Model RAGN
Glass Rotameter

Installation:

All packaging material must be removed. The transportation lock for the
float must be removed.
The piping shall be flushed before installing the flowmeter. Piping must
be dried for gas applications. Rotameters must be installed vertically. The
flow direction is from bottom to top. Prevent the device from mechanical
stress and vibration by aligning and supporting the piping. Avoid large
volumes of gas downstream and upstream of the device, this can cause
vibration due to compression. Install the On/Off valve downstream in order
to avoid damage when opening the valve. In case of gas applications,
increase the flow pressure slowly. Avoid pressure surges and temperature
shocks to the flowmeter at any time. Refer to the pressure and tempera-
ture limits of the device. For flowmeters with limit switches please see
Instruction Manual IM 01R01B10-00E-E.
Further installation hints can be found in VDI/VDE 3513 sheet 3.

Commissioning:

When functioning properly, the float moves freely in the flow. With floats
with notches this can be easily seen by their rotation. If the float does not
move, please check the installation.
The flow rate can be read directly from the scale on the tube. Refer to the
scale mark to which the float adjusts its top edge when reading.

Maintenance:

With common applications and normal operating conditions the device is
maintenance free. In case of soiling we recommend to clean the measur-
ing tube by using a bottle brush and soap water. Make sure not to scratch
the measuring tube. If float or measuring tube show signs of wear and
tear, we recommend replacing them.

Warranty:

YOKOGAWA gives no warranty for the improper use of glass flow meters.
Due to the uncontrollably of the material YOKOGAWA cannot guarantee that the
material is fracture-proof.
