摘要： PROBLEM TO BE SOLVED: To enable a worker to easily ascertain the condition of liquid injection when a liquid is injected into tanks, by providing an automatically changing-over means for display, which automatically changes over a display on a display unit of a liquid amount monitor so that information on an amount of the liquid in a tank specified by a tank specifying means is displayed. SOLUTION: An amount of oil in each oil storage tank is measured (S4) on the basis of a detection signal from an oil level detector. Then, whether an amount of oil in any one among the oil storage tanks has increased is determined (S5), and, in the case where the result of determination is NO, a step is returned to the preceding step (S4) of measuring an amount of oil, while, in the case of YES, an oil storage tank, in which an amount of oil has increased, among the oil storage tanks is specified (S6). Then, whether the number of tanks receiving oil injection is one is determined (S7), and, in the case of YES, a display screen of an oil amount monitor is automatically changed over (S8) so that information on an amount of oil in one tank receiving oil injection is displayed, while, in the case of NO, the display screen of the oil amount monitor is automatically changed over (S9) so that information on an amount of oil in each of two or more tanks receiving oil injection is simultaneously displayed.

摘要： PURPOSE:To calibrate the A/D-converted digital value of a temperature detection circuit to a proper temperature reading by registering each characteristic of a thermometer resistor. CONSTITUTION:The temperature signal composed of an A/D-converted digital value corresponding to the resistance value of a thermometer resistor 8 of a temperature measurement circuit 5A at the lower limit temperature is set and registered in a memory. Then the tempersture signal composed of an A/D- converted digital value corresponding to the resistance value of the thermometer resistor 8 at the upper limit value is set and registered in the memory. Then A/D-converted digital values are cabibrated to proper reading from the characteristic of the thermometer resistor 8 based on the digital values corresponding to the lower- and upper-limit temperatures registered in the memory.

摘要： PURPOSE:To prevent an accident that an incorrect sort of liquid is fed during liquid feed operation by a tank truck. CONSTITUTION:An oil sort judging device 12 is mounted on the midway of a liquid feed pipe 5 through which oil liquid flows when liquid oil is fed to a storage tank 43 provided in a gas station from a transportation tank 2 mounted on a tank truck 1. The oil sort judging device 12 detects the dielectric constant and density of the oil liquid flowing along the liquid feed pipe 5 and judges the oil sort based on the detected results. The result of judgement by the oil sort judging device 12 is indicated on a monitor 36 provided on the right side of the tank truck 1 to let an operator notice it. Therefore, the operator can confirm the oil sort before oil liquid is fed to the storage tank 43, and an accident such as oil mixing can be prevented.

摘要： PURPOSE: To release the internal air of an injection hose when oil is fed to an underground tank, and ensure the detecting operation of an oil kind sensor. CONSTITUTION: An opening and closing valve 34 is provided near the distant feed port of an underground tank, and an oil kind detecting sensor 21 formed of a dielectric sensor 22 and a specific gravity sensor 28 to detect the feed oil kind is provided on the opening end side of the distant feed port over the opening and closing valve 34. An air vent valve 35 is provided on the opening end side of the distant feed port over the opening and closing valve 34, and an air vent piping 42 bypassing the opening and closing valve 34 is provided on the outlet port of the air vent valve 35. Thus, when the injection hose of a tank lorry is connected to the distant feed port, the air filled in the injection hose is released on the underground tank side through an air passage, the oil from the tank lorry is fed into the distant feed port, and the oil detecting sensor 21 is filled with the oil to ensure the oil kind detection.
