ISO 4064-2014 Compliant — Slim 2-Inch Profile, IP68 Protection, NB-IoT Smart-City Ready

Ultrasonic Water Meters are the modern technological successor to mechanical positive-displacement and turbine water meters — combining transit-time ultrasonic measurement technology with battery-powered low-energy electronics, smart-city wireless connectivity, and IP68 industrial-grade environmental protection to deliver accurate, durable, low-maintenance water metering for municipal water utilities, agricultural irrigation operations, garden and landscape management, water resource monitoring, and industrial production worldwide. 

Unlike mechanical water meters with rotating turbines or oscillating pistons that wear, jam, foul, and require periodic replacement, ultrasonic water meters have no moving parts in the water stream — meaning no wear-and-replace cycles, no pressure drop, no mechanical-fouling failures, and dramatically lower total cost of ownership across multi-decade deployments. Combined with built-in NB-IoT wireless communication for remote meter reading, RS-485 and M-BUS protocols for SCADA integration, and independent battery power lasting more than 15 years in some platforms, modern ultrasonic water meters are the foundation of smart-water infrastructure worldwide.

The global driver behind ultrasonic water meter adoption is the rapid digitalization of water management. Smart city programs, smart agriculture initiatives, water-loss reduction strategies, district-metering-area (DMA) deployments, and regulatory water-billing modernization all demand metering technology that is accurate at all flow rates, reliable across multi-year unattended deployment, remotely readable through wireless networks, environmentally robust in buried and outdoor installations, and engineered to international standards (ISO 4064-2014). Traditional mechanical meters cannot deliver these capabilities; ultrasonic water meters meet every requirement simultaneously — making them the de-facto standard for new municipal water-distribution metering, smart-agriculture irrigation networks, motor-pumped well monitoring, and water resource management programs.

Qualitest offers a comprehensive Ultrasonic Water Meter portfolio engineered to match every installation environment, pipe size, and connectivity requirement. The 2 & 4 Channel Ultrasonic Water Meter is the highly integrated multi-channel platform — fully compliant with ISO 4064-2014, available in two-channel or four-channel configurations, delivering a high range ratio, ultra-low power consumption, stable and reliable operation, with each component protected to IP68 enabling use in diverse, challenging environments. It supports wired RS-485 and M-BUS communications with DC 8-24 V power supply, plus wireless NB-IoT connectivity via a built-in 8 Ah battery for independent power. 

The Sandwich-type Ultrasonic Water Meter is the novel slim-profile platform tailor-made for agricultural irrigation, garden management, and water resource monitoring — featuring just a 2-inch (50.8 mm) slim form factor that minimizes installation space requirements, IP68 protection across all components, a unique design that mitigates the impact of water quality and pressure loss in the line, ultra-low power consumption delivering battery life exceeding 15 years, RS-485 connectivity, NB-IoT wireless networking support, an independent probe structure for stability and reliability, ultrasonic measurement eliminating any wearing components, and direct compatibility with motor-pumped well control cabinets for automated irrigation systems.

Why Choose Qualitest for Your Ultrasonic Water Metering Needs

Qualitest is a globally recognized supplier of advanced flow-measurement, water-quality, and analytical instruments, serving customers worldwide with one of the most comprehensive Ultrasonic Water Meter portfolios available — engineered for the precision, durability, low-maintenance operation, and smart-connectivity demands of modern water-utility, agricultural-irrigation, and industrial-water operations.

Two-Platform Portfolio — One Trusted Source

From the highly integrated 2 & 4 Channel Ultrasonic Water Meter for ISO 4064-2014 multi-channel municipal and industrial metering, to the novel slim-profile Sandwich-type Ultrasonic Water Meter tailor-made for agricultural irrigation and motor-pumped well integration — Qualitest offers a coordinated portfolio matching every installation environment, pipe size, and connectivity requirement.

ISO 4064-2014 Standards Compliance

The 2 & 4 Channel Ultrasonic Water Meter is fully compliant with the ISO 4064-2014 international water-meter standard — ensuring every test result is universally accepted, audit-ready, and defensible in customer billing programs, regulatory submissions, and utility-network performance reporting worldwide.

IP68 Across All Components

Both Qualitest ultrasonic water meter platforms deliver IP68 protection across all components — complete ingress protection against dust and water immersion. This enables reliable operation in buried installations, submerged pits, outdoor agricultural fields, motor-pumped wellheads, and aggressive industrial environments where lesser-protected meters would fail catastrophically within months.

Ultra-Low Power & 15+ Year Battery Life

Every Qualitest ultrasonic water meter is engineered for ultra-low power consumption. The Sandwich-type platform delivers battery life exceeding 15 years — eliminating the recurring battery-replacement cost, technician truck-rolls, and meter-downtime that plague legacy battery-powered metering technologies.

Smart-City NB-IoT Connectivity Built In

Both Qualitest platforms support NB-IoT wireless networking modules — enabling seamless integration with smart-city water-management platforms, remote-meter-reading networks, AMI/AMR utility systems, and IoT-enabled smart-agriculture controllers. Combined with RS-485 and M-BUS wired protocols, the result is universal compatibility across legacy SCADA, modern IoT, and hybrid utility data architectures.

No Moving Parts — Minimal Maintenance

Both platforms use ultrasonic transit-time measurement with no moving parts in the water stream. The Sandwich-type independent probe structure further guarantees stability and reliability, while ultrasonic measurement eliminates the wearing components found in mechanical, turbine, and positive-displacement meters — dramatically reducing maintenance cost and extending service life across multi-decade deployments.

Measure Every Drop. Power Every Smart-Water Program.

In every modern water utility, every smart-city water-infrastructure rollout, every agricultural-irrigation modernization program, every motor-pumped well retrofit, and every commercial-and-industrial water sub-metering project worldwide, ultrasonic water meters are the technological foundation that enables real-time consumption monitoring, leak detection, water-loss reduction, regulatory billing accuracy, and the sustainable water management that 21st-century communities require. A failed mechanical meter means undetected leaks, lost revenue, unbillable consumption, and customer-billing disputes; an inaccurate manual reading means missed water-loss events and regulatory non-compliance. The water utilities, agricultural operators, smart-city integrators, and industrial water-management organizations that consistently deliver precise, audit-ready, smart-connected water-metering data are the ones equipped with ultrasonic water meters built for ISO 4064-2014 precision, IP68 durability, NB-IoT smart connectivity, and ultra-long-life battery operation — and the Qualitest Ultrasonic Water Meter portfolio gives you exactly that.

Whether you are deploying a smart-city water-distribution network, modernizing an agricultural-irrigation operation with motor-pumped well monitoring, rolling out district-metering-area programs across a municipal utility, supporting industrial water sub-metering for sustainability programs, or building water-rights accounting systems for regulatory agencies, Qualitest has the ultrasonic water meter engineered to meet your exact needs.
