Description
The patented Flow Technology Decathlon Series of industrial in-line flowmeters
is ideal for a wide variety of liquid flow applications. These applications include,
but are not limited to, paints, resins, petrochemicals, lubricants, fuels, polyurethanes
and adhesives. These flowmeters are both highly accurate and easily adaptable
to most industrial applications.

 |
• 1/8" to 2" line sizes
• Reference accuracy ±0.05% of rate
• Only two moving parts
• Bearingless design
• Easy to install and maintain
• Handles viscosities up to 1,000,000 cP+
• Up to 1000 psig operating pressure
• Operating temperatures up to 400° F (204° C)
• Wide range of applications
• Non-intrusive sensor
• Up to 1000:1 turndown
• Various process connection types available
• Handles pulsating flow streams
Principle of Operation
Flow Technology positive displacement flowmeters use two rotating impellers driven
by the flowing liquid. Magnets
imbedded in the impellers activate a non-intrusive
sensor which generates a pulsed output signal.
Each pulse represents
a known volume of liquid that is captured in
between the lobes of the impellers. A K-factor
converts the pulses into
engineering units for remote data collection
and digital display.
Specifications
Operating Temperature
Up to 400° F (204° C) based on impeller materials
Operating Pressure
Standard 250 psig max. (1724 kPa)
Optional Up to 1000 psig (6895 kPa)
Turndown Ratio
(model's max. rated flow ÷ its minimum
flow rate)
Low viscosity fluids 10:1 standard
