ABSTRACT:
This invention relates to a target flow meter and method of calibrating same adapted for use in various configurations of conduit and for movement from one conduit configuration to another comprising a housing connected to a conduit; a target means adapted for insertion into conduits for providing a constant centroid target area for the fluid relative to the conduit area for any level of fluid in a conduit; a meter body adapted for connection to the housing and for movement from one conduit to another; a mounting means for connecting the target means to the meter body for movement; force transfer means in relation to the target means for constant proportional transfer of force from the target centroid to the force transfer means in response to fluid level and movement in the conduit, and transducer means connected to the meter body for receiving the force transferred from said force transfer means and for measuring the fluid flow as a function of the force on the force transfer means; and further this invention relates to a method for calibrating a flow meter having a visually marked point in known relation to the centroid area of the target comprising attaching a force applying means to said visual marked point and applying a known force to the target at the known visual point on the target.
