What Are the Requirements for a Magnetic Flow Meter? Key Installation Considerations Key points

图片
Magnetic flow meters (magmeters) are widely used for measuring conductive liquids in industries like water treatment, chemical processing, and food production. However, their accuracy and longevity depend heavily on meeting specific requirements and proper installation. Here ’ s what you need to know:    Key Requirements for Magnetic Flow Meters  1. Fluid Conductivity      - Minimum Conductivity: The liquid must have a conductivity of ≥ 1 µS/cm (varies by model). Pure water or non-conductive fluids (e.g., oils) are unsuitable.     2. Full Pipe Flow      - Ensure the pipe is 100% full during operation. Air bubbles or partially filled pipes cause measurement errors.     3. Pipe Material      - Use non-magnetic pipes (e.g., PVC, stainless steel, or lined pipes). Magnetic materials (e.g., carbon steel) disrupt the meter ’ s magnetic field.     4. Grounding      - ...

What Is a Clamp-On Ultrasonic Flow Meter? A Complete Guide

图片
If you work with industrial piping systems, HVAC/R, or water treatment processes, you ’ ve likely heard about clamp-on ultrasonic flow meters. But what exactly are they, and how do they revolutionize flow measurement? In this article, we ’ ll break down their functionality, benefits, and ideal use cases to help you understand why this technology is a game-changer for non-invasive monitoring.    What Is a Clamp-On Ultrasonic Flow Meter?   A clamp-on ultrasonic flow meter is a portable, non-invasive device designed to measure the flow rate of liquids within pipes without cutting, drilling, or disrupting the system. Unlike traditional inline flow meters, it uses externally mounted sensors that clamp onto the pipe ’ s exterior. These sensors emit ultrasonic waves through the pipe wall to calculate flow velocity and volume based on the time it takes for signals to travel between transducers.     This method eliminates the need for pipe modifications, making it id...
