SC-250 Pressure and Temperature Limitations vs Materials

Below are details of the maximum Pressure and Temperature limits for the SC-250.

1. The pressure limits for the standard version are:
With SS-316 flow tube or SS-316 flow tube with PVC or PTFE Liner:
PN-40 (40 Bar) for sizes DN-15 to DN-65
PN-16 (16 Bar) for sizes DN-65 to DN-125
PN-10 (10 Bar) for size DN-150.

With All PVC, PP, PTFE and PVDF flow tubes:
PN-16 (16 Bar) for sizes DN-15 to DN-125
PN-10 (10 Bar) for size DN-150.

The float material does not change the pressure rating.

If the pressure limits for the standard versions are too low then we can offer special versions with higher pressure ratings but the price is also higher. We can offer with many different pressure ratings up to 400 Bar. The higher the pressure rating the higher is the price. If a pressure rating higher than the standard version is required then ask for a special quotation.

2. Below is a summary of temperature limits for the SC-250.

SC-250 with PVC materials (float and/or body): --> 0 to 50 Deg C
Above 45 Deg C the pressure rating is reduced, check pressure rating if over 45 Deg C.

SC-250 with SS and PTFE materials and no transmitter or alarms: --> -20 to 150 Deg C
Limit is due to PTFE

SC-250 with only SS materials and no transmitter or alarms: --> -20 to 200 Deg C
For higher or lower temperatures, use the Thermal Separator option SC/HT

SC-250 with SS and PTFE materials and with transmitter or alarms: --> -10 to 90 Deg C
For higher or lower temperatures, use the Thermal Separator option SC/HT but max 150 Deg C due to PTFE.

SC-250 with only SS materials and with transmitter or alarms: --> -10 to 90 Deg C
For higher or lower temperatures, use the Thermal Separator option SC/HT

The Thermal Separator option SC/HT is suitable for temperatures from -50 to 250 Deg C.
The SC-250 can be offered for temperatures up to 400 Deg C or down to -180 Deg C, for temperatures above 250 Deg C or below -50 Deg C ask for a special quotation.
