Flow meter

Electromagnetic flow meters are among the most widely used instruments in industrial process measurement—and also among those most prone to installation-related issues. Their output signal is extremely weak and easily affected by electromagnetic interference, so proper grounding and installation are crucial to achieving accurate and stable measurement. This guide explains why grounding is essential, how […]

Vortex flow meters are widely used across industrial automation due to their simple structure, wide turndown ratio, and strong adaptability. They are commonly deployed for measuring liquids, gases, and steam.However, in real operating environments, vortex meters may occasionally suffer from pulse loss — a condition where part of the vortex shedding signals generated by the

Vortex flow meters have long been appreciated for their wide applicability, no moving parts, and reasonable cost. They are commonly used for steam, compressed air, gases, and clean liquid measurement. However, in many industrial sites, vortex meters are often described as “unstable, inaccurate, or difficult to maintain.”In most cases, these problems do not come from

Background A client from Dubai required a high-accuracy flow monitoring system for concrete pumping operations. The system needed to measure both flow and pressure under demanding conditions — with a working pressure of up to 10 MPa and an abrasive medium containing cement slurry.Ordinary flowmeters often fail under such harsh environments due to excessive wear

In differential pressure flow measurement, the orifice plate, flow nozzle, and Venturi tube are the most commonly used primary elements. All three belong to the category of standard differential pressure devices, as defined in GB/T 2624, where their flow coefficients and discharge characteristics are well-established and can be used without individual calibration when designed and

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
