Fuel is SentryFUEL's area of expertise with over 20,000 units sensing, monitoring and metering worldwide. Sentry Telemetry's class-leading sensors and gauges combine with battery powered radio, PSTN, GSM and satellite equipment - all with intrinsic ATEX safety approvals - to provide highly cost-effective solutions. 

Sentry Telemetry was started in 1997 to develop a low cost tank monitoring solution for the British Gas LPG division. Today, if you call into one of the thousands of auto-gas stations in France then it’s likely our equipment will be monitoring the tanks.

Products monitored include:
  • Oil
  • Diesel
  • LPG
  • Waste oils
  • Petrol
  • Lubricants
Collected tank data can be used for fuel ordering, transport distribution and routing optimisation, automated billing and to provide stock control and prevention of illegal filling.

Our SentryDATAplan™ package has been developed with a global IT services provider to enable a combination of financed equipment, web hosting services and support maintenance package that can be wrapped up into a monthly ‘provision of service’ fee.
