Ultra™ 6C Liquid Ultrasonic Flowmeter

Brand: TechnipFMC
Request a Quote
The Smith Meter® Ultra 6c liquid flowmeter is an eight-path ultrasonic meter for custody transfer measurement of petroleum products.

The multiple measurement paths accurately resolve difficult flow profiles while maintaining linearity and repeatability over the widest range of conditions.

Crossing measurement paths cancel the velocity effects of fluid swirl providing the capability to handle compact installations with only 5D of upstream straight run.

As a result, the Ultra 8c exceeds the most demanding performance specifications on light to heavy petroleum products without the need for flow conditioning.

Principle of Operation

The Ultra 6c calculates flow rate by measuring the transit time of ultrasonic sound signals traveling back and forth across the flowing fluid.

The signal transmission and detection is achieved using piezoelectric transducers located on either side of the measurement path.

Flow velocity is calculated from the transit times and these velocities integrated to the total volumetric flow rate through the meter.

The Ultra 8c transducers are non-intrusive and flush mounted ensuring low maintenance requirements and no obstructions to full bore passage through the pipe.

The transducer element is fully encapsulated in a removable well, allowing it to be serviced with the meter under pressure.
Features
  • Custody transfer accuracy - +/-0.12 percent (%) linearity over 15:1 normal flow range and meets International Organization of Legal Metrology (OIML) R117 and American Petroleum Institute (API) requirements for custody transfer
  • Cancellation of swirl - Eight transducer paths precisely measure swirl and cancel any resulting transverse velocities for highly accurate performance in installations without flow conditioning
  • Heavy, high viscosity fluids at low Reynolds number - Eight measurement paths and dynamic profile compensation allow extremely linear performance from laminar to turbulent flow systems
  • 5D upstream straight run - Cancellation of swirl allows installations with 5D upstream straight run with no flow conditioning
  • Low frequency transducer option- Powerful signals penetrate the heaviest fluids maintaining measurement integrity and preventing signal loss on high viscosity and contaminated fluids or during cold flow startup conditions
  • Proving performance- High speed signal processing allows the Ultra 8c to exceed API requirements, proving in fewer runs and smaller prove volumes
