UK flowmeter specialist Litre Meter has introduced a range of industrial flowmeters from Swiss manufacturer Vogtlin Instruments
The instruments are currently used to measure the flow of liquids and gases in a wide range of industrial and process applications.
Litre Meter is now able to supply the full Vogtlin range of thermal mass and variable area flowmeters to UK customers.
For gas flow measurement applications, Vogtlin thermal mass flowmeters use heat to measure flow.
Heat is introduced to the flow stream and the instrument measures how much heat is dissipated using temperature sensors.
The Vogtlin Red-y series has an accuracy of +/- 1 per cent of full scale and models have a measurement range of between 100 norm millilitres per minute (mln/min) and 5,000 mln/min.
The compact series is battery powered and has an LCD display, manual valve and alarm function.
Variable area flowmeters are robust and customisable.
They offer a measuring accuracy of +/- 2 per cent to +/- 5 per cent, even in long-term operation up to a temperature of up to 100degC.
The pressure of a fluid moves an internal float inside a glass tube along a linear scale enabling the flow rate to be calculated.
