Henan Institute of Metrology (National Water Meter Verification Center)

Project Name: Standard Gauge + Volumetric Water Meter Standard Device

The main technical parameters: Standard table method for device expansion uncertainty: 0.2% (standard table uncertainty 0.2%)

Volume method: 0.05% (indicator uncertainty 0.025%)

Test pipeline range: DN15 ~ DN600

Flow range: 1-2000m3 / h

Project description: This project is a comprehensive water meter verification device that integrates standard meter method and volume method.
. The circulating medium is clean water. The whole device uses two standard devices for comparison. The device is divided into two sets of independent structures, one set is DN15-50
Water meter verification device; a large-caliber water meter verification device for DN80-600. The liquid source uses a water pump, and enters the test through a pressure-stabilizing container and filter.
Inspection section. All the devices adopt microcomputer automatic verification control system, which is easy to operate, stable and reliable. Not only verification of water meters, but also development
Verification of other liquid flow meters.
