The Sensus SR-II water meters feature:
  • Magnetic drive meters with air tight, sealed registers, eliminate dirt, moisture, and lens fogging
  • Easy to read odometer-type, high-resolution, nine-digit display
  • Accurate, positive displacement, water measurement
  • Reliable and virtually maintenance free for long-term value
  • Tamper-resistant locking system helps prevent removal of the register to keep users from acquiring free water
  • Designed for horizontal installations and water flow in one direction
  • Manual direct read meter - not compatible with AMR/AMI
  • Available in USG (US Gallons) or CU (Cubic Feet)
  • 5/8" (DN 15mm), 3/4" (DN 20mm) and 1" (DN 25mm) sizes
  • Low-lead bronze housing (main-case and measuring chamber) exceeds requirements of the 2014 Federal Safe Drinking Water Act
  • ANSI/NSF Standard 61 Annex G/F compliant
  • Complies with ANSI/AWWA Standard C710-latest revision

When water flows through the measuring chamber, it moves the piston to oscillate around a central hub. A rubber coated division plate keeps it in place. A magnet relays the pistons motion to another magnet located inside the sealed register gear train, converting the piston rotation movements to volume of water displayed on the face of the register. This precision measuring design provides superior sensitivity for measuring a wide range of flows in a variety of residential applications.

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)

picture of 510m smartpoint end point transceiver
The Sensus 510M FlexNet® SmartPoint® features:
  • Radio transceiver gives water utilities access to water meter information through a radio signal
  • Remotely sends input information from the water meter register to a walk-by or drive-by collection device carried by water utility worker
  • Allows water meters to interface with the FlexNet® communication network
  • TouchCoupler design enables connection to the water meter using existing AMR two-wire installations instead of installing a new three-wire system into a home, saving water utility installation costs
  • Collects data and waits for an activation signal from the Vehicle Gateway Base-station (drive-by) or Hand-Held Device (walk-by) to transmit readings, meter identification and any alarms
  • Can be used as a fixed base endpoint to interact with a Regional Network Interface (RNI) (requires a base station)
  • Instantly transmits top of the hour readings and other diagnostic information to water utilities when used as fixed base end-point
  • Allows water utilities to effectively detect leaks in a water system
  • Multiple registers can be connected to this single SmartPoint
  • Not for submersible or pit installations. Must be surface mounted on wall

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.
