Deep-well thermal flowmeter
A flowmeter is described for measuring the flow rate and direction of a fluid flow, said flowmeter comprising: thermopulse producing means for heating a portion of the fluid flow to thereby produce a thermopulse in the fluid flow which travels along with the fluid flow, thermopulse detecting means for detecting the thermopulse in the fluid flow, said thermopulse detecting means including first and second temperature sensing means disposed in the fluid flow on opposing sides of, and at known distances from, said thermopulse producing means, and support means for mounting said first and second temperature sensing means and extending parallel to the direction of the fluid flow such that dispersion of the thermopulse within the fluid flow resulting from turbulence therein caused by said support means is minimized, and timing means for measuring a time interval between the production of the thermopulse and the detection thereof by said detecting means, said time interval being representative of the flow rate.
