When  the sensor is inserted into a liquid or gas  the heated RTD is strongly affected 
by  the  velocity  of  the  medium.    Flow  past  the  heated  RTD  changes  the  heat 
transferred  from  the  surface  of  the  sensor.    This  cooling  effect  reduces  the 
temperature  of  the  sensor.    The  Innova-Switch

™

  compares  this  change  to  a  preset 

flow  trip  point  to  switch  the  output.    Figure  2B  shows  the  model  FS4200  signal 
change vs. flow rate for air, light hydrocarbon liquids, and water.   
The signal change vs velocity has the same general shape for all three media but the 
change is larger for air and the sensitive range is different for each.  For air and most 
gaseous media the range is 0.1 to 500 feet per second (FPS).  For most liquid media 
the  range  is  0.01  to  5  FPS.    Appendices  in  section  9.0  contain  flow  conversion 
information  to  facilitate  conversion  from  various  units  and  pipe  dimensions  into  flow 
velocity in feet per second. 

 

 

 

Gas Or Liquid Flow

 

Note:

 The fluid velocity and 

heat absorption ability 
determine the differential 
between the tips. Their 
combination determines the 
measurable velocity. In 
water velocities from 0.01 to 
5 FPS are measurable, 
whereas in air velocities of 
0.1 to 500 FPS can be 
measured.  

 

For a no flow condition the 
thermal differential between 
the two tips is high because of 
relatively low heat transfer.  

Flow across the tips decreases 
the thermal differential 
because of the higher heat 
transfer of flowing fluids. This 
differential is compared with 
the trip point.   

 

 

When the lower differential 
matches the customer select 
flow velocity trip point (set 
point) the switch relay and 
red LED are tripped.  

When flow is above the trip 
point the differential is smaller 
than at the set point and the 
relay and Led remain tripped
