- Solid-state, no moving parts: Prevents errors from sand, particles, and pressure fluctuations; long, maintenance-free life.
- Battery-powered: Internal battery—no external wiring needed.
- Durable & tamper-protected: Sealed, weatherproof, UV-resistant housing with a secure, non-removable register.
- High accuracy: ±1.5% sustained accuracy; ±3% at low flows.
- Easy-to-read display: 9-digit LCD showing consumption, flow rate, reverse flow, and alarms.

U500w Ultrasonic Flowmeter
The U500w Ultrasonic meter uses solid-state technology in 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.
- Building & property submetering: Compact, sealed design ideal for unit-level water measurement.
- Potable & non-potable use: Suitable for drinking water, reclaimed water, and challenging water conditions.
- Handles particles: Stays accurate even with small suspended particles.
- Sustained accuracy: Solid-state design avoids errors from sand, particles, and pressure fluctuations.
- Low-flow accuracy: Enhanced performance at low flow rates to reduce unaccounted-for water.
- High reliability: No moving parts for long-term durability and consistent performance.
- Technology: Ultrasonic transit-time (solid-state)
- Accuracy: ±1.5% in normal flow range; ±3% at extended low flows
