Flownetix 325 Consumer Water Meter

A 25mm (1") bore non-moving part consumer water meter.

Flownetix 325 Consumer Water Meter

The Flownetix® 300series™ is a unique range of consumer waters which have no moving parts and a full bore flow tube. They are ideal for use where mechanical meters traditionally fail due to air or grit in the water or high ambient and liquid temperature conditions. Non-measurement of air improves customer billing reliability.
