Electric heat tracing in dual chamber bypass level gauge

[Nuno Coelho]

Hi gents,

I have to design electrical heat tracing in a dual chamber bypass level gauge, but so far I couldn't find any tips or standards on how to put the electrical cable around the gauge correctly. Basically the gauge has two flanged process connections and two tubes in parallel, on the top of each tube there is a guided wave level transmitter. Does anyone know how to do it properly?

Thank you!

Have you asked the maker? They likely will have the best understanding of how the applied heat would least affect the accuracy.

Actually the instrument is already bought. It is a dual chamber bypass level gauge from Vega. But the power supply available on site is 120 VAC and because of that they cannot ensure ATEX rating for their heat tracing. For that reason we have to go for an independent heat tracing supplier and install the system by ourselves.
