Digital Vertical Metal Tube Rotameter – Overview

This Rotameter is a variable area flow measuring instrument. The 16-bit microprocessor and high-quality components in the instrument ensure excellent performance of the flowmeter in various kinds of applications. The 304/316 stainless steel structure can be used to measure the flow of liquid, gas, and steam. It is especially suitable for measurement of low flow rate, microflow range, high temperature, high pressure, corrosive, conductive or non-conductive mediums. Applications include petrochemicals, chemicals, food and bev, water treatment and other industries.
