A valve and coacting control circuitry for filling variously sized and shaped receptacles to an exact settable level with a relatively high impedance fluid such as maple syrup. Errors caused by bubbles are avoided by controlling the flow rate through a shaped orifice for essentially laminar flow. Dripping is eliminated by shaping the exit orifice to prevent gravitational emptying of the faucet cavity when the valve is closed. Sensing of the fluid is accomplished with a flexible wire probe, not sensitive to the receptacle shape but may be adjusted to a desired height, connected to a sensitive electronic circuit with a very high input impedance which allows sensing a voltage through the high impedance fluid. Once started, the filling process need not be monitored by an operator who is then free to do other tasks.

A device for filling an open variably shaped receptacle, with an opening, with fluid to a desired level, comprising: a faucet connected operably to a supply tank of said fluid, said faucet internally designed to allow essentially laminar exit flow of said fluid, said faucet having a valve to control the flow of fluid through said faucet, a latch means with one or more steps operable to hold said valve open to one or more of a multiple of degrees compatible with a desired setting of laminar flow of said fluid, an electromagnetic solenoid operably connected to said latch means operable to release said latch means thereby closing said valve and stopping the flow of said fluid, a height adjustable probe means positionable in said variably shaped receptacle opening, an electrical source means having one pole electrically connected to said fluid supplied to said faucet and the other pole connected to said probe means, and a circuit means connected to be actuatable by said electrical source means when said probe means contacts the rising said fluid in said receptacle and operable to control said solenoid to release the latch means and thus close the valve.
