Title:
DETECTOR OF SAMPLE FLUID AND METHOD AND APPARATUS FOR MEASURING AND ANALYZING SAMPLE FLUID USING THE SAME
Document Type and Number:
Japanese Patent JPH04158214
Kind Code:
A
Abstract:
PURPOSE:To enable the simultaneous measurement of the flow velocity and flow rate of a sample fluid by providing a through hole i each of a total pressure chamber, a static pressure chamber and a sample fluid collecting chamber and by providing mechanical-electric conversion elements between the chambers respectively. CONSTITUTION:The inside of a cylinder 2 constructing a main body is made up of a total pressure chamber 3 sectioned by a hermetically closing cap 8 and a first mechanical-electric convertion element 9, a static pressure chamber 4 sectioned by the element 9 and a second mechanical-electric conversion element 10 and a sample fluid collecting chamber 5 formed of a space from the element 10 to an open end of the cylinder 2. A total pressure hole 11, static pressure holes 12 and 13 and a sample fluid suction hole 14 pierce the respective lateral sides of the cylinder 2 of the total pressure chamber 3, the static pressure chamber 4 and the collecting chamber 5. A lead wire passing groove 29 provided on the lateral side of the cylinder 2 on the opposite side to the aforesaid holes embeds lead wires 16 and 17 of the element 9 and lead wires 18 and 19 of the element 10 and leads them out. According to this constitution, the elements 9 and 10 detect simultaneously and electrically the pressure, flow velocity and flow rate of a sample fluid flowing into the chambers from the respective holes thereof.
