Products Description
The pulse-output water meter is a residential ultrasonic water meter designed with cutting-edge technology. It integrates intelligent wireless communication and advanced data analysis capabilities, delivering exceptional metrological performance to effectively reduce non-revenue water (NRW) and enhance water utility benefits. Featuring an innovative structure, the product offers a service life of up to 12 years, significantly outperforming traditional mechanical water meters.
With no internal moving mechanical components, it maintains stable measurement accuracy throughout its entire lifecycle and requires zero maintenance. Furthermore, the use of high-strength, pressure-resistant engineering plastics combined with brass materials substantially improves the product's wear resistance and durability.

Main Features

1. Accurate coverage of flow rate (R400): Flexible adaptation of dynamic range ensures measurement accuracy throughout the entire flow rate range.
2. Pipeline compatibility optimization (U0/D0): Directly install without pipeline modification requirements, reducing deployment costs.
3. Micro flow sensitive monitoring (10L/h): Accurately capturing extremely small water usage to prevent measurement omissions.
4. Strong anti-interference ability: Impurities in water quality and external magnetic fields do not affect the accuracy of measurement results.
5.12 years of long-term operation: The lifespan far exceeds that of conventional equipment, reducing replacement and maintenance costs.
6. Omnidirectional installation flexibility: Vertical/horizontal pipelines can be installed and used immediately without the need for structural adjustments.
7. Pure water metering mode: actively eliminates air interference and outputs real water flow data.
8. IP68 full environmental protection: maintains stable performance even in extreme dust and humid environments.
