Flow meter

In many industrial applications, engineers often encounter a frustrating issue: 👉 The electromagnetic flowmeter shows “empty pipe alarm” — even when there is flow. This problem can lead to: Incorrect readings Process interruptions Unnecessary troubleshooting costs In this guide, we’ll explain the real causes, practical solutions, and how to avoid this issue in your project. […]

Choosing the right flowmeter is critical for process accuracy and cost control. Among all technologies, Coriolis mass flow meters are known as the most accurate solution.But are they always the best choice? 👉 In this article, we break down the real advantages, limitations, and application scenarios to help you make the right decision. 🧠 What

1. Introduction In modern industries such as fine chemicals and pharmaceuticals, precise solution preparation is critical. However, traditional measurement methods often face a common challenge: How can we accurately measure the solute content in a solution without complex analyzers? Coriolis mass flowmeters provide an efficient solution by enabling a shift: 👉 From fluid measurement →

In steam flow measurement, vortex flow meters are commonly used due to their reliability and simplicity. However, when temperature and pressure compensation is not properly implemented or installation points are wrongly selected, even small errors can lead to significant measurement inaccuracies. This article provides an in-depth overview of the underlying logic of temperature and pressure

Vortex flow meters are widely used for measuring steam, gas, and liquid flow in industrial applications due to their simple structure, good stability, and low maintenance requirements. However, during operation, users may occasionally encounter situations where the flow meter shows a minimum reading or no output signal at all. This problem can be caused by

Vortex flow meters are widely used for steam flow measurement because of their stable performance, simple structure, and low maintenance requirements. However, in many industrial applications, users may notice that the flow reading fluctuates significantly when measuring steam. In most cases, this phenomenon is not caused by instrument failure. Instead, it is usually related to

Electromagnetic flowmeters operate based on Faraday’s law of electromagnetic induction and are used exclusively for conductive liquids (conductivity ≥ 5 μS/cm). In the chemical industry, the core focus of selection revolves around medium compatibility, operating conditions, accuracy/signals, installation/explosion-proof requirements, and structural/functions. Below are practical selection rules specifically for chemical industry scenarios. 1. Prerequisites: Determining Medium

Orifice flow meters dominate the industrial steam flow measurement field due to their simple structure, high reliability, and wide applicability. However, the high temperature and phase-change characteristics of steam present significant challenges in the stable transmission of differential pressure signals. As a key component in the pressure pipe system, the proper setup of the condensate

The working principle of electromagnetic flow meters is based on Faraday’s Law of Induction: when a conductive fluid flows through a magnetic field, it cuts through the magnetic flux lines, generating an induced electromotive force (EMF). The magnitude of this EMF is proportional to the flow velocity, which is then used to calculate the flow

1. Core Principle (Kármán Vortex Street) When fluid flows past a non-streamlined vortex generator, alternating vortices are formed on either side, arranged in a regular pattern (Kármán Vortex Street). Vortex shedding frequency: f=St×vdf = St times frac{v}{d} StSt : Strouhal number (approximately 0.16–0.22, stable within Reynolds number 2×1032 times 10^3  to 7×1067 times 10^6 )
