Thermal mass from Bell Flow Systems

Bell Flow Systems offers a range of thermal mass flow meters designed for measurement of compressed air and Nitrogen. The TGF200 series are a smaller bore inline range starting at DN8 up to DN50 in size and the TGF450 and TGF600 series are supplied as flanged or insertion style units designed for pipes form DN25 to DN500. All these models have digital and analogue 4-20mA outputs with optional communication outputs such as Modbus RS485 and HART. Bluetooth is available with complimentary mobile phone app allowing the user to check and set meter parameters. It is also ideal for when the operator needs to view readings in hard to reach locations and provides efficient viewing when multiple meters are installed.

The TGF200 has four flow ranges with a 100:1 turndown ratio for each of the eight sizes, designed to suit the requirements of a variety of applications. This rugged unit is ideal for various industrial applications in factories, workshops and garages as it can be constructed from aluminium or stainless steel. With a fast response time of 160ms, this flow meter has a high accuracy level of +/-0.3% F.S and the meter can handle temperatures up to 100degc

The TGF450 and TGF600 flanged and insertion models are claimed to be ideal where the supply cannot be turned off or delayed in terms of installation and maintenance. These can be installed and removed via hot-tap connection if required, reducing costs and production delays. These models feature simple operator programming and it is also possible to adjust the flow calculation. These both have a two-line LCD display which can show both the rate of flow and total volume. The display can show volumetric and mass flow in kg or ton with the addition of programming options for alternative gas densities.
