Installation manual
Description
Sensus PulseRF-Mei is a radio transponder connected to a
HRI-Mei pulse unit for Sensus C&I water meters MeiStream,
MeiStream Plus, MeiTwin and WPV-MS.
Equipment
1. Radio transponder connected to a HRI-Mei
2. Wall holder
3. Semicircular cover
1 Mounting of the HRI-Mei
Release the round cover from the hinge and replace it with the
supplied semicircular cover.
1. Open the cover for the OD with light pressure against the
left side
2. Turn blue ring counterclockwise (approx. 10°), pulser
sockets are open
3. Remove aluminum foil from the bottom of the HRI-Mei
module
4. Insert the two hooks of the HRI-Mei diagonally from
above into the holes of the backfitting ring
5. Push HRI-Mei down until it lies on the backfitting ring
6. Turn blue ring clockwise against stop (approx. 10°),
pulser sockets are locked
7. Close cover for OD. If required the HRI-Mei can be
protected with a seal wire against removal.
Communication
The SensusRF radio protocol is supported by SensusREAD or
DIAVASO and SIRT and allows the configuration and reading
of the Sensus PulseRF-Mei.
Sensus PulseRF-Mei is also supported by the Fixed Radio
Network Software IRIS and IRISlite.

2 Configuration
The radio module can be configured using SensusRF radio
with SIRT and configuration software.
• Activation by radio or automatic by first 10 pulses
• Sensus PulseRF protocol is encrypted with a default
encryption key
For the SensusRF radio module choose a position which
affects the radio signal as little as possible. Metal, soil and
water (e.g. power supply line or a water pipe) have a negative
impact on the radio range. The effect of plastic is lower than
concrete or wood. Try to avoid a position close to these
materials. In pits the transponder must be mounted above the
water line and at a minimum distance of 200 mm to metal lid
covers. Transponders should not be closer to each other than
80 cm. Test the best position before final installation.
Radio range
The typical distance between transponder and read-out
device is 500m@868MHz (350m@433MHz) in line of sight.
Inappropriate installation places, obstacles in the radio line-of-
sight and other influences like electrical interference or metal
devices can reduce the radio range or even make radio reads
impossible. From buildings to outside a typical range is 100 to
200 metres, while in an extreme case the reading range in a
pit might be less than 20 metres.
Installation of the wall holder
The wall plate is surface mounted using two
screws. Leave sufficient slack cable and space
so that the transponder can be replaced in the
future. Do not install the transponder upside
down!
Fitting / Removing the transponder
To fit the transponder push the rectangular protrusions on the
back into the mating holes in the wall plate and push down. To
remove the transponder, do it vice versa.
