Acuity proudly features Jacoby Tarbox sight flow indicators and sight glass windows from Clark Reliance. For process viewing in biopharma, food / beverage, high-purity chemical and other hygienic applications, we commonly recommend the Jacoby Tarbox Hy-Sight Sight Flow Indicator and Uni-San Hygienic Sight Window.

Hy-Sight - Sight Flow Indicators

sight flow indicator - sight gaugeHy-Sight is a revolutionary visual-flow indicator that has been perfected and refined over many years for maximum performance in hygienic applications such as bioprocessing, food / beverage processing, high-purity chemical manufacturing, cosmetics and other applications where performance and cleanability are paramount. With potentially thousands of connections in your facility that are not internally visible, the Hy-Sight can allow operators to observe critical details inside their process such as color changes, phase changes, cleanliness or to avoid pump-cavitation. The standard materials are annealed borosilicate glass and stainless steel, but alternatives such as Hastelloys, Monels, or other engineering metals are also available.

Cleanability Matters!

Traditional sight-flow indicators have up to 5x more intrusion in to the flow path vs. Hy-Sight which can lead to trapped particles and inferior cleaning cycles. Whereas the positive stop design, ACME threads, and locating o-ring of the Hy-Sight work together to minimize o-ring intrusion and maximize cleanability. Avoid unwanted hold-up material in your sight-flow indicator by specifying the Hy-Sight.

Hy-Sight Features and Benefits

  • 316 Stainless Steel with other specialty metals available
  • Annealed borosilicate glass (the best material for process viewing)
  • Positive stop design, ACME threads, and locating o-ring work together for proper o-ring seat
  • Compatible with CIP and SIP
  • Cleanest glass to metal transition point vs. other sight flow indicators
