Apparatus and method for monitoring the flow of conveyed by means of compressed air liquid or solid media, in particular sand, the sand spreading device for vehicles, and vehicle with such a the sand spreading device

摘要

The apparatus (10) for monitoring the flow of by means of compressed air by means of a discharge line is being transported liquid or solid media, in particular sand, comprising a with a compressed air source (14) to the gas line (16) which can be connected, a container (20) for the medium to be conveyed, to the gas line (16), the container (20) and the discharge line (12), which is connected to the mixing chamber (22), into which, in the operation of the device medium from the container and then pass from the mixing chamber (22) of the compressed air through the discharge line (12) can be transported off, a pressure sensor (18) for monitoring the pressure in the gas line (16), a with the pressure sensor (18) coupled to the evaluation unit for evaluating of the pressure sensor (18) and signals generated which is coupled with the evaluation unit comprises means for outputting of information via the flow of the medium.
