Seojin's Level & Flow Products

Fluid passing around a Pitot tube generates a pressure
difference between the front and rear of the tube that is
proportional to the velocity of the flow.
The holes placed on the front and rear of the tube are used
to sense the difference, which is needed to calculate the
flow rate.
Multiple sets of pressure sensing holes give a distinct
advantage in automatically averaging the non-uniform flow
profile across pipe.

The 12∼24 pressure sensing holes placed widely across
the entire cross-sectional area of the pipe responds
correctly to any velocity distribution and naturally
accommodate Reynolds Number Effect, and produce
differential pressures that represent highly accurate
average velocity.

Orifice Plates have a disadvantage of permitting a greater
pressure loss than other throttle elements (Flow nozzle,
Ventri tubes, etc.) do. but are most popularly used because
of their simpler shape, easier manufacture ability, lower
cost and higher reliability.
The types of orifice plates include concentric orifice plate,
eccentric orifice plate, segmental orifice plate, quarter-circle
orifice plate and square orifice plate.

The Cone is a differential head flow-meter consisting of a
circular cone placed in the center of a pipe section and
two pressure taps.
The upstream pressure tap is placed at a point where flow
is undisturbed by the cone, and the downstream tap at the
end of the cone facing downstream.
The liquid or gas flows through the annular gap formed
between the pipe wall and the cone, inducing a differential
head that is proportional to the flow rate.
