Where turbine flow meters are used
Turbine flowmeters will continue to have an
important role in the market for a variety of applications such as measuring
steady, clean, mid to high-speed flow of low viscosity fluids. Thanks to their
simplicity and solution related customizable capacity, turbine flowmeters prove
relevant despite new-technology flowmeters.
Turbine meters are a better cost-effective
option when dealing with larger pipe sizes. This is the case for ultrasonic,
Coriolis and especially for DP flowmeters, as many DP meters can be replaced by
one turbine meter. Turbine meters’ users are more likely to stay within their
already adapted technology.
Mechanical based turbine meters sales are
on the decline, favoring electronic-based multipath ultrasonic meters thanks to
their lower maintenance needs and less intrusive design. Their disadvantage
lies in their higher cost per unit and their high calibration costs. But,
because of their uncertain accuracy and performance, multipath ultrasonic
meters are losing ground to turbine meters.
Technology improved in Turbine flow meter
Turbine flow sensor’ moving parts are now
more reliable thanks to the technological breakthroughs. With the use of more
durable metals -such as synthetic sapphire- when making ball bearings, turbine flow
have increased the lifespan of their product. This removes
the edge new technology meters had over durability.
Some flow meter manufacturers have started
to promote things such as the “Dual Rotor Design” among other product
enhancements. The implementation of the dual rotor design gives the smaller
line of turbine flow meter sensor an increase in their operating range. Thanks
to this improvement, the two rotors now turn in the opposite direction making
the first rotor act as a flow conditioner redirecting flow to the second rotor.
Since they are hydraulically connected, the rotors will continue to turn even
in very low flow rates. This enhances the turbine flowmeters’ sustainability in
low flow conditions.
Low price cost of Turbine flow meter
Both electromagnetic flow meters and
ultrasonic meters are displacing -some, not all- turbine meters over their
utility measurement. Nevertheless, turbine flow meters retain a wide market
margin thanks to their price advantage over ultrasonic and mag meters. This is
why turbine meters will continue to have a larger market share in the industrial gas flow measurement
Wide applications of turbine flow meter
Turbine meters for oil applications are
used for hydrocarbon truck loading and unloading. Aviation applications also
make use of turbine meters. In this market, turbine meters compete with
Coriolis flowmeters and positive displacement meters. The Coriolis mass
flowmeter has been favored over turbine meters in these distribution
applications. Turbine meters are also employed in chemical plants and
refineries for in-plant clean liquid or gas flow rate measurement.
