Product Description
Wedge Flowmeter Is Anti-blocking, Anti-pollution, And Precise In Measuring Industrial Fluids
The wedge flow meter is a high-precision flow measurement instrument based on the differential pressure principle. It measures flow by setting a V-shaped wedge as a throttling element in the pipeline and utilizing the relationship between the static pressure difference generated when the fluid flows through the wedge and the square of the flow rate.
- High precision and stability: After calibration, the accuracy can reach ±0.5%, with repeatability better than ±0.1% and excellent long-term stability.
- Wide range ratio: Typically 10:1 to 15:1, and up to 50:1 with special design.
- Low maintenance requirements: No moving parts, resistant to wear, and self-cleaning design reduces maintenance frequency.
- Low pressure drop: Permanent pressure drop is only 1/3 to 1/5 of that of orifice plates, resulting in significant energy-saving effects.
| Characteristics | Wedge Flow Meter | V-cone Flow Meter |
|---|---|---|
| Core Advantages | Resistant to clogging and erosion, suitable for ultra-high viscosity and solid-containing media | High precision, wide range, low pressure loss, and stronger versatility |
| Accuracy | ±1% ~ ±2% FS (relatively low) | ±0.5% ~ ±1.0% (high) |
| Range Ratio | About 3:1 (narrow) | 10:1 ~ 15:1 (wide) |
| Permanent Pressure Loss | Large | Small (energy-saving) |
| Applicable Media | Dirty, viscous, and thick media expert | Clean/dirty both acceptable, but more suitable for clean to moderately dirty |
| Cost | Simple structure, potentially lower cost | Complex structure, higher cost |
- Material Selection: Choose stainless steel (304/316), Hastelloy or PTFE-lined based on the corrosiveness of the medium.
- Wedge Ratio (H/D): Select according to the flow range, typically 0.45 to 0.85.
- Pressure Tap Method: Use standard threaded pressure tapping for clean media or remote flange pressure tapping for viscous/dirty media.
- Petrochemical Industry: Measurement of high-viscosity fluids such as crude oil, fuel oil, and chemical solvents.
- Wastewater Treatment: Wastewater and sludge containing suspended particles.
- Power and Metallurgy: High furnace gas, steam, circulating water, etc.
- Food and Pharmaceutical: Hygienic design suitable for easy cleaning and high-viscosity fluids (such as syrup).
The wedge flowmeter is a specialist in the differential pressure flowmeter family, excelling in handling challenging conditions. It trades off some accuracy, rangeability, and energy consumption performance for unparalleled anti-clogging and wear resistance. When your medium is highly viscous, prone to solidification, contains a large amount of solid particles or fibers, and the accuracy requirement is not extremely strict, the wedge flowmeter is often one of the most reliable and durable choices. Its value lies in its outstanding stability in harsh conditions and extremely low maintenance requirements.
