Project Name: Standard Method for Liquid Small Flow by Mass Method

The main technical parameters: Device expansion uncertainty: 0.05% (electronic scale uncertainty 0.02%) (K = 2)

Test pipeline range: DN4 ~ DN50

Flow range: 0.04-30m3 / h

Project description: This project is a set of standard liquid (water) small flow device based on mass method built by Shenyang Metrology and Testing Institute. Complete structure mining
Designed with skid-mounted structure. The liquid source uses a water pump and enters the test tube section through a pressure-stabilizing container. All adopt microcomputer automatic control, can carry out a variety of small
Verification of caliber flow meters.

Project Name: Oil Flow Standard Device (Vehicle / Base Type Volume Tube)

The main technical parameters: Verification method: standard volume tube method + standard table method

Device expansion uncertainty: standard volume tube method: 0.05%, standard table method: 0.20%

Covered calibration caliber: DN15-150

Flow range: 0.15 ~ 180m3 / h

Project description: This project is a vehicle-mounted / base-type standard volumetric tube oil flow standard device constructed by Shenyang Metrology and Testing Institute according to needs. The
The device adopts a tiled structure, and the volume tube can be used fixedly or the carrier can be used on site. Hose connection to the instrument under test
The way. The oil flow standard device is explosion-proof and has no hidden dangers. The verification process is all computer controlled. Standard flowmeter uses combination
Method, its accuracy is greatly improved.
