AI Technical Summary

Technical Problem

Existing flow meter calibration devices cannot determine whether the connection between the flow meter under test and the calibration pipeline is tight, which causes the flow meter test results to be affected by loose connections.

Method used

A liquid flow meter calibration device was designed. By setting a second standard meter and the meter under test to measure the flow rate, and combining the commutator, level gauge and humidity detection probe, the sealing performance of the connection between the flow meter and the calibration pipeline is judged, and the sealing groove and sealing gasket are used to ensure the sealing performance of the connection.

Benefits of technology

It effectively eliminates deviations in flow count values ​​caused by unsealed connections, ensuring the accuracy of test results, providing a judgment on the sealing of the connection between the flow meter and the calibration pipeline, and improving the reliability of the test.

Abstract

This utility model discloses a liquid flow meter calibration device, belonging to the field of flow meter calibration technology. The device includes a water tank, a water pump, a measuring pipe, and a controller. The water tank and the water pump are connected via the measuring pipe, which includes a calibration pipe. The calibration pipe is equipped with a second standard meter for measuring the flow rate within the calibration pipe and a test meter for measuring the flow rate within the calibration pipe. A pipe joint is provided on the calibration pipe. This utility model provides a liquid flow meter calibration device that can determine whether the connection between the test meter and the calibration pipe is sealed, avoiding deviations in the test meter's readings due to liquid seepage at the connection. It also eliminates numerical errors caused by unsealed connections between the test meter and the calibration pipe, helping testing personnel to accurately measure the actual flow rate of the test meter.
