System introduction:
The system uses air as the medium, the critical flow venturi nozzle as the standard meter,
the vacuum pump in the system by way of producing negative pressure to conduct flow verification or testing on flowmeters.
The diameter sizes can be calibrated are DN15 to DN200 (up to DN400 later) , the flow range can be calibrated from 1 to 7,000 m³ / h (up to 10,000 m³ / h later ), and the device expansion uncertainty better than 0.3% (K = 2).
System Features:
1.The whole system device, with compact struction, high accuracy, good repeatality and stability.
2. The nozzle structure is simple, durable, with long verification cycle (5 years a time), its discharge coefficient uncertainty ≤ 0.2%.
3. Wide test diameter, large test flow, the meter is easy to install (Pneumatic clamping device).
4. All stainless steel pipe, with long service life.
5.
