Note : The sizes of 500 to 2600 mm (20 to 104 in.) are not
attached CE marking of PED.
*1: PS: Maximum allowable pressure for Flowtube
DN: Nominal size
*2: For details, see “Table 6 covered by ANNEX II of EC
Directive on Pressure Equipment Directive 97/23/EC.”
*3: AXF002G/C to AXF025G/W/C, AXF015H and AXF025H
are outside the scope of CE marking of PED.
(2) Installation
WARNING
• Tighten the bolts of the piping joints according
to the prescribed torque values.
• Take measures to protect the flowmeters from
forces caused by vibration channeled through
the piping.
(3) Operation
WARNING
• The instrument should be operated with the
temperature and pressure of the fluid under
normal operating conditions.
• The ambient temperature should be that of
normal operating conditions.
• Take measures to prevent excessive pressure
such as water hammer, etc. To avoid water
hammer prevent the pressure from exceeding
the PS (maximum allowable pressure) by
setting the system’s safety valves, etc. appropriately.
• Should external fire occur, take safety measures
at the device itself or system-wide
prevent it having an effect on the flowmeters.
• Avoid using fluids exceeding the corrosion
proof limitations of the lining and electrodes.
• Take measures not to abrade the metal pipe,
and avoid abrading the lining by using fluids
such as slurry and sand are contained.
