HWM Series IoT Large Diameter Horizontal Woltman Water Meter

Product Overview

The HWM Series IoT Large Diameter Horizontal Woltman Water Meter utilizes an advanced microprocessor to measure and record the volume of potable water flowing through water supply pipelines. Through NB-IoT/4G communication, the meter uploads data to the water management platform, enabling remote meter reading and billing management. The product can also integrate valve control functions. The valve-controlled version not only ensures accurate flow measurement but also enables remote water supply control, making it highly suitable for prepaid water management applications.

Product Features & Advantages

1. Stable & Reliable Communication: Based on carrier-grade communication networks, ensuring secure, stable, and reliable data transmission. Features deep signal coverage, low power consumption, and bidirectional communication with the software platform.
2. Innovative Structural Design: The electronic direct-reading section operates without mechanical contact with the internal counting mechanism, ensuring the original metering sensitivity remains unaffected.
3. Secure Data Transmission: Pure digital encrypted signal transmission guarantees safe and accurate data communication.
4. Ultra-Low Power Consumption: Equipped with high-density lithium-thionyl chloride batteries combined with voltage stabilization capacitor technology, providing a service life exceeding 6 years.
5. Flexible Data Reporting: Supports scheduled periodic meter reading, active wake-up, and real-time water consumption reporting. Threshold alarm settings allow immediate reporting when limits are exceeded.
6. Magnetic Drive Transmission Structure: The measuring mechanism adopts a magnetic coupling transmission structure with anti-magnetic interference capability. The measuring unit can be removed for maintenance or replacement without dismantling the entire meter, ensuring convenient servicing.
7. Remote Valve Control Function: Integrated control valve supports both local and remote valve opening/closing operations. Functions include prepaid management, remote water shut-off, and water supply restoration. For example, the valve can automatically close when overdue payments occur.
8. Comprehensive Intelligent Functions: Certain models support self-diagnostic capabilities, real-time monitoring of meter conditions (sensor faults, abnormal valve status, etc.), alarm notifications, data storage, and historical record inquiries.
