ANSI 150# Sight Flow Indicators

For common process flow stream pressures, use the industry standard.
Available in NPT threaded-end and flanged designs, these Sight Flow Indicators meet most standard installation requirements.  Made from single-piece, cast-construction bodies, these SFI's are available with all five styles of Penberthy indication.  Ball type indicators should be mounted in a vertically upward or horizontal flow orientation.

High Pressure Sight Flow Indicator Applications
.
Naturally occurring high pressure wells (natural gas, petroleum, geothermal steam) and long distance pumping (transportation) of liquids and gases require High Pressure Sight Flow Indicators to observe fluid dynamics.

Chemical processes often require that fluids be in their liquid state.  To achieve this the chemical must remain under pressure at all times so that it can be transported using high pressure pumps.  Observing the flow of chemicals such as Argon, Hydrogen, Nitrogen, Oxygen, Carbon Monoxide, Propane, Ethyl Methyl Ether, Butane, Isobutane, Pentane in their liquid state requires High Pressure Sight Flow Indicators.
