ANSI 600 Sight Flows

ANSI 600# High Pressure Sight Flow Indicators

These Sight Flow Indicators meet tough ANSI standards for 300# requirements. Made from single-piece, cast-construction bodies, these SFIs are available with all six styles of Penberthy indication.

 

Plain Sight Flow Indicator

A plain sight flow indicator can be used in a liquid application where there is a visual contrast between liquid presence and absence. Contrast in the form of color, tint, hue, clarity, or turbulence indicates variation in flow. Any orientation of flow can be observed.

Plain Flanged Sight Flow Indicator..................SH-F



Flapper Sight Flow Indicator

A flapper sight flow indicator can be used in a liquid application where there is a great enough liquid mass impact to lift the weight of the flapper. A hinged flapper indicates variation in flow by its position. Transparent or slightly opaque fluids can be monitored. Horizontal and vertically upward flow can be observed.

Flanged SFI (Flapper).............SHF-F


Rotator Sight Flow Indicator

A rotator sight flow indicator can be used in a fluid application where there is a great enough liquid mass impact to spin the Teflon® rotator paddle wheels. A spinning motion indicates variation in flow, ideal for darker color solutions where color contrast is better, translucent liquids and clear solutions. Any orientation of flow can be observed.

Drip Tube Sight Flow Indicator

A drip tube sight flow indicator can be used in a fluid application where there is formation of liquid droplets. Condensation collecting on the tube indicates variation in flow. Distillation and similar processes with intermittent flow can be monitored. Horizontal or vertically downward flow can be observed.

Gaseous Sight Flow Indicator

The Gaseous Sight Flow Indicator is the answer to detecting low velocity fluid streams. A Gaseous Sight Flow Indicator can be used in a fluid application where there is an air equivalent mass impact at a velocity of 2 feet per second or greater. Fluid medium can be either dry or wet gas.

A lightweight composite of Fluon®, Teflon®, and glass provides an excellent material for the gaseous indication flapper. The material has excellent wear resistance, heat resistance, and anti-friction characteristics. The indicator material meets MIL-1-18746A specifications.

The composite material is dimensionally stable under heat and pressure and is resistant to cut-through and cold-flow. The indicator material is adequate for temperatures ranging from -400° F (-205° C) to 500° F (260° C). Steam may be the fluid medium in Gaseous Sight Flow Indicators with mica shields up to the design temperature of 500° F (260°). The gaseous indication flapper material has excellent resistance to all solvents, acids, flues, weathering, moisture, and chemicals except fluorine at high temperatures and certain complex organic halogens, like Freon.

The indicator is similar in operation to a hinged flapper. When the fluid meets the fringed indicator sheet, the material flutters, indicating flow. Transparent or slightly opaque fluids can be monitored effectively. The Gaseous Sight Flow Indicator is most effective in horizontal applications but can be used in vertically upward flow applications.

The Gaseous Sight Flow Indicator is ideal for industries such as:

  • Petroleum/light fuel/solvents

  • Laboratory and industrial chemical process

  • HVAC (heating, venting, air conditioning)

  • Sinking/dewatering wellpoint

  • Flue gas

  • Sewage treatment (raw, sludge, treated, effluent)

The indicator can be used to indicate:

  • System gas leaks

  • Chemical reaction pressures exceeding that of atmospheric

  • Low velocity flow streams from natural gas wells

  • Presence of superheated steam (superheat temperature must not exceed 500° F (260° C).

Gaseous Sight Flow Indicators are available in most Penberthy sight flow indicator models. The Gaseous Sight Flow indicators are constructed similarly to the flapper model indicators. If a sight flow indicator is available with a flapper, it can be converted to a gaseous model. The Gaseous Sight Flow indicator models are designated in each product class by the final letter "G".

Ball Type Sight Flow Indicator

The Ball Type Sight Flow indicator is ideal in process applications where visualization of flow is at a premium. Typical applications include gaseous or clear liquid processes. Available in NPT and flanged connections, these indicators meet ANSI standards for 150#, 300# and 600# requirements. Ball Type indicators should be mounted in a vertically upward or horizontal flow orientation.

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.
