Abstract
An apparatus and method are provided for measuring the flow rate of liquid developer in a diazotype copy machine. The liquid developer is supplied from a supply source to a flowmeter provided with a metering device for dispensing the liquid developer from the flowmeter to a reservoir mounted on the flowmeter. A valve is associated with the reservoir and is actuable between a closed condition for retaining the liquid developer in the reservoir and an open condition for draining the liquid developer from the reservoir. An indicator is provided on the reservoir for measuring the flow rate, subsequent to actuation of the valve from the open to the closed condition, and provides an indication of the quantity of liquid developer received by the reservoir relative to a predetermined time period.
