Output (Sub-Menu): Flow, Pressure and Temperature
The InnovaMass
®
240i and 241i comes standard with linear 4 to 20 mA analog outputs for flow,
temperature and pressure.
Navigate to the Output (Sub-Menu) screen. Use Table 13 below for guidance. You will see this
screen:
Temperature and pressure sensors are optional, so if this is a V or VT meter the 4-20 outputs will
show the T and P as inputted in the Process temperature and pressure sub-menu (see Table 9).
Table 13: Output (Sub Menu)
Use the output adjust menu to view, test, or adjust the 4 and 20mA raw digital DAC counts value
for these parameters as well as to view or adjust the pressure and temperature values that
correspond to 4 and 20mA. Zero flow always corresponds to 4mA and full scale flow always
corresponds to 20mA.
All values in the output menu have been calibrated and set at the factory. You only need to enter
these screens if you wish to view, adjust, or test any of the values.
Full Scale Flow
The full scale value is the flow value that corresponds to 20mA on the flow; 4-20mA analog
output. This value can be adjusted between 50-100% of the original factory calibration full scale
value found on the data tag.
