Liquids

Which measuring principle fits your application? In 5 guided selection steps you will always find the right measuring instrument.

Select your measurement application

Horizontal cylindrical storage tank

  • Calm surface(e. g. bottom filling, filling via immersion tube or rare free filling from above)
  • Accuracy 3 to 10mm/0.12 to 0.4″
  • Measurement without stilling well top mounted
  • Tank diameter up to 3m/9.8ft
  • Changing media
  • Installation from above

Vertical storage tank

  • Calm Surface (e. g. bottom filling, filling via immersion tube or rare free filling from above)
  • Accuracy 3 to 10mm/0.12 to 0.4″
  • Measurement without stilling well/bypass

Buffer tank

  • Agitated surface (e. g. permanent free filling from above, mixing jets, slowly turning mixer, lateral installation)
  • Measurement without stilling well
  • Foam spots, islands
  • Pressurized
  • Fast temperature changes (cleaning)

Recipient tank (e. g. bottling facilities)

  • Pressurized
  • Fast temperature changes (cleaning)
  • fast filling and discharging operations
  • Tank <1m/3.2ft in height
  • Strongly foaming surface

Process tank with agitator

  • Agitated surface
  • Single-stage agitator (< 60 RPM)
  • Pressurized
  • Free space measurement (without stilling well/bypass)
  • Foam formation is possible depending on the application

Stilling well

  • Measurement in metal pipes (installed in the tank) e. g. immersion tube
  • Nominal width typ. DN 40 to DN 150/1.5″ to 6″

Bypass

  • Measurement in metal pipes (installed outside the tank)
  • Replacement of the displacer or float vessels, compensation vessels
  • Nominal width typ. DN 0 to DN 150/1.5″ to 6″

Pump shaft/ overfall construction/ rain water basin

  • Many obstacles
  • Risk of flooding, foam formation, and turbulent surfaces
  • Build-up on the sensor and the contacting obstacles (ice formation in water, suspended solids)
  • Installation at the open basins or the underground
  • Sludge formation due to suspended solids

Channel measurement (free flowing)

  • Risk of flooding, foam formation
  • Obstacles
  • Condensate formation (icing in winter) on sensor and instrument
  • build-up on the sensor and contacting obstacles (ice formation in winter, suspended solids)
  • Installation at open basins or underground

Interface measurement

  • Interface liquid/liquid
  • With emulsion layer
  • Multiphase measurement
