An intelligent instrument and meter calibrating device

Abstract

This utility model relates to the field of instrument calibration technology and discloses an intelligent instrument calibration device, including: a water tank; a flow pipe connected to the water tank via a water pump; a return pipe connected to the other side of the water tank; a first water pipe and a second water pipe equally spaced between the flow pipe and the return pipe, the first water pipe, the second water pipe and the flow pipe having different inner diameters; the water pipes are connected by a connecting mechanism. When the water pump is started, water inside the tank flows sequentially into the flow pipe, the first water pipe, the second water pipe and the return pipe. At this time, the flow rate inside the three water pipes is detected by three instruments to be tested, and their readings are observed to see if they are the same. Then, the positions of the three instruments to be tested are changed, and the readings are observed again. Finally, the above operation is repeated. By changing the positions of the three instruments to be tested, the accuracy of the instrument readings under different flow rates is verified, thereby improving the accuracy of the instrument testing.
