Abstract: Tally means for a liquid dispenser which selectively draws measured quantities of liquor for discharge through a discharge sprout. A liquid pressure responsive sensor is connected to the discharge line and is responsive only to passage of liquid. The sensor has a chamber with a diaphragm closing one end. A chamber inlet, larger than the outlet, leads through the end closed by the diaphragm. Because of differential in orifice size, liquid accumulates in the chamber causing the diaphragm to deflect but not respond to air flow. A piston in the chamber is moved by the diaphragm to actuate a tally apparatus to provide both printed record and a display of the number of drinks dispensed.
