  • Patent number: 9823107
    Abstract: Embodiments described herein include a system for insulating a flow meter that includes a thermal tube sensor housing. The thermal tube sensor housing may include a housing cavity that holds a sensor tube, a temperature sensor, and a heater for determining a flow rate of a fluid. In some embodiments, the heater imparts thermal energy onto the sensor tube. In some embodiments, the housing cavity additionally holds an insulator for reducing leakage of the heat from the housing cavity. In still some embodiments, the insulator includes a plurality of beads and a binder material.
    Type: Grant

  • Patent number: 9791307
    Abstract: Embodiments described herein include systems and methods for detecting flow of a fluid. One embodiment of a system includes a flow body, a thermal tube sensor housing, and a computing device. In some embodiments, the flow body includes an inlet for receiving the fluid and an outlet for expelling the fluid, the thermal tube sensor housing includes a sensor tube that includes a first connection portion and a second connection portion, and the sensor tube is configured with a cross position where a first portion of the sensor tube crosses paths with a second portion of the sensor tube, reducing a thermo-siphoning effect.
