Product Description

Flow Meters deliver exceptional custody transfer accuracy and reliability by combining the power and performance of a field proven Rosemount four-path chordal, British Gas-design meter (OIML R137 1 and 2 Accuracy Class 0.5) with a second reflective check meter in one body.

Specifications

Accuracy
4-Path Meter: ±0.05% of reading relative over entire calibration range
2-Path Meter: ±0.2% of reading with calibration (±1.5% of actual vol without calibration)
Repeatability
4-Path Meter: ± 0.05% of reading for 5 to 100 ft/s (1.5 to 30.5 m/s)
2-Path Meter: ± 0.1% of reading for 5 to 100 ft/s (1.5 to 30.5 m/s)
Velocity
Rated up to 100 fps (30 m/s) with over-range performance exceeding 125 fps (38 m/s) on some sizes
Operating Temperature Range
T-21 Transducers: -20°C to +100°C (-4°F to +212°F)
T-22 Transducers: -50°C to +100°C (-58°F to +212°F)
Operating Pressure Range
T-21/T-22 Transducers: 689 to 27,579 kPag (100 to 4,000 psig)
T-21/T-22 Transducers: 345 kPag (50 psig) minimum operating pressure available with reduced Qmax (see product datasheet)
Materials
Carbon steel and stainless steel

Features

  • Detect even trace liquid/debris along the pipe bottom in real time with highly sensitive, vertical diagnostic path
  • Patented transducer synchronization method ensures the flow meter’s electronics provide the highest sampling rates possible without cross-interference.
  • Avoid common mode errors with chordal and reflective paths that work in unison
  • Reduce measurement uncertainty with process alerts for wall buildup, liquids, blockage and deviating gas quality
  • Speed issue resolution with 3D view of the flow profile that indicates swirl, crossflow, asymmetry and turbulence
  • Reduce manual errors with automatic calculations of AGA 8 Compressibility and AGA 10 Speed of Sound
  • Increase I/O with new Type 4 CPU Module with up to six frequency or digital outputs
  • Increase I/O with new Type 4 CPU Module with up to six frequency or digital outputs
