SANCHUAN industrial water meters—tough Woltman and high-performance ultrasonic—excel in demanding environments with R250 accuracy, corrosion-resistant coatings, and IP-rated durability. Designed for heavy-duty sites, they ensure reliable long-term operation under high flow and pressure.
Industrial environments present high flows, turbulent pipes, and large-diameter lines, often lacking ideal straight pipe runs. Harsh conditions—vibrations, temperature fluctuations, solids, and air entrainment—can impair meter accuracy. Measuring reliably over wide flow ranges, while minimizing downtime and calibration needs, remains challenging.
SANCHUAN’s industrial meters—Woltman and ultrasonic—offer:
Narrow accuracy to R250, even at varying flows
Robust, corrosion-resistant housings, IP ratings, tamper resistance.
Advanced connectivity (NB IoT/LoRaWAN), multi-sensor integration (pressure, temperature) for burst detection
With 88+ patents and in-house R&D facility, SANCHUAN offers solutions—like cast-iron Woltman water meter or ultrasonic DN100+ for wastewater. They deliver firmware customization, AMI integration, field calibration, and long-term support for industrial projects.
Flow range & pipe size: Measuring flow range from 156.25L/h to 2000m³/h.
Accuracy: R160/200/250 optional.
Environment: ensure materials and IP rating fit corrosive or high-temp settings.
Network needs: select NB-IoT/Pulse/RS485 models with remote reading, alarms, and valve control.
Certifications: verify compliance with local trade standards and calibration options.
SANCHUAN’s industrial meters—like the HP5D Woltman and ultrasonic models—feature R200/250 accuracy, epoxy-coated cast-iron bodies, low-pressure drop, and long lifespan. They're built to endure harsh industrial environments with sediment and high flows.
Woltman meters use impellers to measure high flow in large pipelines, offering stable readings and easy retrofitting with remote pulse modules .
Ultrasonic meters detect flow via sound waves with no moving parts, measuring from very low flows and supporting multi-sensor data and NB IoT connectivity.
With over 88 patents and in-house R&D, SANCHUAN offers custom firmware, pulse modules, NB IoT integration, and installation accessories (strainers, pressure gauges). They also assist with calibration and technical site support.
High-flow large pipes (DN50+): Choose the HP5D Woltman for durability and low head loss.
Precision and IoT needs: Use ultrasonic DN40–DN300 with R250 accuracy and NB IoT.
Harsh environments: Ensure meters have corrosion-resistant coatings, IP protection, and optional sensors for diagnostics.
