CRANSWICK COUNTRY FOODS LTD. PROVE LONGEVITY OF DETECTRONIC MONITORING

Posted: Wednesday 4th July 2018

An ultrasonic clamp-on flow meter installed by flood and pollution prevention specialists, Detectronic, at a food processing site over two decades ago has more than exceeded its lifecycle expectancy.

Built in 1992, the Detectronic Monitor 8 unit was later fitted in the pump house of Cranswick Country Foods Limited's processing site in Watton in Norfolk. The unit has provided highly effective trade effluent monitoring at the site ever since with the last known recalibration being recorded in 2010.

Explains Phil Childs, engineer at Cranswick Country Foods: "We process pigs at our site here in Watton and this particular plant incorporates a large effluent pit that collects waste from various points located around the factory. Once it is collected, the effluent is then pumped over a filter screen to remove any large particles; the filter screen only lets particles of about 1mm through.

"The filtered effluent then goes into a holding tank from where it is pumped to lagoons about 4 kilometres away. As the effluent leaves the pumps there is a section of 100mm pipe approximately 2.4m in length. It is on this straight line of pipe that the clamp-on Monitor 8 meter has been located for the last 25 years. After this point the pipe leaves the pump house and goes into the ground and that is the last we see of it."

Phill Tuxford, technical support manager for Detectronic explains: "We've recently developed and brought into production the ORAKEL System. ORAKEL is a brand new, water flow-measurement and analysis solution that includes an ultrasonic time-of-flight flow measurement option.

"Following some issues with the Monitor 8 at the Cranswick Country Foods plant, we installed the ORAKEL System and remote-reporting datalogger as part of our pre-launch product trials, scheduled to run over a four week period. Phil Childs was so impressed with ORAKEL's performance that the day the trial finished, he issued a purchase order for the installed system!"

Phil Childs adds: "The lagoon end splits into four separate lagoons that belong to a local farmer. He needs to know exactly what we are sending down the line at any given time and the Monitor 8 and now the ORAKEL System enables us to supply that information and data as and when required.

"To further support the future growth of the business, we have discussed the possibility of creating our own effluent treatment plant on the site. In order to successfully implement this we will need robust and reliable data which is exactly what Detectronic's ORAKEL System is providing us with."

Concludes Phill Tuxford: "The average lifecycle of a Monitor 8 is ten years, so we are delighted with the performance of the unit at Cranswick Country Foods. The new ORAKEL System that is now in place has a lot to live up to but is already proving its value and has recently undergone its one year service calibration. We will continue to work closely with Phil Childs to ensure that Cranswick Country Foods know exactly what is happening with the site's trade effluent at any given time and deliver total regulatory compliance."
