<p>The invention relates to a process for monitoring tank interior cleaners driven by a cleaning agent, that have a rotating body that forms part of the supply path and which have at least one output nozzle, and which indicate the completion of each complete revolution of the rotating body. The rotation time of the rotating body for each full revolution is monitored so that this is represented in the time interval between two voltage pulses, in which connection the final voltage pulse serves as a reset pulse for the monitoring time resulting from the demand for an adequate cleaning effect, this being greater by an adjustable percentage amount than the nominal time for a revolution of the rotating body, and in that for the case that the rotation time is greater than the monitoring time, an electrical and/or visual malfunction signal will be initiated.</p> |
