Not every gas flow meter suits every gas application. Compressed air, LPG, natural gas and other gaseous products  each behave differently under pressure and temperature changes, and the right meter choice usually comes down to which specific gas you’re measuring and what you need from the reading.

Kobold BGN Flow meter above is suitable for flow measurement of liquid or gaseous products in pipes.

For measurement, monitoring, adjustment and control of liquid and gaseous products the Kobold BGN  all metal Variable Area Flow Meter is a great choice. The meters design makes it ideal; for processes under difficult and rough operating conditions. These devices are available with additional electrical equipment for process monitoring and control

Air Flow Meters
Series 1200 Variable Area Flowmeters suitable for Gaseous products

The Series 1200 Flowmeter is produced in three standard sizes.  Compact, Standard & Long series. Normally front of panel mounted, but can also be rear of panel mounted and supplied complete with bezel and panel mounting kit.  The 1200 Series Flowmeter will give an instantaneous flow rate of virtually any process gas or liquid.

Frequently Asked Questions

What type of flow meter is best for compressed air?

The Kobold BNG all Metal Variable Area Flow Meter with display is commonly used for compressed air, since they display directly and can handle high pressure applications. For low pressure applications the glass tube VA meters as shown above perform exceptionally well with accurate results

Can the same gas flow meter be used for LPG and natural gas?

Some meter technologies can handle both with the correct configuration, but LPG and natural gas have different densities and compositions, so the meter needs to be specified and calibrated for the specific gas type rather than assumed to be interchangeable.

Why does gas flow measurement need temperature and pressure compensation?

Gas is compressible, so its volume changes significantly with pressure and temperature. Meters that measure volumetric flow rather than mass flow typically need compensation for these variables to report an accurate, consistent flow figure regardless of conditions.
