Device Software Functions
Measure Gross Total
Measure gross total provides the output reading of the totalizer. This
value is the amount of liquid or gas that has passed through the
flowmeter since the totalizer was last reset
Start Totalizer
Start totalizer starts the totalizer counting from its current value.
Stop Totalizer
Stop totalizer interrupts the totalizer count until it is restarted again.
This feature is often used during pipe cleaning or other maintenance
operations.
Reset Totalizer
Reset totalizer 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.
Low Flow Cutoff
Low flow cutoff allows you to specify the flow rate, between 0.04 and 1.0
feet per second, below which the outputs are driven to zero flow. The
units format for low flow cutoff cannot be changed. It is always
displayed as feet per second regardless of the format selected. The low
flow cutoff value applies to both forward and reverse flows.
Coil Drive Frequency
Coil drive frequency allows pulse-rate selection of the flowtube coils.
6Hz
The standard coil pulse mode is 6 Hz, which is sufficient for nearly all
applications.
30 Hz
If the process fluid causes a noisy or unstable output, increase the coil
pulse mode to 30 Hz. If the 30 Hz mode is selected, perform the auto
zero function as described on page 4-5.
