| 摘要 |
The invention relates to a switch-off valve for a fluid-conducting device of a commercial vehicle for interrupting and/or releasing a fluid flow of a fluid between a supply line and a spray nozzle. Further, the switch-off valve has a measuring device (92) for detecting the fluid flow, wherein the measuring device (92) has at least one first magnet element (80) and one second magnet element (84) for producing a common magnetic field (94). The magnet elements (80, 84) are arranged in such a way that the fluid can flow at least partially through the magnetic field (94). Furthermore, the measuring device (92) has at least one sensor (88, 90), which detects a charge displacement of charged particles in the fluid and which can output a measurement signal according to the charge shift. |
