*1: PS: Maximum allowable pressure for flow tube, DN:
Nominal diameter
*2: Table 6 covered by ANNEX II of Directive 2014/68/
EU
*3: Article 4, paragraph 3 of Directive 2014/68/EU
*4: Models classified as Category II cannot be used for
unstable gases in Group 1.
*5: VY150 with nickel alloy CW-12MW body material is
not compliant with PED.
(2) Installation
WARNING
• When installing on piping, firmly tighten the bolts
at the appropriate torque values.
• Take measures to protect the flowmeter from
force caused by vibration through piping.
(3) Operation
WARNING
• The temperature and pressure of the fluid
should be applied under normal operating
conditions.
• The ambient temperature should be applied
under normal operating conditions.
• Pay attention to prevent excessive pressure
such as water hammer. When water hammer
occurs, take measures such as installing a
safety valve on the system to prevent the
pressure from exceeding PS (maximum
allowable pressure).
• When an external fire occurs, take safety
measures at the device or system to prevent the
flowmeter from being affected.
• Pay attention to abrasion of metal pipes when
using abrasive fluids that contain slurry or sand
and the like.
