6.6 Pressure derating
The graphs below refer to the maximum pressure as a function of the temperature for the
flanges of the flowmeter (per specified flange material).
Please note that the specified values only refer to the flanges. The maximum value for the
flowmeter can futher be limited by the maximum value for other materials ( o.a. the liner )
For A = Carbonsteel A 105 & B = Stainless steel 316L
X/Y axes in all graphs ; X = Temperature in [°C] / Y = Pressure in [bar]
x/y axes in all graphs ; x = Temperature in [°F] / y = Pressure in [psi]
