High Accuracy Mass Flow Monitor/Inexpensive City Gas Flow Measurement

General

This is a thermal mass flowmeter suited for consumption management of city gas in addition to air and nitrogen. From an energy saving point of view, it is best suited for consumption management of city gas in furnaces, boilers, air conditioning equipment and the like.

Features

• 

Wide flow range, high accuracy

• 

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

• 

High durability thanks to the absence of moving parts
