FIELD: measuring technology. ^ SUBSTANCE: invention aims at measuring the liquid density. A weight densimetre comprises a loop U-pipe cantilever fitter on flexible cuffs, a travel transducer and a spring connected to the loop U-pipe. Besides the weight densimetre comprises a wound permanent magnet, a reference load, a first key, an electric drive, a second key and a computing control unit. And the permanent magnet with the pulled-up reference load is rigid over the loop pipe. And the electric drive is mechanically connected to the spring. Besides an output of the travel transducer is connected with an input of the computing control unit with its first and second outputs connected to driving inputs of the first and second keys. The winding of a permanent magnet and the electric drive through the first and second keys are respectively connected to the power supply, and information output of the densimetre is a third output of the computing control unit. ^ EFFECT: higher accuracy and operability of the weight densimetre. ^ 1 dwg |
