IC-UPL Ultra Pro-Lite Portable Ultrasonic Flowmeter

Metri Measurements made in britain

The ProLite+ comes in a small package that is easily pocketable and importantly, affordable, but with great performance. The system uses advanced digital signal processing, as all the best flow meters of this type do. The flow meter has great signal diagnostics, and we supply the flow meter with everything required to get fast and accurate flow rate measurements within a few minutes. Three sensor sizes cover the range from 12mm to over 2 metres. There is also a configurable 4 M Byte internal datalogger for flow surveys. As well as the meter and sensors we provide a transducer rail, 2 rechargeable Lithium-ion batteries, ultrasonic couplet gel, data and charge cables, temporary sprung loaded chain fixings and a 5 m tape, in a carry case. We want to support you as a customer to get a great ultrasonic flow meter experience and will do everything we can to support you and give you the correct advice. iCenta have considerable application and design experience having been selling and supporting ultrasonic flowmeters for decades now.
