Smart modules for remote meter readings

H11 – Water Meter

The Hydro Meter H11 is a wireless GSM module for remote meter reading (water meters, electricity meters, gas meters), i.e., smart metering. It provides operators with a continuous overview of current consumption at individual consumption points and allows them to monitor emergency situations in near real time.

  • Compatible with any pulse water meter
  • Backflow indication and indication of sensor disconnection from the water meter
  • Daily meter readings
  • Detection and logging of exceptional events
  • Data transmission intervals configurable: daily, weekly, monthly
  • GPRS with automatic carrier selection
  • Local NFC communication (phone, tablet)
  • Mechanically robust design, high IP67 protection rating, corrosion-resistant materials, self-diagnostic functions
  • Maintenance-free operation with no battery replacement required throughout the water meter’s service life

Description

The module can be used to monitor the water meter’s counter status and certain exceptional events, such as: backflow, excessive instantaneous flow, exceeding the moving sum of the volume of water passed through, exceeding the nighttime minimum, or detection of the sensor being disconnected from the water meter.
The current water meter reading is recorded daily. The frequency of data transmissions can be configured to occur daily, weekly, or monthly. Exceptional events are sent with priority—immediately upon detection.
The Hydro Meter H11 is designed for compact dimensions and long-term durability when operating in extremely humid environments. It meets the IP67 protection standard. The device body is made of chemically stable plastic, and the mount is made of stainless steel. The design ensures that the device can operate reliably and unattended for at least the duration of the water meter’s service life—i.e., 6 years.

Applications

  • Remote water meter readings in water supply networks (continuous monitoring of current water consumption at individual supply points or monitoring of emergency situations)
