ABSTRACT:
A flow rate measurement apparatus is comprised of a generally cylindrical tubular main body introduced transversely of the main duct through which flows a fluid whose flow rate is to be measured. A first conduit for measuring the total pressure and a second conduit for measuring the static pressure are introduced along the upstream and downstream sides of the interior of the tubular main body, respectively, while coolant water inlet and outlet pipes are also introduced into the mid portion of the interior of the main body for circulation and cooling. Dust and dirt entrained in the fluid and introduced into the first and second conduits descends by gravity so as to be collected in associated dust boxes for removal.
