－30 to ＋300℃
Nominal size 200～300mm with flange material SFVC2A…0 to 300℃
(Temp. limitation depends on the flange material used.)
Standard type :－30 to ＋300℃
High temp. type : －30 to ＋460℃
However, min. temp. for nom.
size, 200 to 300mm is specified
as 0°due to limitation in
material component.
Max. operating pressure Depends on flange rating (Design pressure: 5.00MPa).
Accuracy
Select one from the following two ranges according to the given operating conditions:
1: ±1％ of indicated reading or better 2: ±1％ of full scale or better ＊4
Repeatability ±0.2％ or better

SCS14A
Nom. size 10mm･･･SUS316
SUS316 or SCS14A
(Nom. size 200 to 300mm…Flange material is SUS316 or SFVC2A.)
Bluff body
(delta or dia. shaped)
SUS316 or SCS14A
Adapter SUS304 or SCS13A
Installation
No restrictions to cause loss of accuracy on physical orientation
Maintainability and waterproof work for cable entry should be taken into consideration.
Finish (measuring pipe)
Nominal sizes 10 to 300mm: Remains unfinished (because of stainless steel material)
Nominal sizes 200 to 300mm: Phthalate resin finished Munsell 2.5G8/2 (SFVC2A only)
(＊1): If different from piping of standard nominal wall thickness, consult the factory. (＊2): 10mm is dedicated for liquid measurement only.
(＊3): With nominal size 200 to 300mm. and flange material SFVC2A, the allowable operating temperature covers a range above 0℃ due to
temperature limitations by flange material.
(＊4): Accuracy of 10mm in nom. size is ±2% or better with respect to the max. rated flowrate.
