Flowmeters

Thermal Mass Flowmeter

For compressed air, flare gas, ventilation and stable gas measurement.

Thermal mass flowmeters measure gas mass flow directly and are often considered for compressed air, flare gas, ventilation and multi-component gas applications after gas composition and operating range are checked.

A few operating details are enough to start an application review.

Medium → Flow → P/T → Pipe → Purpose

Installation and project details can be added if available.

What information is useful for flowmeter selection?

Flowmeter selection usually starts with the medium, operating flow range, pressure, temperature, pipe size and measurement purpose. Additional properties such as conductivity, viscosity, gas composition or installation conditions can be reviewed where relevant.

01

What is flowing?

Medium type

02

Flow range

Only one flow value is needed to start. Meter sizing should consider the operating range, not pipe size alone.

Operating conditions

04

Pipe size

Final meter sizing may differ from the pipe size.
