1. General:
The WER2 is used a water meter register that includes a magnet accelerator countin, LCD displpay,
sensors e.g. tilt and RF modem which holds the RF communication between he RMR and the metering
devices. The interface with the PC is done through wireless 2.4GHz short range communication. The
WERE2 radio is high power 1W UHF radio covers the 430 to 470MHz RF band. The WER2 is power from 2
AA bateris which are connected in serial.
2. Radio Specification:
a. General
• Battery voltage Internal 3.4 v …….. battery.
• Operating temp. -30 C°+50 C°
• Weight ……. mg
• Housing material Metal, glass, PVC
• Mechanical dimension at paragraph 13
b. UHF
• Rx/Tx Frequency bands:
• UHF Freq range………………………430-470.275MHz
• Tx Pout……………………….….… 1W+/-10%
• Rx sensitivity……………………… -117 dB
• Selectivity………………………..… -40dBc
• Supply voltage……………………... 3.4v typical. Min/max = 3.0/3.6Vdc
• RF data rate ……….………….……. 2.4K / 4.8K / at 6.25 Sp.Channel channels.
• GUP data rate ………………………..9.6Kbps
• RF freq set by GUP.
• Tx current……………………………670 ma
• Rx current……………………………. 22 mA Peak Currentin.

3. LCD Display
The LCD (Lquid Crictal Disply) is special & customized FSTN/TN low power LCD. The LCD includes 11
numbers fo meter consumption, and severak icons which show the neter stsus aws it is shown in the
next picture.
4. Parameter setting
The parmater setting is available in wireless connection (2.4GHz short range). A special 2.4GHz
adaptor (KP propriety) should be used together with a special SW utility / application the
“GUP” (rans on windows). The WER2 is usally in sleep mode (lowest current consumption
mode). A magnet swift is required to wake up the CPU. Once the CPU wakes up then the CPU is
looking for 2.4GHz special prompt. After the GUP identifies the device ID and this ID was

accepted by the user then the RF radio link is established. The WER2 upload all the unit
parametrs (see next chepters). The user can changed and dowenlods the new parameters.
a. General Setting
The General Setting includes the power modes: Power On and Flight Mode. The Flight mode is for
transportation or storage for long periode of time. The Flight Mode keeps the unit in the lowest level of
current consumer. In Flight mode the LCD is off as well as other periphrial like radio, sensors.
b. Drvice Parameters:
Drvice Parameters includes the radio long range parmeter i.e. the Tx and Rx radio frequencies (currently
the Tx and Rx freq should be the same. The device ID e.g. 40000. The number of wards in burst
repeatitions – it incread the communication reliability..

c. Meter Setting
Meter Setting parametrs includes: The Meter Value - it is the current water consumption figure. The
meter Factor which is defined for each type of meter (there are 4 paramters for each flow rate). Ther
Factor is the pulse/liter parameters. The Type parameter defines on of many meters.
