ABSTRACT:
A flowmeter sensor includes a sensor tube, and a heater/resistor through which the sensor tube passes. The heater/resistor includes a substantially cylindrical sleeve fitted around the sensor tube and made of ceramic. A thin film of platinum is deposited on the sleeve and is then partially removed by a laser to provide a helical resistance pattern. A pair of electrically conductive rings are tightly fitted around opposite ends of the ceramic sleeve and serve as bases to be connected with a corresponding pair of leads.
