T-piece applications
Flow rate 0.5 to 3 m/s at main pipe wall
By increasing the insertion depth of the tines into the T-piece, the
flow velocity can be increased to 5 m/s for clean fluids. For slurry
applications, the maximum flow velocity should be no greater
than 4 m/s.
Viscosity • For the 2 in (51 mm) (DN50) T-piece, viscosity limit is 100 cP
(200 cP in some cases).
• For the 3 in (76 mm) ( (DN80) T-piece, the viscosity limit is
1000 cP.
Temperature -58 °F (-50.0 °C) to 392 °F (200.0 °C)
Main flow pipe size Minimum diameter, 2 in (51 mm)
Advantages • Simple installation in large bore pipes
• Ideal for clean fluids and non-waxing oils
• 3 in (76 mm) T-Piece installation ideal for high percentage
slurry applications
• Suitable for line density measurement and simple referrals
Recommendations Do not use with:
• Low or unstable flow rates
• Where step changes in viscosity can occur
• For small bore pipes
• Where temperature effects are significant
Flow-through chamber applications
Flow rate

section (1.5 - 80 gal/min)
Viscosity • For the 2 in (51 mm) (DN50) Flow Chamber, viscosity limit is
100 cP (200 cP in some cases).
• For the 3 in (76 mm) (DN80) Flow Chamber, the viscosity
limit is 1000 cP.
Temperature -58 °F (-50.0 °C) to 392 °F (200.0 °C)
Main flow pipe size Suitable for all sizes, if mounted in a bypass (slipstream)
configuration
