Flow meters are utilized to measure totalized volumetric flow rates for
fluids. There are several types of industrial flow meters available on
the market, however, each of it has its own advantages and is
specialized in its own area of use. The positive displacement, for that
instance, is a mechanical meter best suited for non-corrosive, clean
mediums huarenblog. It is capable of measuring a wide range of fluids including those that contain high viscosities.
Define: Positive Displacement(PD)
These are colloquially also referred to as the workhorses in the flow
measurement applications. It is a device that measures the flow rate of a
fluid by allowing it move through the system in increments. They are
highly capable of performing multiple intricate and vital flow
measurements when implemented in industrial applications single curtain track bracket.
Although, Positive displacement meters face a lot of competition from
the advancing new-technology meters available on the market, they remain
an effective solution for certain specific applications. Positive
displacement (PD) are widely and mainly applied in billing applications
for both, gas and liquids. They help to determine the amount of gas that
is being used in various commercial offices, buildings, residences, and
other massive industrial plants.
Principle of Working
This is the only flow measurement technology that directly measures the
volume of the liquid or fluid passing through the flow meter chain saw.
The action of fluid transfer is achieved by placing an oscillating,
nutating, or rotating object in the fluid path so that it measures the
exact quantity of the displacing fluid. One of the most popular nutating
disc type flow meters in the industry technology is the Positive
Displacement Neptune semi precious gemstone beads .
These devices repeatedly entrap the fluid in the system in order to
measure its overall flow. The entrapment is typically achieved by using
rotating parts that constitute the moving seals between one another
and/or the flow meter body. The rotation in the system can either be
detected mechanically or by detecting the overall movement of a rotating
part. However, it is naturally understood that if more fluid flows
through the system, the rotating parts turn faster. Furthermore, a
transmitter present in the meter processes the signal to determine the
flow of the fluid.
Varying Designs in a Positive Displacement Flow Meter
Many PD meters are designed differently, wherein, the rotating parts
consists of tight tolerances so that the seals can prevent the fluid
from entering the meter before it is measured. Another design consists
of bearings that help to support the rotating parts blogmonster.
Additionally, some displacement meters have output pulses that are
often used by a secondary electronic instrument in order to determine
the flow rate, whereas, some other meters have mechanical registers that
display the overall flow on a local display
