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.
