Cyclic Data Explained
Flow (R):
Data type: 32 bit floating point (LSB – MSB)
Description: The actual flow as measured by the instrument
Totalizer (R):
Data type: 32 bit floating point (LSB – MSB)
Description: Accumulated flow
User full scale (R):
Data type: 32 bit floating point (LSB – MSB))
Description: The user full scale value allows you to re-range the instrument. Any value between
50% and 100% of the factory full scale is allowed. The new value will also redefine the analog
outputs of the instrument (when used). The 20mA/5 VDC will represent the new full scale value.
Factory Full Scale (R):
Data type: 32 bit floating point (LSB – MSB)
Description: Factory full scale value of the instrument.
K-Factor (R):
Data type: 32 bit floating point (LSB – MSB)
Description: K-factor which can be used to adjust the flow reading
Serial Number (R):
Data type: 16 bits ASCII
Description: Serial number of the instrument (12 characters).
Flow Unit (R):
Data type: 16 bits ASCII
Description: Flow unit of the instrument (5 characters).
Totalizer Unit (R):
Data type: 16 bits ASCII
Description: Totalizer unit of the instrument (3 characters).
Status (R):
Data type: 16 bit integer
Description: Status indicates if the quality of the data in the registers (0 = bad, 1 = good).
Reset Totalizer (W):
Data type: 32 bit floating point (LSB – MSB)
Description: Accumulated flow
