LITRE METER HELPS FIVES GROUP KEEP THE HEAT ON
UK flowmeter specialist Litre Meter has built on its largest ever order of 58 Sierra gas flowmeters from Fives Stein Limited. It has supplied the Oxfordshire-based manufacturer with a number of new instruments based on the robust Max-TrakŪ IP65 180 model.
The Sierra flowmeters supplied by Litre Meter are used to monitor oxygen and combustion gas flows on industrial furnaces used in the production of glass and ceramics.
Alan Stephens of Fives Stein explained: ?The meters are used to ensure the correct oxygen to fuel ratio in two furnaces ? one fuelled by natural gas, the other by LPG.
?We chose the IP65 180 model meters because they are capable of accurate measurements at very low pressure. This means that we can use them where oxygen is supplied from an on-site VSA (vacuum swing) plant.?
VSA is a process whereby oxygen is separated from air at a low pressure and then, in this instance, used with combustion gases to power the furnaces.
Alan Stephens added: ?Not only is the Sierra flowmeter capable of operating at the low pressures associated with the VSA process, it is also very robust. We need a meter that can cope with industrial conditions including the hot environment associated with glass furnaces.
?Another deciding factor in the choice of these meters was the fact that Litre Meter was able to supply some customised software for the meters measuring LPG because the type of gas used is not standard.?
The Sierra Max-Trak 180 features a Dial-A-GasŪ multi-gas capability and 316 stainless steel construction. It includes four types of analogue and two types of digital communication making it a versatile meter. It has a wide variety of field adjustable parameters and can measure and control flow rates from 10 to 1000 standard litre per minute (SLPM).
The Max-Trak 180 has an accuracy of +/- 1 per cent of full scale and a repeatability of +/- 0.2 per cent full scale, which ensures a stable process even under changing conditions.
The Dial-A-Gas feature enables a selection from up to ten gases in one instrument, creating great flexibility and reducing spares inventories. A powerful valve design enables the Max-Trak 180 to operate at low differential pressures.
