Title: Liquefied gas filling system
Inventor: OTANI TOSHIYUKI
IPC: F17C6/00
Filed: 2000-03-03
Abstract: PROBLEM TO BE SOLVED: To rapidly conduct a filling operation from a tank lorry to a storage tank without depending on environment temperature or a container shape. SOLUTION: A storage tank liquid temperature detecting/sending device 30 is installed in a storage tank 20, and transmits liquid temperature data measured by a temperature sensor 32 to a tank lorry 10 by a sending portion 31 thereof. The tank lorry 10 receives the liquid temperature data sent from the sending portion 31 by a receiving portion 11, and measures the liquid temperature of liquefied gas stored in a tank 11 by a temperature sensor 15. A control portion 12 controls the number of revolutions of a pump 14 by increasing the number of revolutions of an engine on the basis of these liquid temperature data of the storage tank and the tank. When the liquid temperature of the storage tank is higher than that of the tank lorry, the control portion 12 increases the number of revolutions of the tank lorry engine so as to increasing a filling rate.  Therefore, reduction in the filling speed depending on the liquid temperature is prevented to enable a rational filling operation.
