Description

Our HRI-Mei sensor reading device is a data interface for pulse output for industrial water meters. It provides a high-resolution pulse output with a flow direction signal. The data interface can be used for M-Bus applications.

Designed for industrial water meters like MeiStream and MeiTwin, the HRI-Mei can be retrofitted without breaking your meter’s metrological seal. It is also built to withstand harsh environments, like flooded pits.

You can use the HRI-Mei for:

  • Industrial monitor and control applications and SCADA systems
  • Flow rate indication using frequency converters like FM-1D/K or FM-2D/K
  • Local meter reading for billing applications
  • Meter remote reading and profiling via cable fixed networks with M-Bus, radio modem or GSM network
  • Data logging in conjunction with various data loggers (i.e., CDL)

Benefits to you

  • Is compatible with commercial and industrial water meters like MeiStream and MeiTwin
  • Clips onto an appropriate water meter without breaking the meter’s seal
  • Detects water flow direction
  • Supports other applications requiring reed switches or optical pulse outputs
  • Accommodates a second pulser (depending on the register)
