FLEXIM FLUXUS PIOXS – Ultrasonic Clamp-on Liquid Flowmeter (Zone 2 Hazardous Area)


FLEXIM FLUXUS PIOXS Flowmeters – mainly used for concentration analysis during process control

FLEXIM manufacture market-leading ultrasonic flow meters – the FLEXIM FLUXUS PIOXS forms part of the permanent liquid flowmeter range.

Flexim FLUXUS PIOXS FlowMeter – Advantages


Flowmeters for Liquids & Gases

  • No downtime or maintenance thanks to non-intrusive design
  • Clamp-on design keeps installation time to a minimum and because the FLEXIM FLUXUS PIOXS has no contact with the media no special materials are required
  • Hygenic and highly dynamic flow measurement method, suitable for ultrapure media
  • No pressure loss, no risk of leakage, no contamination
  • No chemical compatibility issues, , watertight, no pressurized parts

Zone 2 Hazardous Area Flowmeter

Zone 2 Hazardous Area Flowmeter


Explosion Protection: ATEX (IECEx) Zone 2 and FM Class I, Div. 2 optional

What is Hazardous Area Zone 2?

  • Zone 2 Hazardous Area – a potentially explosive atmosphere in which an explosive liquid or gas atmosphere is not likely to occur in normal operation and if it occurs will exist only for a short time. “Short time” is not officially quantified according to IECEx or ATEX but commonly accepted by hazardous area industries as being prevalent for less than 10h/yr.


Flow Meter Applications

The FLEXIM FLUXUS PIOXS is the perfect solution for monitoring chemically aggressive and corrosive media in addition to ensuring all processes meet the correct standards regarding cleanliness, purity and protection from contaminates.
