Basic sizing and selection
Selection
With so many choices, it is important to make the correct
selection of meter.
Historically, choices were limited by
!! Performance
!! Availability
Today a wider choice exists. This allows the user to focus on
what is best for each individual application. This can be
determined by a number of factors
!! Accuracy
!! Pressure Drop
!! Velocity
!! Design conditions
!! Material compatibility
Coriolis meter – tube designs
A comparison
Description
Twin tube
Tube Profile
Notes
!!U - Design
Original (first) design, remains in common use
!!V - Design
Evolution of U which allows self-drainage
Triangle - Design
Evolution of U providing high signal amplitude
$ - Design
Traditional design, often requires mechanical damping
!!S and Z tube
Good signal, can be pressure sensitive

A comparison
Description
Notes
Tube Profile
Single bent tube
!!Single bent tube designs exist in many of the same profiles as twin bent
tubes
!! For single S and Z meters drive and sensor measurement are
referenced from a rigid support structure
!!used for low flow meters
Twin straight
tube
!!Twin straight tube meters provide a similar amplification to the twin bent tube
!!designs
!!With advantages of low pressure drop and secondary containment
!!And ease of installation
Single straight
tube
!!Single straight tube meters offer the lowest pressure drop
!!Measurement is referenced to a rigid structure,
!!Also provide secondary containment and ease of installation
!!Ideal for abrasive or high viscous applications
Dual Bent tube
Well established design
!! Since early 1980’s
!! “established” design
No internal reference structure
!! Tubes vibrate with respect to
each other
!! Increases signal
Low internal stresses
!! Bends allow natural expansion of
tubes at higher temperatures

OPTIMASS Installation
!! Customer: OGSL BP Clair
!! 2 x OPTIMASS 2000 S250 in
an oil metering skid
!! Material Super Duplex
European sourced
!! Converters with SS housing
!! Elbow directly at the meter
inlet
!! Modbus electronics
!! Flow up to 438 t/h

Application
Abrasive fluids
Drilling Mud (Oil in Mud Measurement)
!! KROHNE have now completed a few projects
using the OPTIMASS 2000 for Oil in Mud
recovery processing
!! The flow splitter helps control the flow of the
mud reducing erosion.
!! The velocity flow rate through the meter is very
low (2m/s).
!! Therefore to eliminate dropout from suspension
the meter is mounted vertically.

also some horizontal installations.
!! This is a 4" piece of rubber that passed through
an S250.... Needless to say the customer (BP
USA) was impressed...
