ITABAR Flow Sensor  Type  

IBF 

 Operating 

Manual 

 

When installing multi- directional valve block, make 
sure that all bolts are tightened uniformly and 
opposite bolts are tightened in sequence. 

 

7.2 

p-Transmitter: 

For liquid measurements, the differential pressure 
transmitter should always be installed below the 
ITABAR sensor in order to avoid the occurrence of 
air bubbles in the instrument connections (see 
Fig. 13).

When measuring dry gases and air, the differential 
pressure transmitter should always be installed 
above the ITABAR sensor in order to avoid 
measurement degradation due to condensation and 
presence of solid particles (see Fig. 14).

7.3  ITABAR sensor with flange plate 

By using of the flange plate version, you can 
mounting the 

p-transmitters direct onto the flow 

senor (s. fig. 15). By this version you don`t must 
install differential pressure lines and screwed 
connections. In combination with a multi- 
directional valve block is this version the best 
solution. 
When installing multi- directional valve blocks, 
make sure that all bolts are tightened uniformly and 
opposite bolts are tightened in sequence.
