Introducing: Hydrophone 2
Introducing: Hydrophone 2

HWM is delighted to announce the launch of our new hydrophone sensor.

Designed for use with our full range of correlators and leak noise loggers, Hydrophone 2 is an all-new high performance sensor that delivers unrivalled leak detection performance.  Hydrophone 2 is particularly effective in plastic pipes where leak noise is low frequency, as well as in situations where fittings are a distance apart, such as on transfer and rural mains.

Our all new-sensor contains upgraded amplification circuitry, delivering a huge improvement in sensitivity to low frequency noise on plastic and trunk mains.


“Hydrophone 2 has been designed to be flexible, with a range of adapters available to ensure easy connection to meter manifolds, hydrants and other suitable connections worldwide.

 “Field testing has produced impressive results, particularly in difficult larger diameter and non-metallic pipelines and we are excited to be able to bring this huge development to market.”

Mike Tennant, Director of Sales and Business Development, HWM


Hydrophone 2 also features a push-fit pressure monitoring connection for bleeding and the attachment of a pressure sensor.  This means that, when connected to our Multilog LX TM data logger, both leak noise and pressure (transients) can be monitored at the same point.

This dual-parameter, single fitting monitoring is particularly useful on both transfer and rural mains where limited fittings are available.


Hydrophone 2 is available now.  For more information, and to download the datasheet, please click here.
