  • Thermal flowmeter
    Patent number: 10240956
    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.

  • Thermal-type flowmeter having separate probe mounting arrangement, a mechanical mounting structure, and valves for each probe
    Patent number: 9664544
    Abstract: A flowmeter of the thermal type, having a heated flow-sensing element and a temperature-sensing reference element, the elements constructed and arranged to be installed in a pressurized pipe. The flowmeter has one probe with the heated element and a separate second probe with the reference element. The probes are constructed and arranged to pass through the pipe wall in separate through-holes. There is a mounting structure such as a split ring that is adapted to be mounted to the pipe. Two valves operatively coupled to separate locations of the mounting structure, where one probe passes through each valve and into the pipe.
