FIELD: measuring equipment.
SUBSTANCE: invention relates to a device, a node, and a method for determination of a liquid volume in a fluid sample. The device contains a cell having an upper part formed by a tubular sidewall and a lower part formed by a closed end. The lower part has a conical shape and forms a chamber made with the possibility of reception of liquid. A piston having an upper part and a lower part is described. The piston is made with the possibility of sliding in the cell and sealing of the cell in a gas-impermeable way. The lower part of the cell contains at least one label on a peripheral surface of the conical closed end.
EFFECT: creation of a device for measurement of a liquid volume in a hydrocarbon fluid sample, allowing for effective measurement of a liquid volume with high accuracy even for small liquid volumes.
