Abstract

The invention relates to the technical field of water meter testing, and specifically discloses a large-flow ultrasonic water meter calibration platform, including: a pumping pipeline, a constant pressure pipeline, a flow calibration pipeline, a test tooling platform, an adjusting pipeline, a first collection pipeline, The second collection pipeline, the flow conversion device, the metering water tank, the third collection pipeline, the first drop water tank and the return water pipeline. The invention can switch between the standard meter calibration method and the static mass calibration method to calibrate the water meter, widen the accuracy range of the measured water meter, and also through the parallel connection of multi-type pump water pipelines and multi-type flow calibration pipelines Parallel connection, multi-type parallel connection of regulating pipelines and multi-type metering water tanks provide different types of calibrated meters with corresponding environments during calibration, and improve the compatibility of the calibration platform.

Description

technical field [0001] The invention belongs to the technical field of water meter testing, in particular to a large-flow ultrasonic water meter calibration platform. Background technique [0002] A water meter is a meter used to measure water consumption in residential water and municipal water. After years of development, water meters have evolved from the original mechanical water meters to various types of water meters. Among them, ultrasonic water meters are characterized by their high accuracy and reliability. Good performance, wide range, long service life and other advantages are favored by the majority of users, but because the ultrasonic water meter is too sensitive, the test water pressure and test flow required for the factory test need to reach a certain stability before the water meter leaves the factory. Calibration tests are more accurate. For the calibration test of large-flow ultrasonic water meters, the investment cost of the test bench is relatively larg...
