HRI - pulse and data transmission module

The HRI is a versatile sensor that is compatible with many types of water meters, such as single and multi-jet, volumetric and capsule dry and wet meters.

The HRI module can be installed on all counters manufactured by Sensus, which are equipped with a special HRI modulator that provides contactless (inductive) transmission of roller revolutions to the module.

Application

HRI modules exist in two such versions:

The HRI-P PulseUnit pulse module is a high resolution pulse transmitter with flow direction detection. The price of impulses can be from 1 to 1000 liters / impulse (determined when ordering).
The HRI-B DataUnit is an electronic module with a digital interface that has all the features of the PulseUnit and can also be connected directly to an M-Bus network or devices with a MiniBus interface. The customer can change the impulse price using specialized software.
The HRI module is the ideal solution for automated, error-free readings and their transfer to heat meters, archivers, remote reading devices, etc.
