Non-mechanical cold & hot water meter with exceptional R800 low flow registration capability. Water temperature range from +0.1° C to +70° C with conductivity as low as 25 µS/cm with a wide variety of applications from monitoring consumption of apartments and commercial revenue meters to rural water systems. OIML R49: R800 approval - 16 Bar.
Whether internet, telephony or electricity - intelligent network communications are all around us and offer almost unlimited possibilities. So why not apply the same principle to one of our most important resources - water.
Worldwide, water networks need to keep pace with the development of intelligent network communications to ensure they are up to date with demand-driven automation and load management that is standard in the smart grid.
Using a fixed AMI communications network (such as Sensus FlexNet™), iPERL can help identify potential issues, such as leakages in the network, enabling you to address them quickly. This saves your business time, money, improves targeting of field crews, and increases customer service levels.
Sensus iPERL offers unrivalled, sustained R800 measurement accuracy for all sizes from DN15 to DN40 over its expected 15 year operational life when used for clean potable water:
Unlike other solid state meters, iPERL uses remanent magnetic field technology which provides a linear measurement range even down to very low flow rates. The magnetic field acting on the water flowing through the flow channel generates an electrical voltage; this is proportional to the velocity of the water (principle of magnetic-inductive flow measurement).

iPERL delivers constant accuracy in a wide range of installation conditions and can be installed in any orientation without the need for linear pipe leads in or out. iPERL also has an automatic detection of the direction of flow, further enabling the choice of installation positions when operated in accordance with the framework conditions as set out in MID (European Directive 2014/32/EU) and European standard EN 14154:2005+A2:2011.
iPERL is equipped with either a standards compliant low power - 433 MHz integrated radio technology. The innovative communications provide for walk-by / drive-by collection, plus the ability to interrogate meters for more detailed data, including the log of up to 2880 data points and alarms.
Along with Sensus radio, iPERL also offers an OMS certified broadcast platform. This provides for connection to the Sensus FlexNet AMI system, allowing iPERLs to migrate from walkby / drive-by collection to a fixed network in the future without having to visit the meter.
Overlaying the metrological performance curve of iPERL and a representative ultrasonic solid state flowmeter (green), demonstrates this extreme benefit.
Based on its outstanding metrological performance, iPERL ensures that the water utility accounts for the water supplied to the consumer, thus representing a considerable reduction in Non-Revenue Water.
