Cello XO is a multi-purpose fully integrated GSM/SMS/GPRS data logger, with optional external antenna and high
capacity battery options. The addition of a second pressure channel is invaluable for monitoring Pressure Reducing
Valves (PRVs) and Pressure Sustaining Valves (PSVs).The GSM network is used to transfer recorded data, meter
readings and alarm messages to a host computer or to the Internet by GPRS. Utilising the key features of the Cello
family, including long battery life, efficient use of GSM/SMS/GPRS remote communications and high reliability, the
following key features are available:
