(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.
