Product Description

Gas flow calibration equipment of DN15 to DN1200 atmospheric pressure sonic nozzle method and microcomputer automatic control system
 

Introduction:
 The system uses air as the medium, the critical flow venturi nozzle as the standard meter, and the flow meter is verified or tested by means of a vacuum pump to generate negative pressure in the system. The calibration diameter is DN15-DN200 (later can be extended to DN400), the test flow range is 1-7000m3/h (later can be extended to 10000m3/h), and the device expansion uncertainty is better than 0.3% (K=2)


Main technical parameters:
- Calibrated caliber size: DN15~DN1200
- Calibration method: sonic nozzle method
- Uncertainty of equipment expansion: master meter method  0.33%,0.5%
- Gas source pressure: ≤0.1MPa;
- Structural style: tiling

Main technical features:
- This calibration equipment is applied to the calibration of flowmeters of which medium is atmospheric pressure air;
- Sonic nozzle is adopted as the standard;
- Compact structure with high accuracy, repeatability and stability
- The nozzle structure is simple, sturdy and durable, of which a long calibration period (every 5 years).
- The equipment has a large calibration caliber to get a large calibration flow, and it's easy to install (pneumatic meter clamper) meters calibrated
- All stainless steel pipe, long service life
- Customers can freely choose the calibration time, calibration volume, flow points, calibration times, etc. of the flowmeters calibrated, which is very convenient for users to operate
-The software is easy to operate and has operating authority. Users can configure the content in the database according to the actual situation.
- Control and data acquisition adopt integrated design for microcomputer and lower machine, data can be transmitted remotely.
