Abstract
A flow sensor includes a tube having a tube wall with a window in it. A thermally-conductive base covers the window and has mounted to it a heater and a sensor of a hot film anemometer flow sensor. The base is sealed to the window to resist leakage of fluid from the flow path through the window under normal operating pressures. The hot film anemometer flow sensor is used to measure fluid flow through the tube.
