Mass Flowmeter for Gas Service (MFT-B Series)/Insertion, in-line, and portable type

General

This model is a thermal mass flowmeter for measuring gases including air and nitrogen in a wide range. Insertion type, in-line type, and portable types are available. By utilizing the wide range applications, it is best suited for energy consumption management.

Features

• 

Wide flow range, high accuracy

• 

Can display and output the normal flowrate (0°C, 1 atm) directly requiring no compensation of temperature and pressure

• 

High durability thanks to the absence of moving parts

• 

Low pressure loss
