Litre Meter helps Fives group keep heat on24 October 2011

Glass and ceramics manufacturing plant builder Fives Stein has bought 58 Sierra gas flowmeters from specialist Litre Meter, because of their high accuracy in low pressure conditions.

The Oxfordshire manufacturer went for instruments based on the Max-Trak IP65 180 model to monitor oxygen and combustion gas flows on its industrial furnaces.

"The meters are used to ensure the correct oxygen to fuel ratio in two furnaces – one fuelled by natural gas, the other by LPG," explains Alan Stephens of Fives Stein.

"We chose the IP65 180 model meters because they are capable of accurate measurements at very low pressure, which means we can use them where oxygen is supplied from an on-site VSA [vacuum swing] plant," he adds.

Stephens makes the point that these instruments are proven, in terms of handling industrial conditions, including the heat associated with glass furnaces. "Another deciding factor was the fact that Litre Meter was able to supply custom software for the meters measuring LPG, because the gas used is not standard."

The Sierra Max-Trak 180 includes a Dial-A-Gas multi-gas capability and uses 316 stainless steel. It also includes four analogue and two digital communication channels and has a variety of field adjustable parameters.
