Abstract
A flowmeter of the thermal type, having a heated flow-sensing probe and a temperature-sensing reference probe, in which the flow is passed through nozzles to form two jets and those jets are directed at the heated portion of the heated probe and the temperature-sensing portion of the reference probe, while flow around the supporting portion of the heated probe is minimized. Such a flowmeter allows low gas flows to be measured without the use of capillary elements that are subject to plugging and can create unwanted pressure drops.
