Abstract
A fluid dispenser comprising a fluid container and a metering unit is disclosed. The container comprises a fluid level sensor and the dispenser comprises a control unit configured to determine a parameter value representative for an amount of fluid in the container after refill on basis of a signal from the sensor. The sensor can for example be configured to generate a signal at a predefined fluid level (B, C), while the control unit is configured to calculate a fluid level on basis of an input value indicative of the fluid level (A) after refill, and a dispense value indicative of amounts of fluid dispensed since the latest refill. The control unit can be configured to compare the signalled predefined fluid level (B, C) with the calculated fluid level to generate a correction factor.
