Rosemount Model 8800C Vortex Flowmeter
3-2
Analog Output – The analog output variable provides the analog
value for the flow rate. The analog output refers to the industry
standard output in the 4–20 mA range. Check the analog output
value against the actual loop reading given by a millimeter.
If it does not match, a 4–20 mA trim is required. See D/A Trim
(Digital-to-Analog Trim).
Totalizer – Totalizer provides a reading of the total flow of the
flowmeter since the totalizer was last reset. The totalizer value should
be zero during commissioning on the bench, and the units should reflect
the volume units of the flow rate. If the totalizer value is not zero, it
may need to be reset.
View Other Variables– Pulse Output provides the actual pulse reading
from the meter if your meter includes the pulse output option. This
digital value is always available, even without the pulse output option.
Shedding Frequency measures the frequency of vortex pulses around
the shedder bar.
Totalizer Totalizer tallies the total amount of liquid or gas that has passed
through the flowmeter since the totalizer was last reset.
It enables you to change the settings of the totalizer.
Total
Total — Provides the output reading of the totalizer. Its value is the
amount of liquid or gas that has passed through the flowmeter since
the totalizer was last reset
Start
Start — Starts the totalizer counting from its current value.
Stop
Stop — Interrupts the totalizer count until it is restarted again. This
feature is often used during pipe cleaning or other maintenance
operations.
Reset
Reset — Stops the totalizer and returns the totalizer value to zero.
NOTE
The totalizer value is saved in the EEPROM memory of the electronics
every three minutes if the temperature is less than 131 °F (55 °C) or
every six minutes if the temperature is greater than 131 °F (55 °C).
Should power to the transmitter be interrupted, the totalizer value will
start at the last saved value when power is re-applied.
