Arrangement for monitoring the useful properties of fluids
 An arrangement monitors the useful properties of pressure fluids (5) in fluid-technical installations. A plurality of measured variables, each representing a useful property of the pressure fluid, are determined by a plurality of sensors (13, 15, 17) which are combined with a pump (11) to form a structural unit which can be build into a tank (3) containing the pressure fluid. The sensors (13, 15, 17) are hydraulically connected in series with the pump (11).
