2.5.2 Flow-through chamber
The diagram below shows the use of a flow-through chamber. This provides a compact installation
and is particularly suited to flows of contaminated fluids, since the design of the chamber encourages
self cleaning. Because the volume flow rate is low, the heat flow is low and therefore the insulation
must be as efficient as possible. The low heat flow makes this system ideal for base (or referred)
viscosity measurement using heat exchangers.

Always install the chamber with flow
in horizontal and flow out vertically
upwards.
Drain, to purge solids, is vertically
down and can be vented and/or
returned to line.
