iPERL® Electromagnetic Flow Measurement Smart Water Meters

example of a 3/4 inch threaded water meter
The iPERL water meters feature:
  • Electromagnetic flow measurement meters with air tight, hermetically sealed registers, eliminate dirt, moisture, and lens fogging
  • Large Easy to read LCD programmable nine-digit display
  • Provides continuous and enhanced accuracy ranges at both high and low water flows
  • Registers flow as low as 0.03 gallons per minute
  • Reliable and virtually maintenance free for long-term value
  • Tamperproof: The integrated construction of the iPERL water meter prevents removal of the register to obtain free water
  • Smart alarm system detects tampering, main line breakage, leaks, and magnetic interference to reduce water losses and protect against unauthorized uses
  • Can be installed horizontally, vertically, or even diagonally
  • Compatible with current Sensus AMR/AMI systems
  • Available in USG (US Gallons) or CU (Cubic Feet)

iPERL®(North America) smart water meters offer unparalleled, low-flow accuracy with high-flow durability. The iPERL intelligent water meters are constructed with zero lead in the flowtube. They are made of fiber reinforced polyamide composite material which is stronger then plastic since they are made with two or more materials to create a superior strength material. This construction makes for less head loss compared to traditional positive displacement (PD) meters. And the iPERL meters can measure a 20 percent lower flow rate. They are also built to withstand high flows while maintaining measurement accuracy, enabling the capture of 100 percent of water flow. The iPERL water meter is able to capture lower flows because magnetic field flipping eliminates offset errors, thereby enabling the measurement of very low flows that other magnetic meters cannot measure. The iPERL have no moving parts to wear out or degrade accuracy over time and have a 20-year life cycle and a 20-year battery life.

Sensus OMNI R2 Water Meters

The Sensus Omni R2 water meters have a magnetic drive with an electronic register containing no mechanical gearing. These incorporate an innovative "Floating Ball Technology". The ball is water balanced and floats between the bearings allowing the measuring element to operate with almost no friction or wear. This creates extended upper and lower flow ranges only capable with the Omni R2 meter. The register can be programmable for Gallons, Cubic Feet, Cubic Meters, Imperial Gallons, or Acre Feet and has a 10 year battery life. The Sensus Omni R2 are part of the Sensus smart-water network utility management solution to meet the evolving needs of water utilities offering remote system management options via their two-way communications architecture.
  • Exceeds AWWA Standard C701 and C702 class II
  • Approved by NSF/ANSI Standard 61, Annex F and G
  • Meets requirements of the 2014 Federal Safe Drinking Water Act
The Sensus Omni R2 meters are compatible with AMR/AMI  (requires an end point transmitter sold separately)

Frequently Asked Questions

Q. "Why would anyone want these meters in cubic foot increments instead of gallon measurements?"
A. Many are still in existence in cubic foot measurements and some water companies still use the cubic foot measurement instead of in gallons. We don't know why anyone would prefer it that way but, we do sell/offer them.

Q. "Can I not use a union and install them with regular couplings or maybe use a soldered female adapter?"
A. You must use water meter unions on the 5/8"-1" models (most other brands will fit as well) because the threads (as with most brands of water meters) are non-tapered and require a rubber or neoprene washer to seal the connection. The Omni R2 and the SR models require special meter flanges as those two models have flange ends.

Q. "Do I need unions to hook the SR II water meters to a garden hose?"
A. You need unions to convert the threads on the SR II meters to IPS, and use hose fitting adapters from pipe fittings to hose size.

Q. "If you have to use these water meters with unions, why do you even offer them separately?"
A. Because most water meter brands have the same sized unions, many people buy these great meters from us as replacements for other brands and don't need new unions. However, for any new installation, a set of unions would be needed.

Q. "Can juices, vinegar, salt water, etc be run through these water meters?"
A. These are great water meters but are only designed for cold, potable water. Running any other fluid through them is not recommended, would not produce an accurate reading and will void the warranty.

Q. "I am looking for a water meter that I can install outside but read inside my house. Do you offer such a water meter?"
A. We do not offer any remote read water meters. The only water meters that we offer are on this page.

Q. "If I remove a meter from service for testing or repair, can I put it back into the system?"
A. If a meter is physically removed from service and it does not comply with the local regulations or standards, a compliant product must be installed. These water meters comply with low flow standards for California sub-metering, as well as current low lead legislation, making them an ideal choice for replacing your non-compliant water meter.

Q. "What are NPSM threads?"
A. It is the abbreviation for National Standard Free-Fitting Straight Mechanical Pipe Threads (NPSM). They are straight threads used only for joining and can not be threaded directly to National Pipe Thread Taper (NPT) fittings or piping. A washer or gasket is needed to seal this type of threaded connection.
