The device operates as follows.

Suppose that when you turn on the device, the tank 1 is in the position shown in the drawing. In this case, compartment 2 is empty, and compartment 3 is filled with the measured medium. The emphasis 4, located on the tank 1, is supported by an electromagnet with windings 5 and 6, and an electromagnet with windings 7 and 8 is free. The power windings of the electromagnets 5 and 7 are energized from the power regulators 9 and 10 with a maximum current, designed to hold the capacitance 1 in this position when the compartment 3 is filled with material of maximum density. thirty

When the material in compartment 3 reaches a predetermined level, a signal appears at the output of level gauge 1, which is fed to the input of trigger 13, The signal of trigger 13 is fed to the input of program setter 15, which instructs the power regulator. material in compartment 3.

If the stop forces are equal, 4 breaks away from the electromagnet with windings 5 and 6, the material from compartment 3 pours out, and compartment 2 is placed under loading. At the moment the stop 4 is torn off, a pulse is generated in the control winding 6, which arrives at the trigger 13 and the program setter 15. According to this pulse, the trigger 13 sends a pulse through the set point 15 to the electronic pulse counter 17 and through the code-to-analog converter with the memory unit 18 ⁵⁰

V

........: -..... I '/ forces the flow meter 19 to work, and such switches off the program controller 15. In this case, the detachment stress of the stop 4, proportional to the weight of the material, is stored on the controller 9 and the winding 5 in compartment 3.

The voltage from the output of the power regulator 9 is supplied to the divider, where it is compared with the voltage at the constant current controller 21, and this comparison gives a signal proportional to the density of the measured material to the pointer 23. After that, compartment 2 is filled and the whole cycle is repeated.
