WSF Metal Tube Float Flowmeter
Introduction
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.
Over the years, with its excellent property and reliability as well as preferable cost performance, the metal tube float flowmeter has been applied widely in a variety of industries, such as the petrochemical engineering, iron and steel, electric power, metallurgy, light industry, food, pharmacy, water treatment, etc.
Features
◆Designed for measurement of small caliber and low-speed medium
◆With reliable performance, few maintenance and long service life
◆Low requirement for the straight tube section
◆Widely measure ratio: 10:1
◆Dual-line display, instantaneous/ cumulative flow rates displayed at the field
◆With a keyboard on the indictor for convenient operation and setting
◆All in metal construction, designed for measuring corrosive medium of high temperature,
high pressure and strong
◆Non-contact magnetic coupling transmission
◆Applicable for inflammable and explosive occasion
◆Optional charging modes: DC power supply or battery power
◆With the functions of data recovery, data backup and power failure protection
◆Multiple parameters calibrating function
