Accurate steam measurement: From start up to full Operation.
Introduction
Steam has often been described as the ‘lifeblood’ of industry.
It is the medium by which heat from a boiler is converted into
an easily transportable form that can provide diverse services
from office heating to the mechanical energy that drives turbine
generators. Steam is still one of the most popular methods of
providing an energy source to a process and its associated
operations.

The Challenges
Most boiler systems are scalable to the plant’s needs, meaning
steam generation can be ramped up or down depending on the
need from the facility. This can range from low flows during start
up, to higher flows during full operation and back down to low
flows during downtimes of maintenance. It is important however
that accurate measurement of steam is essential in controlling
boiler efficiency and safety. The more accurate and reliable
measurements that are made, the more informed decisions can
be taken that affect costs and product quality.

The orifice flow meter is not suitable for low-flow measurement,
and can develop zero drift and span drift when the temperature/
pressure conditions fluctuate beyond the design specifications.
In order to measure larger turn downs with a orifice, the plates
must be changed periodically and the pressure transmitters
re-calibrated and spanned.
Vortex meters are known to be superior devices for steam flow
measurement due to their inherent linear measurement, large
turndown, low pressure drop and high accuracy. It is often thought
that it is no problem to install a line size meter to capture a wide
range
of flows but

While formerly two to three different types of orifice plates had
to be changed to adapt to fluctuations in the line flow rate, this is
no longer necessary with the digital YEWFLO reduced bore type.
This model reduces installation cost and expands the range of
applications available to end user.
The flow meter is available with a single reduction or a double
reduction in bore size, while still keeping the same face to face
dimension of a standard full bore vortex. This makes installations
on new projects simplified with no need for additional reducers

of Yokogawa’s

meter:
• Minimum measurable flow up to five times lower than conventional vortex flow meter.
• Integrated construction with reducers built into the flow meter
body.
• The same face-to-face dimensions ease the task of installing
other sizes or types of digitalYEWFLO flow meters.
• No need for costly piping modifications such as reducers/
expanders or short pipes to achieve the required straight pipe
length.
• Increases the space for installation of additional instrumentation
Yokogawa vortex flowmeters are also well suited to high
temperature applications, and the quality of flow management
can be improved even further through the use of anti-vibrating
