VEGA and Crabbie’s Alcoholic Ginger Beer
16 March 2011
John Crabbie & Co began trading in the ancient port of Leith in 1801 and soon became famous for Crabbie’s Green Ginger Wine. The unique recipe uses only use the finest, fresh ingredients from around the world: ginger from the Far East, fragrant oriental cinnamon and cloves, wild cowslips from Eastern Europe and fresh lemon and orange zest. It wasn’t long before one of Scotland’s favourite drinks was being exported throughout the British empire. Inspired by this heritage, and drawing upon years of expertise, Crabbie’s Alcoholic Ginger Beer was launched. It has since proved extremely popular and has gained strong followings in both the take-home sector and in bars and pubs across the land. Crabbie’s development has been supported by Radio, TV and poster campaigns and by the brand’s sponsorship of major events. Over the Christmas and New Year period all the Crabbie’s products look set to sell well and it is expected that sales will continue to grow strongly in 2011.To meet the increased demand, there was a requirement to upgrade the existing facilities and augment production capacity at the manufacturing plant. So, earlier this year, 9 new storage tanks with a capacity of 54,000 litres each were installed. As part of that project, John Crabbie & Co also required an accurate and reliable contents measurement for each new vessel. The information needed to be shared with production planning to meet growing demand, as well as having a local display so that operators could readily see the level on each tank. John Crabbie & Co turned to VEGA, who then supplied the new VEGAPULS plics-plus radar with enhanced performance. These new devices look at product level echo in much higher definition with an accuracy of ±2mm. The units are installed on 3" ANSI flanges in the roof of each vessel and fitted with encapsulated antennae, complying with the manufacturer’s stringent hygiene requirements. The radars were calibrated with individual vessel strapping tables, using the integral linearization table program within each sensor. The gauged tank volume is calculated internally by the instrument and the result is transmitted digitally without the need for external software, calculation or controller.
The system was installed, commissioned and has been working successfully ever since - so it’s ‘Crabbie’s Alcoholic Ginger Beers’ all round!The VEGAPULS sensors supplied for the tank gauging are connected using HART multi-drop communications with a fixed current of 4mA, where each unit is connected in a ‘star’ layout back to one main 2-core screened cable, thus reducing cabling, trunking and conduit costs. The sensor data is carried back on the main signal cable to VEGASCAN unit, this handles the information and converts it using an internal server to standard Ethernet computer protocols. This enables the tank inventory to be shared via the company LAN (Local Area Network). VEGASCAN also has capability of transmitting level alarms via e-mail and SMS or publishing level data to its own website. It also allows connection for using PACTware FDT/DTM universal sensor commissioning and maintenance software via the LAN with communication down to individual sensor level. The local tank readout is achieved using the VEGADIS 61: a display unit that connects and is powered directly from the head of the transmitter. This unit can be mounted up to 50m away from the sensor and offer a 5 digit scalable back-lit display and programming point at the base of each vessel.
