Request Information Favorite
The Model SL-900 Series Ultrasonic Micro-measurement System is an ideal solution for the detection and measurement of ultra-pure chemical fluids in the semiconductor industries.

The SL-900 Series provides single or multiple discrete point levels with a very high degree of precision. The SL-900 Series ultrasonic system is well suited for high viscosity liquids such as DMAH, titanium precursors and copper precursors.
Features
  • 316L stainless steel machined sensor body
  • Sensor material has an electropolished finish (Ra = 25 μin – minimum)
  • Miniature sensor size reduces liquid
  • Volume displacement
  • Works with the following chemicals independent of dielectric, viscosity, color, density and opacity of chemical fluids: DMAH, TAETO, CVD, TDEAT, CUTMUS, TEOS, DCE, TCA
  • High pressure vessel application up to 250 psig (1724 kPa) (consult factory for higher pressure applications)
  • Accuracy of each discrete point level is ±2 mm
  • Repeatability of ±1 mm is typical
  • Single point low level as close as 1/4" (6 mm) from bottom of vessel for 5/8" tube and 5/16" for 1/2" tube
