The RF communication Terminal Unit - RFTU is an unlicensed
RF radio communication link from a remote wireless unit. It can be used
to send a Water meter data to the Power Line Communication (PLC)
Automatic Meter Reading (AMR) Collectric™ system.
The RFTU enables monitoring of Water, heating or other remote
meter.
The RFTU prevents the cumbersome use of connection wiring to
those meters.
The RFTU prevents the need of long distance radio communication
requiring expansive infrastructure and hard-to-get allocated radio frequencies.
The RFTU is extremely small size and can be adopted to any existing
meters.
The RFTU is equipped with a extremely long life battery operating
it for more than 15 years.
Using Collectric™ system, a Portable Display Unit
allows the readings to be displayed inside customer's premises.

Water Reading
- The transmitted signals are received by any near-by
Collectric™ system LC100 minimeter measuring electricity
or any dedicated RF receiver
- The receiver introduces the data into the power
line using Power Line Communication (PLC) to be received by Collectric™
system concentrator which stores the data for later report.
- No additional wires are required for reading the
Water meters.
- No long distance radio communication infrastructure and licensing required.
