Help with Sight Flow Indicators specifications:

Flow Indicator Style
   Flow Indicator Style:       
   Your choices are...         
   Plain       Plain sight flow indicators are window-only devices. There are no moving parts to indicate flow. The unit may be mounted in any direction, but the flow is bi-directional. Plain sight flow indicators are used to detect easily-visible fluids, or the absence of such fluids. These devices are also used to detect color clarity and fluid turbulence. 
   Flapper       Flappers are sight flow indicators with a flap that lifts when liquid flows. Devices may be mounted either horizontally or vertically, and have an upward flow. Typically, flappers are used with clear fluids. 
   Rotor       Sight flow indicators have a rotor that turns when liquid is flowing. Devices may be mounted in any direction, but right-to-left flow is standard. Rotor-style sight flow indicators are designed for clear, translucent, or dark fluids. 
   Drip Tube       Liquid drips into the indicator through a small opening in the end of the device. Units are designed for vertical applications, and only have downward flow. Drip tube sight flow indicators are recommended for applications with intermittent gravity or extremely low flow-rates. 
   Full View       Full-view sight flow indicators are cylindrical. The full indicator can be seen from all sides.  
   Armored       Armored sight flow indicators are also cylindrical, but have supports on either side. Liquid flow is viewable from only the front and back of the device. 
   Flapper Gaseous       Sight flow indicators have a flap that lifts when gas is flowing. Units may be mounted either horizontally or vertically, and have upward flow.

Connection Type
   Connection Type:       
   Your choices are...         
   Threaded       Devices have a pipe thread for connection to piping. 
   Flanged       Devices have flanges for connection to piping. 
   Butt Weld       Butt welds are a fluid piping connection option for sight flow indicators. A butt weld implies a precision welding technique - for example, orbital welding - was used to make a liquid-tight weldment, minimizing risk of contamination to the process liquid. Applications using this type of connection include pharmaceutical, chemical, and dairy. A butt weld may help a component meet sterility or FDA requirements in a sanitary liquid system.

Body Material
   Body Material:       
   Your choices are...         
   Brass       Brass offers good strength, excellent high-temperature ductility and reasonable cold ductility, good electrical conductivity, excellent corrosion resistance, good bearing properties, and low magnetic permeability. 
   Bronze       Bronze is a porous material that can be impregnated with oil, graphite or polytetrafluoroethylene (PTFE). Bronze is not suitable for heavily-loaded applications, but is useful where lubrication is inconvenient. 
   Iron - Ductile       Ductile iron retains cast iron's machinability and corrosion-resistance. It provides additional strength, toughness, and ductility. Although it’s chemical properties are similar to those of cast iron, ductile iron incorporates significant casting refinements, additional metallurgical processes, and superior quality control. 
   Steel - Carbon       High-carbon, hard-drawn steel is used when impact- and abrasion-resistance is required. 
   Steel - Stainless       Stainless steel is chemical and corrosion resistant, and can have relatively high-pressure ratings. 
   Other       Other unlisted, proprietary or specialized materials.

Features
   Sanitary?       Devices are rated for sanitary applications. 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
   Single Window?       The flow rate is viewable from only one side of the device. 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
   Double Window?       Double-window devices have one window in the front and one in the back. These sight flow indicators are best for observing a liquid's clarity or color. 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
   Dual Window (FM Approved)?       Dual windows are comprised of two glass discs held in position by a metallic housing, internal shims and gaskets. The double, tempered-glass window design provides added protection in applications where there is external mechanical impact or corrosion/erosion. FM Approval means that the indicator meets Factory Mutual (FM) system standards. 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
   Teflon Lined?       Devices are designed with Teflon® for transporting and viewing corrosive materials. Teflon is a registered trademark of DuPont.
