(2) Installation

WARNING

• Tighten the bolts of the piping joints

according to the prescribed torque values.

• Takemeasurestoprotecttheowmeters

from forces caused by vibration channeled

through the piping.

(3) Operation

WARNING

• The instrument should be operated with the

temperatureandpressureoftheuid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reoccur,takesafety

measures at the device itself or system-wide

preventithavinganeffectontheowmeters.

• Avoidusinguids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uids

such as slurry and sand are contained.
