FIELD: measurement equipment.SUBSTANCE: in method of measurement of liquid parameters the difference between the gravity and the floating force of partially submerged buoy is measured, the angular movement is formed by means of action of forces on arms of the angular hinge having orthogonal load, the conversion of angular movement into an electric signal is performed the value of which is used for determination of integrated density, the signal proportional to liquid level from the tank bottom, is measured separately, the liquid volume in the tank is determined, which being multiplying by integrated density gives the mass of liquid in the tank. Into the device for measurement of liquid parameters in the tank, containing the buoy and the microcontroller, the angular hinge, which fitted with a hinge rotation angle sensor and orthogonal load, and also the level gage are added. The buoy is fixed on the angular hinge, and outputs of the rotation angle sensor and the level gage are connected to the microcontroller.EFFECT: minimising errors of measurement of integrated density and liquid level in the tank.2 cl, 2 dwg |
