Closed agricultural field spraying system

摘要

The system has a fluid tank (1) and an additional container (2), which are connected with each other over a piping system. An electrical switchable medium (18) is provided for switching-on and switching-off a discharge device (12) that transfers and/or circulates a fluid between the tank and container. An electronic sensor unit (24) is provided for detecting the fluid condition in the tank and container and for transmitting signals to a processor unit (22). Fluid level data is computable from the signals. The switchable medium is controlled by the processor unit based on the computed data.
