Description
Features & Documents
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)
