Definitions
- the invention relates to a method and a device for determining material properties of liquids.
- the invention has for its object to describe a method and an apparatus that are required for wide areas of industrial use of liquids
- Measurements and monitoring measures can be used to ensure the quality assurance and control required in industrial production and processing.
- Fig. 1 is a block diagram of a measuring device for performing the method and is connected;
- the system Fig. 1 consists essentially of an ultrasound probe 3, which is used in a container 1 for the liquid to be monitored, and a monitoring device 2, which is set up at a suitable distance and contains an electronic evaluation circuit with the necessary power supply.
- the container can be a transport container or a tank truck, or a storage container of a stationary type as a link in a production or storage system. It is also conceivable that several containers are provided, each equipped with an ultrasound probe 3 and connected to the evaluation circuit.
- the ultrasound probe 3 (FIG. 2) arranged in the container consists of a sound guide tube 9 which is connected to a connecting flange e.g. is attached to the cover of the container 1 and ensures with openings in the jacket that the liquid in the sound guide tube 9 assumes the same level as in the container.
- the length of the sound guide tube 9 is dimensioned such that its lower end is at a short distance from the container bottom 13.
- Ultrasonic sensors 5; 7 each have an ultrasound transmitter and an ultrasound receiver and enable an accurate height and distance measurement from the transit time of the sound pulse or the echo.
- ultrasound sensors of the working principle can also be provided that the transmitter automatically switches to reception after the pulse has been emitted
- the sound guide tube 9 is equipped with several reference marks 11 and thereby enables the speed of sound between the first ultrasonic sensor 5 and the To measure reference marks 11 and the sound wave resistance and to calculate the density of the liquid in the evaluation circuit of the monitoring device 2 from the measured values.
- a temperature sensor 15 is additionally provided in the lower region of the sound guide tube 9.
- the special tank curve is determined once, which indicates the filling volume as a function of the height of the liquid level and is available in the memory of the monitoring device.
- Standard material properties of the liquids to be monitored in each case are available so that from the measured values determined, in particular the density, to specific properties, such as concentration, e.g. of fat, sugar, water content or the like, impurities or faults can be quickly recognized in this way.
- concentration e.g. of fat, sugar, water content or the like
- impurities or faults can be quickly recognized in this way.
- energy parameters e.g. Octane number, calorific values are checked or monitored.
- the continuous monitoring of the liquid level also allows a precise control of the consumption or access of liquid quantities as well as a quick determination of leaks or malfunctions.
