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

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

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.
