General Description
The Sentry® Level-Lenz sight level indicator oers a cost eective method for
process operators to conrm the level of liquid without disrupting the process
or ow. Sight level indicators provide a safe way for operators to visually monitor
liquid levels in closed loop sampling processes.
Sentry Level-Lenz sight level indicators are manufactured of quality materials and
safety tested to 150% of the rated pressure to assure long, dependable service at
economical prices. The Level-Lenz has threaded process connections, two viewing
windows, and a body of 316 stainless steel. The Level-Lenz has a double window,
one on the front and one on the side. The operator can ash light through the side
window to enhance visibility. The level indicator can be used for hydrocarbon and
water-based liquids.
