Abstract
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).
Claims8
An arrangement for monitoring useful fluid properties, comprising:
- a container containing a fluid to be monitored and having a container opening;
- a tubular frame extending through said container opening and into said container for immersion in said fluid, said frame having frame openings for said fluid to pass therethrough;
- a fluid pump with a driving motor mounted on said frame and immersed in said fluid;
- a sensor block housing and integrating a plurality of fluid property sensors and flow channels connecting said sensors in series with one another and with said fluid pump, said sensor block being mounted on said frame and immersed in said fluid;
- and
- a sensor attachment plate bar arranged within said frame, carrying an electronic assembly for processing signals from said sensors, and immersed in said fluid.
