FLOW-RATE SENSOR FOR A THERMAL FLOWMETER, CAPABLE OF ENHANCING THE RELIABILITY AND PRECISION OF MEASURING BY STRUCTURALLY ISOLATING A REFERENCE SENSOR AND AN ACTIVE SENSOR
PURPOSE: A flow-rate sensor for a thermal flowmeter is provided to replace and repair defective sensors individually by separating each sensor regardless of caliber, to which the thermal flowmeter is applied.;CONSTITUTION: A flow-rate sensor for a thermal flowmeter comprises a pipe(10), a body(11), a reference sensor(12), and an active sensor(20). The pipe supports each sensor and forms a path for connecting a lead line to a transmitter. The body connects the pipe to each sensor and supports them. The reference sensor is coupled to the body and measures the temperature of fluid. The active sensor is coupled to the body and measures the temperature of the body after being cooled by fluid, in which the heat of a heater(21) flows.;COPYRIGHT KIPO 2011
