ISO 9001/14001 Certified Manufacturer
ISO 5167-4 Standard Venturi Flow Meter
Classic Venturi design offering low pressure loss and high accuracy
The Venturi tube, developed by Clemens Herschel in 1887, has been recognized as one of the most reliable flow measurement devices. Its unique convergent-divergent structure results in very low pressure loss, making it ideal for applications where energy efficiency is critical.
Pressure loss 10-15% (70% reduction vs orifice)
Compliant with ISO 5167-4 and ASME MFC-3M standards
High accuracy within 0.5%
Long-term stability - over 20 years service life
