Vega Isokinetic Sampling (VIS) – Accurate Multiphase Flowmeter

The new Vega Isokinetic Sampling (VIS) is a compact multiphase flowmeter that delivers high performance. The device is customized for wet gas applications, but can also offer excellent precision in complicated operating areas.

The VIS multiphase meter includes a number of unique features. For instance, the device is integrated with a dual inlet feature, through which turndown can be extended up to 100:1. This helps in maintaining the same level of precision.
