DEVICE AND A METHOD FOR MONITORING THE FLOW OF LIQUID OR SOLID MEDIA, IN PARTICULAR SAND, CONVEYED BY MEANS OF COMPRESSED AIR, GRITTING DEVICE FOR VEHICLES AND VEHICLE HAVING SUCH A GRITTING DEVICE

摘要

Device (10) for monitoring the flow of liquid or solid media, in particular sand, conveyed by means of compressed air through a discharge line, comprising a gas line (16) which can be connected to a compressed air source (14), a container (20) for the medium to be conveyed, a mixing chamber (22) which is connected to the gas line (16), to the container (20) and to the discharge line (12) and into which, during the operation of the device, medium can pass from the container and can then be transported away from the mixing chamber (22) through the discharge line (12) by the compressed air, a pressure sensor (18) for monitoring the pressure in the gas line (16), an evaluation unit which is coupled to the pressure sensor (18) and has the purpose of evaluating signals generated by the pressure sensor (18), and means which are coupled to the evaluation unit and have the purpose of outputting information about the flow of the medium.
