(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.
