Abstract
A valve unit may include a valve and a sensor assembly coupled to the valve. The valve may include a check disk configured to move along a pre-determined path to contact a valve seat in a closed state and configured to decouple from the valve seat in an open state. The valve may also include a mechanism to restrain lateral movement of the check disk to prevent the check disk from sticking. The sensor assembly may include a position sensor configured to generate a first electrical signal related to movement of the check disk and may include circuitry coupled to the position sensor. The position sensor assembly may generate a reference signal to eliminate noise within the first electrical signal. The circuitry may determine fluid flow parameters including flow volume of liquid components and of gas components of the fluid mixture based on frequency components within the first electrical signal.
