Whisky flows faster

Whisky handling at United Distillers’ spirit processing complex in Cambus, Scotland, is being managed using Fisher-Rosemount’s Micro Motion Elite meters to monitor flows for tanker off-loading, on-loading and spirit reduction processes.

One result is that United Distillers (UD) has been able to increase the speed of tanker loading/unloading by up to 50%. Also 10 Micro Motion meters at the site have now received Customs and Excise approval.

Spirit produced at distilleries throughout Scotland arrives by road and is stored in stainless steel tanks at Cambus, before being filled into traditional oak casks for maturation.

Conventionally, 3in positive displacement (PD) piston meters and 3in piping are used, limiting delivery rates to around 70m3/hr, whilst UD wanted to increase flows to 90m3/hr. Flow rates of 90m3/hr per hour were attainable with Micro Motion.

Today, 12 Micro Motion CMF300 Elite meters are installed at Cambus, each connected to rack-mounted Model 9739 transmitters located in the main control centre. Four CMF300s are used to meter road tanker on- and off-loading, where the time to unload the 27,000 litre vehicles has been reduced from one hour to around 35 minutes.

To gain Customs and Excise site approval, United Distillers Engineering had to show that the meters were capable of consistently measuring flows to the required accuracy.

This was done in a series of tests by passing known amounts of spirit through several Micro Motion meters connected in series. Tests showed that it was possible to measure flows to 0.1% accuracy or better, with 0.05% accuracy actually being achieved. Over 52,000,000 litres of spirit were measured by Micro Motion meters during the first year of operation.

The mass flow, density and temperature outputs of the meters can also be put to other uses – for example, density and temperature can be used to derive percentage alcohol, currently measured by sampling. So there is now also the potential to eliminate sampling delays.

Further, in addition to providing for much faster loading/unloading, the meters do not have any moving parts so maintenance is minimal. They can also be blown-through after batch completion, to remove all traces of previous product.
