<P>PROBLEM TO BE SOLVED: To obtain a turbine flowmeter with simple constitution for providing an LP gas supply machine whose installation space is made small. <P>SOLUTION: In the LP gas supply machine which supplies LP gas to a storage tank while measuring it by a predetermined amount, a turbine flowmeter A comprises a rotor 3 which rotates as a liquid passes and a housing 1 in which the rotor 3 is incorporated rotatably, and is provided with a flow rate detection part 11 which detects the rotation of a blade 4 of the rotor 3 in the housing 1 nearby a rotation locus circle of the blade 4; and a second bottomed attachment hole 23 having a thin-wall part 22 with an inner wall surface of a measuring chamber 2 is bored, and a temperature measuring instrument 21 capable of measuring the temperature of the liquid through the thin-wall part 22 is incorporated in the second bottomed attachment hole 23. Consequently, when the LP gas is charged in a vehicle, the supply machine itself can be made small and the installation space is reduced. Further, the temperature measuring instrument is never in direct contact with the liquid, and no turbulent flow is thereby generated. <P>COPYRIGHT: (C)2012,JPO&INPIT |
