High Resolution Interface (HRI) is a universal sensor that is compatible with a wide range of meters, including:
- Single-jet
- Multi-jet
- Piston meters with dry-dial and semi-dry registers in glass-copper or plastic housing
The HRI can be retrofitted on all Sensus meters built since 2008 that are pre-equipped with an HRI modulator.
The HRI is available in two versions:
- The HRI-A pulse unit is a high resolution pulser which detects the flow direction.
- The HRI-B data unit is an electronic register with a data interface which supports both hard-wired M-Bus systems and battery-driven MiniBus devices such as mobile meter reading systems. The HRI-B can alternatively be used as a pulse type with configurable pulse output.
The HRI is more than an extension of a simple sensor; it has been expanded to provide a reliable data source for reading a conventional meter remotely. It fulfills today’s requirements for data interrogation and remote transmission.
Typical applications include:
- Load profiles via a fixed network using M-Bus or via radio, telephone or GSM modem
- Industrial application (e.g., dosing)
- Remote reading of flow rate and cumulative flow using a frequency converter
- Leakage detection when connected to a data logger
- Generation and transmission of flow profiles using a data logger and GSM modem. The design of the HRI allows the system to be installed in extreme conditions, such as flooded meter pits.
