Kyoritsu Gokin conducts various fluid tests
and experiments. Typical test apparatuses include
the PDPA system for the measurement of particle
size and flow velocity, the particle size measurement
system incorporating image analysis, the flow
distribution measurement system, and the impact
force distribution tester.Test results are
utilized as fundamental data to improve the
existing lines and to establish new technologies.
Using these test apparatuses, we conduct tests
and provide test results to meet your specific
needs. |

 This
system is a particle analyzer making use of the
phase doppler principle of the laser doppler system
to measure the velocity and size of a particle
simultaneously. The phase doppler principle is
as follows. A lens placed on the transmitter allows
two divided laser beams to cross each other. As
particles pass the intersection, scattered rays
form fringes. The receiver detects these fringes.
PDPA (using the phase doppler method) measures
the particle size of a continuous spray without
interference with the spray. It is capable of sampling
many particles instantaneously and has become dominant
in particle size analysis.
PDPA is suitable for the measurement of relatively
small particles. |

 This
system determines average particle size by measurements
incorporating image analysis using a flash and
CCD camera as basic devices. It measures particle
size regardless of the shape of particles (spherical
or a spherical) and type (clear or opaque) .
This system is suitable for measuring relatively
large particles. |

This system measures the distribution of spray flow
density using an acrylic container grid, on which
a liquid is sprayed, and the amounts of deposits
are measured. It is also capable of measurement
results in a flow distribution graph. |

This system determines the impact force distribution
of a spray by running a pressure sensor underneath
the spray. It is also capable of producing
measurement results in an impact force distribution
graph. |

A high-precision sensor with sensing
width (B) travels at a fixed rate to
record impact forces across the spray
width. |
| |
 |
| |
|
Obtained data are used to assess the
distribution shape, impinging force,
and spray width. |

A sensor with a pressure-sensing surface
(D) in diameter travels at a fixed
rate to record impact forces across
the spray thickness. |
| |
|
| |
|
Obtained data are used to assess the
maximum impact force per unit area
and spray thickness. |
