Sensus iPERL® (International) Water Meter

Overview Industries & Applications Documentation & Tools

High Performance Static Water Meter with Patented Magnetic Field Technology

iPERL® (International) are next-generation, high-performance, solid-state smart water meters with integrated bi-directional communications capability. iPERL meters use a unique technology that provides unrivalled, sustained accuracy over their expected 15-year operational life.

Product Features
  • High measurement accuracy offering R800 metrology through all meter sizes (DN15 to DN40)
  • Up to 15-year expected operational life depending on communication frequency
  • High sampling rate with low battery consumption
  • Integrated bi-directional communication for AMR and AMI
  • Two low-power, public-spectrum radio systems
  • OMS certified
  • Data logger with up to 2880 parameters
  • Alarm functions
  • Tamperproof and fraud resistant
  • No moving parts
  • Zero-lead construction

With a low-flow measurement of 1 litre per hour, iPERL helps utilities to reduce non-revenue water. They can be programmed to provide highly granular data at 15-minute intervals, which improves accuracy in identifying customer-side leaks. The wealth of data also helps water utilities to manage distribution networks more efficiently, to conserve water, to provide accurate billing to customers and to inform them about leaks, fraud or unusual usage patterns.
