Ultrasonic flow sensors span wide temperature range

The sensors for domestic and industrial utilities metering that can be specifically tailored for individual customers.

Manufactured from a wide variety of materials including stainless steel, ceramic, thermoplastic or composite polymer, the sensors are designed specifically for customers’ own flow tubes, including features such as injection moulded ceramic reflector blocks, which enhance flow characteristics.

Temperature stability is critical to heat meter manufacturers to ensure accurate measurement of domestic hot water consumption utilised in district heating. This crucial property ensures flexibility, consistency and dependability in applications operating from 50ºC to sub-zero climates.

As well as tolerance to extremes of temperature, the sensors are resistant to contamination from sediment and particles, ensuring uninterrupted and reliable operation. This is particularly valuable in the water metering market.

Ewan Campbell, Product Manager for Morgan, explained: “We are continuously improving our understanding of ultrasonic piezoceramic sensors and are able to produce flow sensors that provide a high level of accuracy, in the conditions which they operate. Consistency is key and our ability to maintain accuracy when manufacturing in large volumes is of particular benefit to utilities companies. Each individual unit is tested before sign-off to ensure uniformity and reliability, allowing utility companies to take highly accurate energy usage measurements across vast numbers of properties without needing to measure temperature first.”

“These improved temperature stability characteristics are part of our ongoing advanced product quality planning programme, which allows us to design solutions which exactly match the needs of our customers – from utilities to automotive, aerospace, medical, pharmaceutical and other industrial applications.”
