MULTI VOLUME TANK PROVER |
摘要 |
The present invention relates to a multi-volume reference tank. The volume of the multi-volume reference tank is changeable to a volume necessary for calibration using one reference tank without a need for multiple volume reference tanks, thereby saving costs and enabling exact check on the remaining amount of a fluid and fine calibration. The multi-volume reference tank for calibration of a fluid measuring instrument includes: a reference tank fixing unit; a reference tank adjusting unit which is connected to be inserted into the reference tank fixing unit and moves up and down to adjust the volume of the reference tank; a volume control unit which controls the up and down movement of the reference tank adjusting unit; a drain valve which is installed in the lower part of the reference tank fixing unit and discharges the fluid inside the reference tank; and a zero adjusting unit which sets the remaining amount of the fluid inside the reference tank to a zero point which is a preset volume. |
