Relating Hooke’s Law to the Coriolis meter
Mass of the system comprises
!! Mass of the tube (m tube) - fixed
!! Mass of the fluid (m fluid) - variable
Mass of the fluid is calculated
!! Tube volume (v tube) - fixed
!! Fluid density (" fluid) - variable

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
Twin tube
Description Notes Tube Profile !!U - Design
!!V - Design Triangle - Design $ - Design
!!S and Z tube
Original (first) design, remains in common use
Evolution of U which allows self-drainage Evolution of U providing high signal amplitude Traditional design, often requires mechanical damping
Good signal, can be pressure sensitive

Tube Profile
Coriolis meter – tube designs A comparison
!!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
Twin straight tube
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
Description Notes
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
Coriolis meter – tube designs 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

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.
