Flow meter

1. Introduction Hydrochloric acid (HCl) is a highly corrosive medium commonly encountered in chemical processing, water treatment, and pharmaceutical manufacturing. Accurate and stable flow measurement of hydrochloric acid requires a carefully selected electromagnetic flow meter (magmeter) with appropriate wetted materials. This document provides guidelines for material selection and configuration when measuring HCl with electromagnetic flow […]

Flow measurement is the science of studying changes in quantities, and the principle of mass interconversion is fundamental to the development and interconnection of all things. As such, the objects of flow measurement are no longer limited to liquid in pipelines in the traditional sense.  Any process that involves monitoring quantity changes requires flow measurement.

Accurate steam flow measurement isn’t just about velocity—it’s about mass flow, which depends on temperature and pressure. Traditional vortex flow meters measure volumetric flow, which is often insufficient for precise steam control. That’s where temperature-compensated vortex flow meters come in. In this article, we explore how integrated temperature compensation improves accuracy, what to look for

Measuring gas flow in industrial processes is crucial for safety, efficiency, and cost control. Two of the most common technologies are vortex flow meters and thermal mass flow meters. Both have unique strengths, but they operate on very different principles and are suitable for different conditions. This article compares these two technologies in terms of

Vortex flow meters are widely adopted across multiple industries due to their rugged design, ability to handle steam and gas, and low maintenance needs. Unlike many other flow meter types, vortex meters can operate effectively under high temperature, high pressure, and challenging flow conditions, making them a popular choice for utility measurement and process control.

When it comes to flow measurement in industrial systems, two widely used technologies are vortex flow meters and differential pressure (DP) flow meters. Both have proven reliable across industries, especially for steam, gas, and liquid applications. However, they differ significantly in principle, performance, installation requirements, and cost. This article compares vortex vs. differential pressure flow

When selecting a vortex flow meter, choosing the right output signal is as important as choosing the right size or material. Output signals determine how the flow data is transmitted, how easily it integrates into control systems, and what diagnostics or advanced functions are possible. This article compares the most common output types used in

In fluid mechanics, the relationships between pipe diameter, flow rate, flow velocity, and pressure are interconnected through various principles and equations. These relationships are crucial in designing pipelines for various applications, such as water distribution, oil and gas transport, and HVAC systems. Understanding how changes in one parameter affect the others is essential for optimizing

Vortex flow meters are trusted for steam flow measurement due to their robustness, high-temperature tolerance, and low maintenance. But like any instrument, they can face problems in real-world applications. This guide walks you through typical problems, their causes, and practical solutions, especially in steam service. 🛠️ Issue 1: No Flow Signal or Constant Zero Output

Differential pressure (DP) flow meters occasionally show no flow indication despite normal system operation. This article analyzes two real-world case studies and summarizes practical troubleshooting steps for diagnosing such issues. 📘 Case Study 1: No Indication in Ortho-Xylene Feeding Line Background:After restarting a benzene workshop post-maintenance, the DP flowmeter for ortho-xylene feeding consistently showed no
