*** SE115D/E and SE202D/E are not attached CE
mark of PED because they do not come under CE
marking of PED.
(2) Installation
WARNING
• Please tighten the bolts for piping-joint
according to the prescribed torque values.
• Please take measure to protect the flowmeters
from forces caused by vibration through piping.
(3) Operation
WARNING
• The temperature and pressure of fluid should
be applied under the normal operating
condition.
• The ambient temperature should be applied
under the normal operating condition.
• Please pay attention to prevent the excessive
pressure like water hammer, etc. When water
hammer is to be occurred, please take
measures to prevent the pressure from
exceeding PS(maximum allowable pressure) by
setting the safety valve, etc. at the system and
the like.
• When external fire is to be occurred, please
take safety measures at the device or system
not to influence the flowmeters.
• Please avoid the fluid exceeding the corrosion
proof of lining and electrode.
• Please pay attention not to be abrade the
metal pipe, when the fluid to abrade the lining
such as slurry and sand are contained.
