Abstract: PURPOSE:To measure a flow rate at a fast response speed with high precision irrelevantly to temperature by providing a flow rate measuring pipe with an electric heater and plural temperature-dependent resistances, and processing signals from those resistances and performing temperature compensation for the flow rate. CONSTITUTION:A tank 11 sends LPG, etc., to a pressure reduction chamber 121 and the LPG is sent to a flow rate measuring pipe 15 after dust is removed by a filter 14. The electric heater 13 is provided in the measuring pipe 15 and the 1st temperature- dependent resistance 41, the 2nd temperature-dependent resistance 42, and the 3rd temperature-dependent resistance 43 are provided its downstream, upstream, and further upstream sides respectively. Then, signals of the electric heater 3 and the 1st and the 2nd temperature-dependent resistances 41 and 42 are inputted to an arithmetic part 5 and linearized to measure the flow rate. Further, the 3rd temperature-dependent resistance 43 outputs the temperature compensation signal of measured gas and the 4th temperature-dependent resistance 44 outputs the temperature compensation signal of the support plate for the heater 3 to correct the flow rate. Thus, the temperature compensation for the measured gas is performed, so the fluid flow rate is measured accurately at a fast response speed with tolerance to contamination without reference to the gas temperature.

Filed: 1996-07-24
Abstract: PROBLEM TO BE SOLVED: To enhance identification of an upper end plug by conically tapering the transition part from a shank part to a barrel part and setting a different taper angle at the transition part for each end plug where the shank part has a different outside diameter. SOLUTION: A barrel part 10 is formed below a shank part 9 while enlarging coaxially by a required amount. The difference of outside diameter is small between the shank part 9 of an upper end plug 5a shown by (A) and the shank part 9 of an upper end plug 5b shown by (B) and visual confirmation thereof is difficult. The barrel part 10 has an identical outside diameter at the upper and end plugs 5a, 5b.
