Sight-Flow Indicators & Sight Glass Windows

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 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.

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.

• 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
• FDA and USP Class VI compliant seals
• Rated for full vacuum to 300psig

The Uni-San Sight Glass can be applied to any standard Tri-Clamp connection to create a viewing window in to your process. It has a long and successful track record across a broad range of process markets, and through continuous improvement efforts it is now better than ever! In particular, part number and traceability information, pressure rating, and temperature rating are now listed directly on the part. The standard finish has also been upgraded to an electropolish finish to meet bioprocess engineering standards.

Have you ever needed to shine a light in to a viewing port to get a clear view of your process? If so, did the reflection / glare or properties of the light lead to non-optimal or inconsistent results? Does this lighting process complicate your standard operating procedure? For anyone looking to light up a sight glass viewing window, we have the perfect product for you. Contact us today to learn more about the Uni-San Illuminator.
