Flow meter

Selecting the appropriate protection rating for electromagnetic flow meters is crucial for ensuring their longevity and reliable performance, especially when used in harsh environmental conditions. The protection rating indicates the degree of protection provided by the device’s housing against solid objects and water ingress. In this article, we will explore the three common protection ratings […]

Magnetic flow meters, commonly used for measuring the flow of conductive liquids, rely on precise and uninterrupted signal transmission. While durable and accurate, these devices are sensitive to external factors that might interfere with their operation. One such factor is the use of graphite-based materials in sealing connections, specifically graphite gaskets and lubricants. This article

The U.S. Department of Energy’s investigation into compressed air systems found: Compressed air systems account for 10% of total electricity consumption in manufacturing. 70% of U.S. manufacturing plants have compressed air systems. 50% of these plants have the opportunity to save significant energy at low project costs. In manufacturing plants, awareness of compressed air efficiency

Introduction In the flow meter industry, zero drift—also known as zero offset—is the deviation of the flow meter’s output signal from the ideal value under zero flow conditions. Addressing this phenomenon is critical to maintaining accuracy and reliability in various applications. This article explores the causes, impacts, and mitigation strategies for zero drift, complemented by

1. Introduction The installation position of a mass flow meter is a critical factor influencing its accuracy and long-term performance. In most scenarios, it is generally not recommended to install a mass flow meter close to a pump. However, in constrained environments, this might be unavoidable. This article explores the installation requirements, potential challenges of

The corner-tap pressure measurement is a commonly used method in flow measurement systems employing orifice plates as primary flow elements. This method is highly effective for measuring differential pressure, which is then used to calculate the flow rate of a fluid (gas, liquid, or steam) in a pipeline. What Is the Corner-Tap Method? In the

When installing flow meters and control valves, the sequence of installation is a critical factor to ensure accurate measurements, protect equipment, and maintain system efficiency. This article explores the best practices for the installation sequence, the reasoning behind these practices, and special considerations for different flow meter types and industrial applications. 1. General Recommendation: Install

There are two forms of voltage and current changes when they are transmitted through wires, which we call “common mode” and “differential mode”. The power line of the equipment, the communication line of the telephone, and the communication line that exchanges with other equipment or peripherals have at least two wires. These two wires are

In industrial settings, differential pressure flow meters are essential for accurate measurement and process control. However, cases of no indication often arise, even when other equipment seems to be functioning normally. This article will analyze two case studies to uncover common issues and solutions, followed by a comprehensive guide to troubleshooting and maintenance. Case Study

The grounding of instrumentation system is divided into protective grounding and working grounding. I. Protective grounding Methods of protective grounding: The field instrument bridge and threading pipe should be connected to the grounded metal components with grounding wires every 30m. It should be pointed out in particular that the field grounding of instruments and meters
