Wedge Flow Meter
Wedge Flow Meter
Wedge flow meter is a new type of throttling differential pressure flow meter, suitable for high-precision measurement of high viscosity, low Reynolds number (≥500), large diameter and small flow conditions, with self-cleaning ability, no stagnation zone, wear resistance, and lower pressure loss than orifice plate.
- High-precision measurement for high viscosity, low Reynolds number (≥500) fluids
- Accuracy up to 0.5 grade, good repeatability
- Self-cleaning ability, no stagnation zone, not easy to clog
- Wear-resistant, long life, high reliability
- Permanent pressure loss lower than orifice plate
- Integral structure, no impulse piping needed for on-site installation
Overview
Product Overview
Wedge flow meter is a new type of throttling differential pressure flow measurement instrument, capable of high-precision measurement under high viscosity, low Reynolds number (≥500) fluid conditions. It plays an irreplaceable role in low flow velocity, small flow, and large pipe diameter applications. Mainly used for flow measurement of high-viscosity heavy oil, residual oil, diesel, oil, and various gases such as coal gas, hydrogen, nitrogen, air, steam, sewage, etc.
Measurement Principle
The measuring element adopts a special wedge throttling part. Fluid passes through without stagnation or blockage, with low pressure loss, and still achieves high-precision measurement at low Reynolds numbers. The integral structure requires no impulse piping for on-site installation.
