achieve accurate flow control with Veco’s flow discs.
A flow disc is a thin metal part with micro apertures to accurately control flow stream. It is widely used in flow meters/regulators that require high accuracy of dispensing control, e.g. flow regulators for medical dispensing, flow meters for industrial gas control, etc. Quality and accuracy of the orifice disc is of key importance in any flow regulating/measurement system since it determines the dispensing control of the whole system: A 5% variation of a hole diameter could result in a 10% variation of the flow quantity.
Electroforming is known as the perfect fabrication method for high accuracy flow discs with custom design patterns. Hole geometry is in perfect control which enables accurate and consistent dosing performance. The award-winning thermal mass flow meter which we have developed with our customer incorporates a high precision laminar flow element solution with an integrated turbulence filter for mounting inside a fluid flow channel. This element is constructed with piled-up plates with inflow and outflow openings which incorporate grooves and channels.
