KSF Sight Flow Indicators
All KSF Sight Flow Indicators employ dual glass for see-through visibility. The KSF Sight Flows are available in two series - ST and HT
The ST series is designed for standard temperatures and pressures while the HT series is designed for high pressure and temperature.
NO LEAK DESIGN
Kenco has been manufacturing products for 35 years. The KSF sight flow has many proven design features. The radial sealing method and bolt-on body design provides years of service with no torquing maintenance required.
It works so well it's guaranteed no leaks for three years under normal use!

- Temperature in excess of 500 º F possible with special high temperature seals. Consult factory.
THREE YEAR WARRANTY
All KSF Sight Flow Indicators are guaranteed free from defects in material and workmanship for three years from date of shipment.
If a KSF Sight Flow Indicator fails within the first three years, we will supply parts or replacement parts or replace the entire unit at no cost.
ANSI RATED
The cast body and the threaded of flanged connection meet ANSI standards. Flanged models conform to standard ANSI mounting dimensions; threaded models are provided with standard NPTF threads. All flanged units are supplied with 150 lbs. raised-face flange. The 2", 3", and 4" can be supplied with 300 lb. flanges.
Options:
KSF Sight Flow Indicators can be supplied with special gasket materials and glass shields. The standard materials of construction are carbon steel, ductile iron, 316 stainless and bronze. Hastelloy C 276 and alloy 20 can be supplied. Please consult the factory for pricing.
Sight Flow Indicator Options
|
PLAIN
Unit may be mounted in any direction and flow is bi-directional. Used to indicate easily visible fluids
or lack of same to detect color clarity of turbulence of fluids.
|
FLAPPER
Units may be mounted either horizontally or vertically with upward flow. These units are used with clear fluids.
|
|
ROTOR
Unit my be mounted in any direction. Right to left flow is standard. Specify if left to right flow is required. Rotor is highly visible. The units are designed for clear, translucent or dark fluids. Standard rotor material is Delrin. PTFE is available as an option.
|
DRIP TUBE
Units are designed for vertical application only with downward flow. They are recommended for intermittent gravity or extremely low flow rates.

COMPETITOR OVERALL LENGTHS
The KSF flanged sight flow indicators are available with overall lengths that equal Penberthy units. The KSF units are supplies in either stainless steel or carbon steel in 2", 3" or 4" 150 lbs. flanged ends. Both the standard pressure unit and the high pressure unit may be ordered in these lengths. To specify these lengths, change style designation from KSF to KPJ.
