Compact SMS/GPRS Pressure & Flow Data Logger

Compact SMS GPRS Pressure & Flow Data Logger

Cello is a family of GSM data logging devices for water and gas applications. Tens of thousands of Cellos have been installed throughout the world and Cello has become an industry standard for remote GSM monitoring.

It is a fully integrated GSM/GPRS data logger, with optional external battery or power options to enable frequent data transmission and/or logging rates. The GSM network is used to transfer recorded data, meter readings and alarm messages to a host computer or to the Internet by GPRS. Housed in a rugged, IP68 enclosure, Cello has a custom designed aerial to maximise GSM signal in underground locations; this avoids the inconvenience and expense of above-ground kiosks.

Flow and Pressure Data Logger

Flow and Pressure Data Logger

The Metrolog range of data loggers has been developed to provide low cost solutions for the monitoring of pressures and flows within water distribution networks.

  • 2 line light-activated backlit LCD
  • Internally powered and housed in a robust, fully waterproof enclosure (IP68)
  • Battery life > 5 years
  • Compatible with Technolog’s communication & configuration software for PCs, PDAs and hand held PCs
  • Metrolog P data loggers feature an integral pressure transducer

The Metrolog P : flow and pressure data logger utilising internal pressure transducer with a 3 way Mil-Spec flow input.
The Metrolog F : single channel flow data logger with no integral pressure sensor. The flow input cable is pre-wired to the unit.

Remote telemetry
