Abstract:
A flow control valve assembly has at least one manifold having an inlet flow port, an outlet flow port, and a flow channel provided there between, the flow channel having an inlet chamber, a variable area chamber and an outlet chamber, with fluid flowing from the inlet flow port to the inlet chamber, the variable area chamber and the outlet chamber, in that order, before exiting the outlet flow port. The flow control valve assembly further includes a float assembly having a float extending through the flow channel and which is limited for its movement inside the variable area chamber, a connecting rod extending through the flow channel and which has an upper end that is connected to the float and a lower end that is connected to a magnet. A measuring device is positioned outside the fluid chamber at the bottom of the at least one manifold, and spaced apart from the magnet.
