Description
The Sensus CompactRF provides a solution to integrate Sensus
mechanical water meters with dedicated modulator blade in a smart
metering network using wireless technology.
1. Delivery parts
Sensus CompactRF, Bayonet ring, Dial cover with cut out, 2 screws, 2
screw seals, 1 adhesive seal
2. Installation
Mounting the Sensus CompactRF on the meter it is essential to remove
all foils and clean the surface of the register. A screwdriver Torx (T8) or
Slot (3.5*0.6) is recommended for mounting. The torque should be max.
0.6 Nm. Sensus CompactRF should not get any external mechanical load.
2.1 Water meters with plastic register
Put the Sensus CompactRF on the meter, so that the two pins on top of the
register fit exactly into the holes at the bottom of the Sensus CompactRF.
Fit the two screws. (Fig.
1
and
2
). For tamper protection fit the plastic
seals on top of the screws (Fig.
2
). After that change the cover (Fig.
3
).
The bayonet ring and the adhesive seal are not used for this register type.
2.2 Water meters with glass-copper register
Mount the Sensus CompactRF with both the screws on the bayonet ring.
For tamper protection fit the plastic seals on the top of the screws (Fig.
4
). Remove the lid from the meter (Fig.
5
). Fit the bayonet ring with the
mounted Sensus CompactRF on the top of the meter register and turn it
until it drops into place (Fig.
6
). Push and turn the bayonet ring clockwise
until the lever clicks into place. If required fit the adhesive seal.
To remove the Sensus CompactRF lift the lever and rotate anticlockwise.
If the bayonet ring should be secured against removal with a fixing screw
then the bayonet ring has to be mounted first onto the meter and fixed with
the screw. After that mount the Sensus CompactRF on the bayonet ring as
above. After that change the cover lid (Fig.
7
).
3. Configuration
To make sure that the meter ID and the reading are synchronized it is
required to configure the Sensus CompactRF after mounting to the meter.
Required tools:
• SIRT
• DIAVASO Config App installed at a Smartphone or Tablet
• Encryption key (possibly when the encryption key is different from
default)
Radio range
The typical distance between transponder and read-out device is
500m@868MHz in line of sight. Poor 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.

3.1
After starting the DIAVASO
Config App make sure that the
SIRT is connected via Bluetooth.
Add (+) device and enter the
address printed at the Sensus
CompactRF
3.3
After successfully retrieving the
info from the module it is possible
to enter the Custom meter ID that
is lasered on the meter. In this
example the Custom meter ID is
70250919
3.2
The DIAVASO Config then
will try to communicate with the
Sensus CompactRF.
3.4
As a next mandatory step
the counter reading from the
mechanical roller counter (see
image above) has to be transferred
to the Sensus CompactRF. (In our
example it is 00000.301).
Please consider the decimal
separator.
After these steps confirm the
settings
3.5
When the configuration
has been successful the new
counter reading should appear
and in synchronization with the
roller counter at the meter
.
