Rototherm’s Tank-i has been developed for level measurement on the vehicle fuel tank and is a solution that allows fleet operators to monitor, manage and ultimately protect their fuel.
Principle of operation
A small, non-invasive ultrasonic sensor is bonded to the external base of the fuel tank. The system calculates the height of the liquid in the tank from the time taken for the signal to be transmitted and then received from the liquid surface. Signals from the transducer are fed into the processor and then output to a separate system. The package is supplied as a sensor/processor pair. The system can be configured to work in a low power mode which can be controlled from the telemetry system where required. When combined with a telemetry tracking system, the fleet manager can get an accurate and up to date indication of the vehicles’ fuel consumption and be warned of any excess consumption, due possibly to fuel theft.
Tank-i is ATEX (safety) approved for hazardous areas and easy to install with no downtime and no penetration of the tank vessel. It can be retrofitted to existing fleets and is unaffected by temperature fluctuations. With no moving parts there is no maintenance on the unit.
Currently, Tank-i has found application in refrigerant receivers; low pressure gas (LPG) tanks; distilled spirits vats; beer tanks and tankers; pure water tanks; liquid chlorine tanks; acid and solvents tanks. Tank-i is used by leading beverage, pharmaceutical and chemical companies around the world for accurate, reliable, simple and safe tank contents gauging.
