18.4. Scaling the engineering units
The engineering units are scaled to use integer math and as a result require a multiplier to be used
when sending the pressure set point of the desired engineering unit type. The multiplier used
depends on what type of ITV unit is being communicated with and what type of engineering unit is
selected. Please see the tables below for a full description with an example following –
ITV Unit Type – 0.1 MPa
Engineering
Units
MPa Kg/cm^2 BAR PSI kPa Counts
Multiplier 100000 10000 10000 1000 100 See Section 18.1
ITV Unit Type – 0.5 MPa
Engineering
Units
MPa Kg/cm^2 BAR PSI kPa Counts
Multiplier
100000 10000 10000 100 100 See Section 18.1
ITV Unit Type – 0.9 MPa
Engineering
