4.3 Replacing float
Devices with measuring ring
For devices with standard measuring ranges
starting from 5 - 50 l/h (gases: 0.15 – 1.5 m³/h)
the replacement of the float can be provided by the
customer:
● Remove the device from the piping.
● Fix the device ideally in a horizontal position,
ensuring that the fitting will not be damaged.
● Prevent the float
from torsion by fixing the
upper guide bracket
using a suitable tool.
● Remove the self-locking nut
which fixes the
lower guide bracket
and take the guide
bracket out of the fitting.
● Take the float upwards out of the measuring
unit.
● Insert the new float into the fitting from the top.
At the same time carefully guide the bottom
end of the float through the measuring ring.
● Slip the lower guide bracket through the thread at the bottom end of the float and fix it with
the self-locking nut.
● Install the device back into the piping.
Important!
Avoid damaging both float and measuring ring
.
Important!
After float replacement a recalibration of the flowmeter is highly
recommended, otherwise the measurement accuracy cannot be ensured.
Devices with cone
● Replacing floats for devices with cone (standard measuring ranges up to 5 - 50 l/h (gases:
0.15 – 1.5 m³/h) cannot be done by the customer. The device has to be returned to the
manufacturer. For details please refer to chapter “6.4 Returning the device to the
