VFM glass flow meter

Features of the VFM Glass Flow Measuring System

The VFM system is used to measure molten glass to monitor and control the production process. When used in conjunction with an appropriately configured bushing controller, the glass flow rate can be adjusted to an accuracy of ±0.4% by weight. With proper control, the weight of the final product can be reduced by approximately 3-5%.

Non-contact, continuous measurement

Calculates flow rate by measuring fibre diameter and velocity

Feedback from controller

Automatic bushing control by 4-20 mA signal

Temperature measurement

Reduces errors in automatic control of draw speed

Reduces product weight (approx. 0.5%) due to stable control

Contributes to longer spinning machine life due to stable fibre supply

Contributes to rapid pull speed changes over a wide range

Increased productivity due to reduced manual handling

Reduced defects due to poor quality products and savings in binder usage

Extended furnace and forehearth life due to stable pull speeds

Increased productivity, profitability and product quality
