Flow meter

Many may have noticed that when the pipe diameter is equal to or slightly larger than the flow meter’s measuring pipe diameter, the flow readings remain stable, and the flow coefficient is normal. Even if secondary flow occurs, the impact on the instrument is minimal. However, when the situation reverses and the pipe diameter becomes […]

Electromagnetic flow meters are widely used in municipal water systems, industrial wastewater, chemical processing, food and beverage, metallurgy, and pharmaceutical industries. They offer stable measurement, no moving parts, and long service life. However, the key to ensuring accuracy and reliability lies not in the instrument model, but in selecting the correct lining, electrode material, and

What Types of Float Flowmeters Are There? Where Are They Applied? Float flowmeters are widely used in various flow measurement applications. According to statistics, about 15% of domestic flow measurements utilize float flowmeters. There are two types: glass and metal. Glass Float Flowmeter: Suitable for measuring small to medium and micro flow rates. It can

The installation of the pressure tapping for throttling devices may seem simple, but it directly affects the accuracy of the measurement. This is especially critical when measuring steam flow on vertical pipelines, where the correct positioning of the tapping is key. However, in many cases, pressure tapping systems designed for aesthetics sacrifice signal transmission accuracy,

In modern industries, vortex flowmeters are widely favored for their broad applicability, especially in measuring gases, liquids, and steam. However, selecting the right vortex flowmeter is a complex process, involving considerations like flow range, pipe diameter, measurement accuracy, and medium properties. This document systematically explains how to choose the appropriate vortex flowmeter, avoiding issues of

Introduction A factory experienced repeated sensor failures in their vortex steam flow meters, with the failure occurring after some time despite initial checks. Each time before use, they ensured that any condensate was removed, yet the issue persisted. Is the problem with the quality of the vortex flow meter, or was there an oversight during

Clamp-on ultrasonic flow meters are non-invasive flow measurement tools, where the correct installation distance plays a critical role in ensuring measurement accuracy. Based on industry practices and technical standards, the installation distance must meet three core requirements: pipe straight length, interference avoidance, and sensor spacing. These factors are essential for ensuring stable signal transmission. 1.

Introduction Flow meters used in trade settlements must be regularly calibrated to ensure accurate readings. While factory calibration ensures the accuracy of a flow meter, installation-related issues can still affect its performance once the meter is set up on-site. On-site calibration, using portable standard devices, is a more reliable method to guarantee accuracy in real-world

Mass flow meters play a crucial role in accurately measuring multi-phase fluid mass flow. Their key advantages—insensitivity to changes in temperature, pressure, and viscosity—make them indispensable in the petrochemical industry, spanning the entire production chain from crude oil extraction to the dispatch of finished products. These meters are especially well-suited for high-temperature, high-pressure, corrosive, and

In the field of industrial flow measurement, differential pressure flowmeters are widely used due to their simple structure and durability. Among them, the segmental orifice flowmeter, as a special throttling device, shows unique advantages when dealing with dirty media containing bubbles, solid particles, or easily crystallizable substances. This article delves into the working principle, advantages,
