Quadbeam S20 Hygienic Suspended Solids Sensor can help Dairy Plants increase Yields & Efficiency!

Quadbeam Technologies S20 Hygienic Suspended Solids Sensor

Locating the exact point of transition between product and water or different products can be challenging with many plants relying solely on time and flow calculations.

A Quadbeam Sensor will quickly and accurately identify the interface time after time which could mean any or all of the following to your process:

  • Faster Change Times giving to reduced down time
  • Increased Yields
  • Decreased waste treatment
  • Decreased water consumption

With the use of a Quadbeam sensor you get to change at the actual point you want to, not a theoretical point.  Quadbeam’s four beam ration metric technology self compensates for change caused by contamination or sensor surface or aging of the instrument.

Application:  Gypsum Slurry at a Generating Station

For corrosive applications, both the choice of lining material and the method of lining are critical considerations.

PFA lining material is melt-processible, meaning that this lining material can be locked to the valve body and plug using cast-in dovetail recesses and machined grooves.  (PTFE cannot be locked in.)

  • PFA Temperature range is rate to 400°F
  • Chemical inertness
  • Excellent permeation resistance
  • Low coefficient of friction
  • Toughness
  • Flexibility
