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.


Features

• 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
Medium viscosity fluids 100:1 standard
High viscosity fluids Up to 1000:1

Repeatability
