Water Distribution Monitoring & Control

Real-Time Pressure Monitoring Telemetry Transmitter System

Used in conjunction with a 4-20mA pressure transducer this 16-bit resolution transmitter can deliver real-time feedback from water distribution networks over distances of up to 7mile, 10k (subject to topology) to existing infrastructure without connection to the Internet or cellular networks.

Pressure Monitroing Transmitter

The Pressure Monitoring Transmitter can be order to operate on both Licensed and Licence Free Radio Spectrum in three operating bands and at power levels of 1W or 5W.

  • VHF 146-173MHz
  • UHF1 400-440MHz
  • UHF2 440-470MHz

The unit can be battery or powered from an external 12V dc power supply (2A). When battery operated the unit operates in a power save mode that permits the delivery of regular health messages, plus the automatic accelerations of reporting to minute rate in the event of low pressure permitting the signal to be used for real-time pressure management using PRV controllers, valves and/or pumps.
