Funnel meter measuring device

A new measuring device can be used with compression sprayers. The sprayer has a tank that holds liquid, a pump that enables a user to compress air in the tank, a spray nozzle that is in fluid communication with the tank, an inlet opening to the tank, and a funnel surface that extends upwardly and outwardly from the inlet opening. A special gate fits onto a broken rim that extends upwardly from the inlet opening, and rotates between one position (in which liquid on the funnel surface flows into the tank through gaps in the broken rim) and another position (in which wall sections on the gate block the gaps). Markings on the funnel surface enable a user to measure a quantity of liquid that is retained on the funnel surface. Ribs and recesses on the broken rim and on the gate releasably, axially secure the gate to the broken rim.
