Note!

If bypass or stilling well was selected in the "tank shape" (002) function, the pipe diameter is requested in the following step.

Function "pipe diameter" (007)

⇒

– + E

This function is used to enter the pipe diameter of the stilling well or bypass pipe.

Microwaves propagate slower in pipes than in free space. This effect depends on the inside diameter of the pipe and is automatically taken into account by the 7500 RTG. It is only necessary to enter the pipe diameter for applications in a bypass or stilling well. If mounting the 7532 RTG on stilling wells with a widening of the pipe, the inner diam- eter of the lower part of the pipe (d2 in the Fig.) must be entered. This is the part of the stilling well, where the measurement is actually performed.

Function "dist./ meas. value (008)"

⇒

– + E

The distance measured from the reference point to the product surface and the level calculated with the aid of the empty adjustment are displayed. Check whether the values correspond to the actual level or the actual distance. The following cases can occur:

•Distance correct – level correct -> continue with the next function, "check distance" (051)

•Distance correct – level incorrect -> Check "empty calibr." (005)

•Distance incorrect – level incorrect -> continue with the next function, "check distance" (051)
