• The Petrosonic tank gauging system from Autovend records fuel levels in bulk storage tanks, meaning that daily fuel movements can be reconciled against pump totaliser readings for comparison of actual and notional tank stocks. It is a successor to the outdated and notoriously inaccurate dipsticks, says the company.
The Petrosonic system is based on an electronic probe which can be inserted in any rectangular or cylindrical tank. One sensor, attached to the probe, floats on the surface of the fuel, while another sensor, near the tip of the probe is designed to float on the surface of water which is commonly found at the bottom of fuel tanks. This way, accurate measurements are transmitted up the probe which is connected to a control cabinet indoors.
Not only is ullage (unfilled tank capacity) accurately determined but water levels in tanks can be measured to the nearest two or three millimetres or tenth of an inch. Actual fuel volumes recorded by the system are temperature corrected to 0.1% accuracy. Accurate tank temperatures can also be recorded indepen dently. Turbo
