Pulsar's Non-contacting Measurement and Control Suits Center Parcs

Published on Wednesday, July 17, 2019

Pulsar were invited to work with Center Parcs throughout the project at Woburn Forest, the UK's fifth Center Parcs, because of successful installations at other Center Parcs developments, including at Sherwood Forest in Nottinghamshire. Pulsar's non-contacting ultrasonic systems are proven in tens of thousands of applications world-wide, with a heavy emphasis on wastewater treatment applications that provide operators with a host of built-in specialist functions. The Woburn project included measurement on Ferric tanks for the dosing system, control of the site pump chamber, measurement in an ATEX Zone 1 area for sludge control and on a v-notch weir, measuring screened influent flow. 

A wall-mounted Pulsar Ultra 5 was installed in the site pump chamber control system, connected to a dB6 transducer positioned above the wastewater that measures the time it takes for an ultrasonic pulse to reflect from the surface and converts it to a distance. Clever Pulsar software allows the system to ignore competing echoes from other items in the well and the five on-board relays are available to control pumps and other equipment through a sophisticated set of pre-built software tools.

Pulsar's Ultra 3 system was teamed with a high frequency dBMACH3 transducer to measure the flow through a v-notch weir, accurately logging screened influent to the site. The Ferric tanks within the dosing system are also monitored by a Pulsar Ultra 3, while yet another Ultra 3 measure the content of the sludge holding tanks. Pulsar's transducers are instrinsically safe, so the Zone 1 ATEX requirement in this area was eaily met. Finally, Pulsar's compact, self contained IMP units have been deployed to measure level in the influent screening tank.
