ITABAR Flow Sensor Type 

FTMD 

Operating manual

 

 

5.2 Vertical Pipe Arrangement 

The ITABAR Sensor for flow measurement of 
steam and satured steam can be installed in vertical 
pipe runs at any location, however, the instrument 
connections have to be located in the same 
horizontal plain (see Figure 4).

5.3 Horizontal Pipe Arrangement 

For flow measurements in a horizontal pipe the 
ITABAR Sensor must be installed in the lower half 
of the pipe circumference; the connections to the 
instruments have to be located below the pipe axis.

5.4 Misalignment 

The ITABAR Sensor operates on the basis of 
simple physical principles. 
The sensor is not affected by being slightly out of 
alignment. 
The influence on the accuracy of the measurements 
is negligible as long as the limits indicated in 
Figures 6, 7 and 8 are not exceeded.
