Sentry Flo-Lenz Sight Flow Indicator
- Part #
- Sentry Flo-Lenz
- Model #
- Flo-Lenz
The Sentry Flo-Lenz sight flow indicator allows operators to confirm that a sample stream is flowing as specified through a process, without disrupting the process or flow. Sight flow indicators provide a safe way for operators to visually monitor high pressure and/or high temperature closed-loop sampling processes. These sight flow indicators are safety tested to 150% of the rated pressure to assure safe, dependable service.
The Flo-Lenz sight flow indicator has threaded process connections, two viewing windows, and a body of 316 stainless steel. Through double windows, one on the front and one on the side, a Teflon ball is visible at a flow rate beginning at approximately 50 cc/min. The operator can flash light through the side window to watch the flow.
The Flo-Lenz sight flow indicator can be used for hydrocarbon and water-based liquids.
