Swansea Deep Well

Summary
The reliability and versatility of the advanced echo processing technology in Pulsars non-contact ultrasonic range has been utilised at the Swansea Waste Water Treatment Works, in a 23m deep application where other manufacturers had failed to provide a reliable low level signal. In order to minimise problems, such as pump clogging, resulting from solids accumulations, a wet well cleaning cycle routine was designed into the pump cycle, requiring low level control below the pump heads. The Pulsar Ultra 3 and dB40 transducer now provide continuous and reliable low level measurement allowing the above routine to be included in the normal pump cycle. read more ...

Echo confidence for Severn Trent at Derby STW

Summary
Pulsar Process Measurement supplied non-contacting ultrasonic level measurement equipment into the main transfer pumping station at Severn Trent Derby STW, in an application where other manufacturers had failed to provide a reliable signal. The arrangement of the site and surrounding land makes an overflow unacceptable.The maintenance on float switches was an unpleasant chore for site staff, with heavy ragging of floats and false alarm signals produced. A non-contacting solution was imperative. The Pulsar Ultra 3 level controller coupled with dB15 transducer is now providing reliable measurement, so much so that with the exception of ultimate high level alarms, the float switches are being removed. read more ...
