Blue Tower Automatic Meter Reading (AMR) systems for water, gas and electric utilities, combine the advantages of open systems and fast data acquisition for the benefit of utilities. The Blue Tower radio frequency (RF) systems are designed with open systems philosophy in mind: compatibility with utilities' existing equipment means lower initial investment. A unique protocol allows for global reading; improved efficiency means reduced meter reading costs.

The 400 Series Transponder
The Blue Tower Meter Interface Unit.

The Transponder is an RF receiving and transmitting device that connects to the meter and sends data to the data collection device, the HandTrackIT®.

The Transponder listens continuously for a short code signal from the HandTrackIT® and responds with a meter reading.
All Transponders with matching utility code respond to this request. Collisions are avoided by sophisticated collision avoidance algorithms.

The Transponder can be fitted or retro-fitted in minutes to most meters. The list of compatible meters is growing continuously. The Transponder is suitable for internal and external installations. It reduces reading time in pits, vaults, basements and other 'hard to read' meter locations.

The Transponder is IP67 or IP68 waterproof rated, dependending on product type, and meets EN 300-220 and EN 300-683 European Standards. It does not require a licence for operation.
