O-ring flowmeter

The Variflux 6000 O-ring flowmeter features an L-shaped sealing ring with a uni-directional trapezoidal lip which, unlike regular O-rings, eliminates the problem of bacteria growth by preventing expansion of the rubber seal into the measuring tube.

Suitable for a broad variety of duties from ultra-precise batching to flow measurement in large-scale production plants, Variflux 6000 boasts an ultra-smooth measuring tube liner made from US FDA-approved teflon-PFA, which allows for easy and effective cleaning and prevents the build-up of bacteria.

The liner is chemically and mechanically extremely stable.

It is completely CIP- and SIP-proof, and all wetted parts of the meter are made exclusively from US FDA-approved materials.

The fully welded stainless steel housing of the Variflux 6000 is designed for easy cleaning and ensures high resistance to corrosive attack from even the most aggressive cleaning agents. All other parts of the meter in contact with the flow are also manufactured from sterile materials such as stainless steel adapters and hastelloy C4 or stainless steel electrodes.

The measuring tube liner is reinforced with a stainless steel mesh which guarantees accurate results even under varying pressure and temperature conditions, and provides full vacuum resistance up to process temperatures of 180°C. Calibration on test rigs with less than 0.03% uncertainty contributes to the high accuracy and repeatability of the meter.

Variflux 6000 meters are available in an extensive range of sizes thus allowing a full-scale of flow rates from a few litres per hour to 750 m3/h.
