Bulk ultrasonic water meters: Applications and benefits in smart water

In water distribution networks, traditional bulk mechanical water meters used in large-diameter pipelines often cannot accurately record microflows during nighttime or low-demand periods, and suffer accelerated wear due to high pressure and flow. 

As measurement accuracy declines, non-revenue water (NRW) tends to increase, impacting water management and operational efficiency. Moreover, these meters lack automatic data collection and remote monitoring, preventing digital management of key nodes and constraining the development of smart water.

For modern water networks, LAISON has developed the ultrasonic smart bulk water meter for large pipeline applications. By leveraging ultrasonic measurement technology with no mechanical parts, it delivers stable, high‑accuracy performance over extended service life while significantly reducing maintenance requirements.

Key Features:

• Fully electronic, no moving parts, maintenance free, long lifespan;
• No air measurement, installation angle flexible;
• Wide dynamic range (R400) and low initial flow rate, every drop counts;
• IoT ready (GPRS Comm.) for remote data collection and online monitoring;
• Water leakage/illegal meter dismantle detection & alarm to reduce non-revenue water (NRW);
• External valve optional, which supports prepaid working mode;
• Large battery capsule and power saving mode to ensure long battery lifespan;
• Fully sealed electronic module to ensure IP68;
• Reserved firmware upgrade portal, either via OTA or Bluetooth;
• 10 years' monthly consumption data record can be stored and queried.

Applications:

• Municipal water supply & DMAs: Installed at key nodes, detecting low night-time flows to reduce NRW and support proactive leakage control;
• Domestic Bulk Metering: Serves as a master meter for residential complexes and high-rise buildings, capturing low-flow leaks and ensuring accurate totalisation for large-scale housing;
• Commercial & Industrial Users: Maintains high accuracy across variable demand, ensuring reliable operation and long-term performance;
• Agricultural Irrigation: IP68 and no moving parts provide stable, long-term performance for efficient irrigation.

The LAISON ultrasonic smart bulk water meter significantly improves measurement accuracy in large-diameter pipeline networks, enabling precise billing, reducing water losses, and enhancing operational efficiency. Its digital capabilities support data-driven management and decision-making, providing a solid foundation for smart water development.
