Sulphuric Acid Mass Flow, Concentration & Density Meter

Non-invasive Mass Flow, Concentration and Density Measurement of strong Sulphuric Acid and Oleum

By measuring non-invasively from the pipe wall outside and never being in direct contact with the medium flowing inside, PIOX S721 SA is the ideal solution for monitoring strong sulphuric acid and oleum:

The system measures sulfuric acid concentration and mass flow directly on the main production lines (concentration range of 80% to 100%)
It accurately determines the acid strength in real time
It significantly increases plant safety and availability as it does not require any pipe opening or welding for installation nor any additional flanges
The measurement is free of wear or abrasion and thus also virtually maintenance free
It can never be a source for potential leaks and sub-sequent process shut-downs

Applications / metering points of PIOX S

Solutions for Sulphuric Acid and Oleum Producers and Demanding Industries

Advantages

Extreme reliability due to no direct contact with the medium
Highest accuracy over a wide flow, concentration and temperature range (up to 400 °C)
Increased plant safety and availability - no pipe works or process shut-downs required
Certified for usage in hazardous areas (ATEX, IECEX Zone 1/2 and FM Class I, Div. 1/2 certified)
