The U500w Ultrasonic meter uses solid-state technology in a compact, totally encapsulated, weatherproof, and UV-resistant housing, suitable for building and property management submetering applications. Electronic metering provides information—such as rate of flow and reverse flow indication—and data not typically available through traditional, mechanical meters and registers. Electronic metering eliminates measurement errors due to sand, suspended particles and pressure fluctuations.

APPLICATIONS
Use the U500w meter for measuring potable cold water in building/property management and industrial applications. The meter is also ideal for non-potable, reclaimed irrigation water applications or less than optimum water conditions where small particles exist. The U500w meter complies with applicable portions of ANSI/AWWA Standard C700 and NSF/ANSI Standard 61, Annex G. There is currently no AWWA standard that specifically addresses ultrasonic meters for residential applications.

OPERATION AND PERFORMANCE
As water flows into the measuring tube, ultrasonic signals are sent consecutively in forward and reverse directions of flow. Velocity is then determined by measuring the time difference between the measurement in the forward and reverse directions. Total volume is calculated from the measured flow velocity using water temperature and pipe diameter. The LCD display shows total volume and alarm conditions and can toggle to display rate of flow

CONSTRUCTION
The U500w meters feature an engineered polymer, lead-free meter housing, an engineered polymer and stainless steel metering insert, a meter-control circuit board with associated wiring, LCD, and battery. Wetted elements are limited to the pressure vessel, polymer/stainless steel metering insert and the transducers. The electronic components are housed and fully potted within a molded, engineered polymer enclosure, which is permanently attached to the meter housing. The transducers extend through the polymer housing and are sealed by O-rings. The metering insert holds the stainless steel ultrasonic reflectors in the center of the flow area, enabling turbulence-free water flow through the tube and around the ultrasonic signal reflectors. The metering insert’s patented design virtually eliminates chemical buildup on the reflectors, ensuring long-term metering accuracy.

METER INSTALLATION
The meter is completely submersible and can be installed using horizontal or vertical piping, with flow in the up direction. The meter will not measure flow when an ”empty pipe” condition is experienced. An empty pipe is defined as a condition when the pipe is partially full.

  • Minimum extended low-flow rate lower than typical positive displacement meters.
  • Simplified one-piece electronic meter and register that are integral to the meter body and virtually maintenance free.
  • Sealed, non-removable, tamper-protected meter and register.
  • Easy-to-read, 9-digit LCD display presents consumption, rate of flow, reverse-flow indication, and alarms.
  • Battery powered—eliminates wiring.
  • Compatible with AquaCUE® Flow Measurement Manager.
