CHEM Flowtronics sight flow indicators, Model 100 and 101 standard in-line flanged sight flows incorporate all the features shown below and are available in 316 stainless steel (wetted parts) or carbon steel. Pipe line sizes are available up to 20 inches. Our Model 101 has face-to-face dimensions to match other manufacturers (specify when ordering.)

The Model 100-R and 101-R (rotor models) offer flow indication in hard-to-see applications. The rotors are manufactured of Teflon® and offer full paddle exposure across the drip tube for positive one-directional rotation.

The Model 100-F and 101-F (flapper models) provide the flow detection and, depending upon process, can show a variation in flow. These models are used for horizontal or upward flow.
