive understanding of both the fluid and the working conditions. This guide provides

Coriolis mass flowmeters have become a cornerstone in precision flow measurement. While turbine and positive displacement (PD) flowmeters have long dominated applications demanding high repeatability and accuracy, Coriolis technology represents a significant leap forward—particularly in complex or harsh process environments. 1. Working Principle of Coriolis Mass Flowmeters Coriolis flowmeters measure mass flow directly using the

Correct installation of orifice plate flowmeters is crucial to ensuring measurement accuracy and long-term stable operation. The following sections provide a detailed procedure and key considerations for installation. 1. Pre-Installation Preparation 1.1 Verify Specifications and Model Selection Confirm that the orifice plate’s specifications (e.g., nominal diameter, pressure rating, bore size, flow direction mark) meet the

Electromagnetic flowmeters are widely used in industrial flow measurement for their accuracy, stability, and versatility. Understanding their operating principles, common issues, and best practices for installation and maintenance is essential for field engineers and maintenance professionals. This article provides a comprehensive overview based on real-world troubleshooting and frequently asked questions. 1. Working Principle of Electromagnetic

Background A combined heat and power (CHP) plant in Jiangsu Province is undergoing comprehensive upgrades to enhance boiler efficiency and optimize operations as part of its smart plant initiative. Given the complex and variable composition of the coal used, the plant must comply with the Water Pollution Prevention and Control Action Plan and the Pollutant

1. Basic Principle Vortex flow meters operate based on the Kármán Vortex Street principle. When a fluid flows past a bluff body (called a vortex shedder), alternating vortices are formed downstream, and the frequency of these vortices is proportional to the fluid velocity. 2. Instrument Coefficient (K Factor) The K factor, or instrument constant, indicates

Electromagnetic flow meters are widely used in various industries for their accuracy and reliability. However, in applications involving contaminated or chemically active fluids, inner wall fouling and electrode scaling can affect measurement accuracy and device lifespan. This guide outlines both preventive strategies and cleaning methods to mitigate buildup and maintain performance. I. Preventive Measures 1.
