Product Description

This new custody transfer meter offers exceptional linearity throughout the flow range to minimize lost and unaccounted for product. Next-generation electronics enhance meter operation and the full bore design ensures highly accurate low-flow measurement.

Specifications

Linearity
±0.15% of measured value over a 1.2 to 12.2 m/s (4 to 40 ft/s) range; ±0.20% of measured value over a 0.6 to 12.2 m/s (2 to 40 ft/s) range (optional)
Uncertainty of Meter Factor
>±0.027% (API MPMS, Chapter 5, Section 8, Table B-1)
Velocity
0.6 to 12.2 m/s (2 to 40 ft/s) with an extended range of 0.3 to 14.6 m/s (1 to 48 ft/s)
Operating Temperature Range
Transducers: -50°C to +100°C (-58°F to +212°F) or optional -50°C to +150°C (-58°F to +302°F)
Electronics: -40 to +60°C (-40 to +140°F)
Operating Pressure Range
0 to 155 Bar (0 to 2250 psig)
Materials
Carbon steel and stainless steel
Calibration
Conducted in Emerson’s ISO 17025 certified flow calibration laboratory

Features

  • Minimize measurement uncertainty and downtime with advanced diagnostics that pinpoint process upsets
  • Identify upstream blockages and abnormal flow profiles in real time using advanced MeterLink™ Software
