ast month, we introduced the
dilemma that, even as the oil and
gas industry expands its use
of produced water during extraction
operations, it faces mounting
constraints on its use and disposal.
Thus, with a heightened importance
of accurate and reliable measurement
of produced water flow at every
stage, more companies are turning
to electromagnetic flowmeters,
commonly known as magmeters. Now,
we'll walk through some of the details
for and benefits of transitioning from
mechanical flowmeters to magmeters.
Not only do they offer higher
accuracy, more reliability, and ease of
maintenance, but they also open the
door for smart meter capabilities, as
we'll see below.

TRANSITION FROM
MECHANICAL FLOWMETERS
While mechanical flowmeters have
traditionally been a common choice
for measuring produced water, an
increasingly rapid transition towards
electromagnetic flowmeters is
occurring in new installations and
repair/replacement scenarios.
This transition is motivated
by vastly improved accuracy,
reliability, longevity, and easeof-maintenance.
Moreover,
electromagnetic flowmeters
offer additional capabilities such
as online diagnostics, and data
collection, making them a compelling
choice. Due to their accuracy and
reliability, they can also be used for
leak detection.

ACCURACY, RELIABILITY, AND
EASE-OF-MAINTENANCE
First and foremost, electromagnetic
flowmeters are completely electronic,
eliminating the need for any moving
parts. This makes them far more
robust and less prone to wear and
tear, thereby reducing the need
for frequent maintenance and
replacement. As a result, they have an
exceptionally long lifespan. Krohne
has magmeters that have been in
service for over twenty-five years,
continuing to provide accurate flow
measurement of produced water.
Second, electromagnetic
flowmeters offer better accuracy
compared to their mechanical
counterparts. Mechanical flowmeters
can be affected by the viscosity of
