Figure 2-6: Stay away from the process connections
WARNING!
Stay away from the process connections. If you stand on the process connections, you can cause
damage to the device and the installation.
DANGER!
Make sure that the outer surface temperature of the device is not more than 60
° C / 140 ° F. If the
surface temperature is more than 60
°
C / 140
°
F, use the device with precautions that agree with
Health and Safety rules and regulations.
WARNING!
Pressure Equipment Directive 97/23/EC data
• The process connections must be attached correctly to prevent mechanical stress. The axis
of the process connection must be parallel to and centred with the axis of the tank's process
connections. Tighten the process connections in agreement with the design code.
• The user must take necessary steps to protect the installed device from shock waves (water
hammer). A pressure limiting valve must protect the installation.
• The effective pressure of the installation (the maximum permitted by the pressure limiting
valve) must never be greater than the maximum permitted pressure, P
s
, marked on the
device nameplate.
• Make sure that the parts in contact with the fluid are compatible with the fluid and conform to
the ageing characteristics of the measurement environment and the fluid used. These have
either been recommended in the instructions or form the subject of a particular specification
in the contract.
• The external pressure, P
ext
, must be equal to atmospheric pressure, P
atmos
(P
ext
= P
atmos
).
• If stainless steel devices are more than 6 m / 20 ft high, we recommend more anchoring
points.
CAUTION!
Before you fill the tank, make sure that the column of rotating flaps is set to zero (the flaps are
all black). If not, the device may incorrectly indicate the level.
