● Thermal insulation of integral
owmeter and remote sensor
When applying thermal insulation to a pipe
carrying high-temperature uid, do not wrap the
insulating material around the bracket (VY015 to
VY100) or the nozzle (VY150 to VY400).

● Flushing (cleaning) the pipe
If there is a possibility of scaling or sludge
(boiling scale, mud) inside newly installed or
repaired piping, ush the piping before operation.
When performing ushing, use bypass piping
to avoid damaging the owmeter. If there is no
bypass piping, install a short pipe in place of the
owmeter when performing ushing.
■ Mounting Precautions
Be sure to observe the following items so that
the performance of the vortex owmeter is fully
demonstrated.
(1) Gas or Steam Measuring Precautions
Ensure that accurate measurement can be
performed with the piping line lled with the uid
that ows through.
● Piping to Prevent Liquid Traps
Mount the vortex owmeter in a vertical pipeline
to avoid liquid traps. When the vortex owmeter is
installed horizontally, raise the part of the piping line
in which the vortex owmeter is installed.

(2) Liquid Measurement Precautions
The owrate cannot be measured accurately if
the piping line is not lled with uid. When piping,
observe the following precautions.
● Maintaining a Filled Pipe State
Make the uid ow against gravity upwards from
below. When the uid is owing with gravity, lift
the down-stream pipe length above the vortex
owmeter installation level to maintain a lled pipe
state at all times.
