Metal Tube Float Flowmeter


1. Overview

Metal tube float flowmeter, also known as the “metal tube rotameter”, is a measuring instrument commonly used in the industrial automation process management to measure the variable area flow. Being featured with characteristics of small size, wide application range, convenient usage, etc., it is designed for measuring the flows of liquids, gases and steam, especially applicable for measurement of low flow speed and small flow rate.
