2.9.5 Thermal insulation
CAUTION!
The flow sensor must be insulated to prevent humidity problems caused by condensation.
Please make sure that the insulation is installed in accordance with the illustration below.
In case of low-pressure steam in combination with low ambient temperature, electric heat
tracing may be applied to prevent condensation and/or to reduce startup time.
WARNING!
Keep the transducers and connection box free of insulation to allow cooling by free convection.
The transducers can reach a temperature of up to +200
°
C/+392
°
F!
