Flow Meters
Our Thermal gas mass flow meters are capable of a wide variety of applications from compressed air, natural gas, biogas, hydrogen, combustion air and flare gas.
They feature all welded, no moving parts, direct mass flow sensors, suitable for dirty, corrosive, low flow applications that conventional flow technologies struggle with. We have been supplying the FCI Thermal flow meters in the UK for over 30 years and have a huge installed base.
Thermal dispersion technology measures the temperature difference between an active (heated) RTD and a reference (un heated) RTD. This is greatest in a no-flow condition and decreases as flow increases, cooling the heated RTD. Changes in flow velocity and density directly affect the extent to which heat dissipates and, in turn, the magnitude of the temperature difference between the RTDs. The flow meter therefore measures mass flow directly, without the need for additional temperature and pressure corrections.
Nitrogen Blanketing / Solvent Recovery
Nitrogen blanketing & vapour recovery are two techniques used to prevent the accumulation of potentially flammable volatile vapours within storage vessels and their subsequent loss to atmosphere. Thermal mass flow meters can improve plant efficiency by optimising the amount of nitrogen used.

Biogas flow
Comply with the latest OFGEM RHI regulations for gas flow measurement to Waste Gas burners, Flares & CHP units. The ST series thermal mass flow meters have no moving parts and are ATEX certified. They are ideally suited to measuring the flow rate of dirty, saturated biogas at minimal operating pressures.

Flare Gas flow
The accurate measurement of flare gas is becoming increasing important to operators as they are often required to report total emissions and total mass of carbon released to atmosphere.

Combustion air flow
Balancing the combustion air and fuel gas flow into industrial boilers, fired heaters & burners is essential in order to maintain efficiency and operate safely. The ST series thermal mass flow meters are widely used for both applications.

Hydrogen mass flow
Thermal gasification is becoming increasingly common and can treat a wide variety of organic waste materials with minimal atmospheric emissions. The result is a mixture of hydrogen & carbon monoxide. The Hydrogen can then be used for electricity generation or fuel cells.
