A flow regulator is disclosed for controlling liquid flow, for example, from a supply source to a receiving tank according to the liquid level in the tank. Specifically, a fluid interaction device communicating with the receiving tank causes a fluid pressure signal to be developed in response to departure of the liquid in the tank from a predetermined level. A differential pressure responsive valve adjusts liquid flow from the supply source to the receiving tank in response to the fluid pressure signal. Several embodiments and other features including a ...
A liquid level sensing system comprising: reservoir means having an inlet and an outlet and adapted for receiving a quantity of liquid therein; flow control means including a pressure responsive element for regulating flow at at least one of said inlet and outlet of said reservoir means according to a sensed pressure condition; and fluid amplifier means having serially aligned inlet, interaction and outlet zones comprising an inlet flow channel positioned above the desired liquid sensing level in said reservoir with the terminus of said flow channel appr...
