Flow Sights for Food and Beverage
Made of FDA-listed materials for use with food and beverage, these sights have sanitary quick-clamp connections and an electropolished 316 stainless steel body for easy disassembly and cleaning. They meet USP (United States Pharmacopeia) Class IV standard for food applications. Sights let you visually confirm flow and inspect liquid color and clarity. Backlight the back window to increase the visibility of dark liquids.

Sanitary Electronic Insertion Flow Switches
Easy to clean and install, these flow switches are 3-A certified to meet sanitary design standards and insert into your line with a quick-clamp mounting adapter (sold separately). They have a smooth probe, and unlike flow switches that measure with a paddle or turbine, these don’t have moving parts for contaminants to get stuck in. Rated IP67 and IP69K, they withstand temporary submersion and high-temperature, high-pressure washdowns. The mounting adapter attaches to a quick-clamp tube tee or outlet (often called tri-clamp fittings) in your large-diameter tubing system using a gasket and clamp (not included), so you don't need to disassemble your line for inline installation. This mounting adapter is also easy to remove and clean.
They send digital signals to your programmable logic controller (PLC) to activate automated controls or alarms when they reach a set flow rate. To calculate the flow rate, they generate a small amount of heat, then measure the cooling effect your liquid or gas has on it. This makes them ideal in applications with fluctuating temperatures. Use the buttons on the display to adjust the set point and other settings. They’re accurate in any mounting orientation.
