If the meter has been ordered with a heating jacket, it will be supplied with NPT, Ermeto or
flange connections.
Connecting / using the heating jacket
• Use reinforced flexible hoses to connect the heating jacket to the heat source.
• The heating jacket material is 316L but the heating medium is also in contact with the outer
cylinder, which might be a lower grade Stainless Steel.
• Suitable heating mediums are steam or hot oil. Avoid the use of heating mediums that can
cause crevice corrosion in Stainless Steel.
• Where liquid is being used, set up the pipe configuration so that air can be vented from the
system.
• Where steam is being used, set up the pipe configuration so that condensation can be drained
off.
• Heat the jacket to working temperature before flowing the process fluid through the meter.
CAUTION!
The maximum heating jacket pressure and temperature is 10 barg at 150
for Titanium measuring tubes and 10 barg at 100
Hasteloy and Tantalum measuring tubes.
