ABSTRACT:
A method and apparatus for monitoring and calibrating fluid flow through a conduit comprises sliding a control plate into the conduit and restricting the flow of fluid through the conduit so as to determine the minimum acceptable flow. The position of the control plate at minimum acceptable flow is determined, following which the plate is removed from the conduit. At periodic intervals the control plate again may be slid into the conduit to ascertain whether the acceptable minimum flow has changed, thereby verifying acceptable fluid flow and enabling remedial measures to be taken if the fluid flow has deteriorated.
