Answer / ankurjha

When two dissimilar metals are joined at two junctions, and
these junctions are subjected to different temperatures, a
potential difference develops across these junctions. This
gives rise to flow of current between two junctions. (As
per Seebeck). Voltage Difference induced, V= Seebeck Const*
(Temp difference) between the two junctions.
This is because the two dissimilar metals behave
differently to the temperature difference, thereby inducing
current flow in the loop.

If a flow transmitter (magnetic type FT) that can measure flow and temperature, then why in some industries people use flow transmitter and temperature transmitter in the same line 1 after another? Even after 1 single flow FT is capable of measuring flow as well as temperature.
