What is an Insertion Type Ultrasonic Flow Meter: A Complete Guide

Installing flow meters in large pipes often leads to high costs and complex modifications, causing project delays and budget overruns.

An insertion type ultrasonic flow meter is a device that measures flow by inserting sensors directly into the pipe through a tap or valve, eliminating the need for pipe cutting or system shutdown.

Insertion Type Ultrasonic Flow Meter Overview

Let me share my experience with these versatile instruments to help you make informed decisions.

What is the Insertion Type of a Flowmeter?

Many users struggle to choose between traditional inline and insertion flowmeters for their applications.

Insertion flowmeters are instruments where the sensing element is mounted through a hole in the pipe wall, measuring flow at a specific point and calculating total flow based on pipe profile.
