Alicat Totalizer Tutorial: Laminar DP Instruments
To operate totalizers on Alicat Coriolis and MEMS thermal flow instruments, see the CODA manual and BASIS manual .
While a meter measures the rate of flow at any given moment, a mass flow totalizer measures the total accumulated mass of a particular gas (or gas mixture) that has been flowed in a process. The totalizer function can also be used with a mass flow controller to dispense batches of set amounts of gas.
To use the totalizer on controllers and meters with displays, see below for instructions.
10v Firmware
Select: MENU > SETUP > Sensor > Totalizer > Totalizer 1 or Totalizer 2
- M AVG or V AVG shows totalizer averaging, which displays average flow rate since last reset, updated live.
- SLPM (or another measurement of mass flow) displays the live flow rate. Press to change engineering units.
- SETPT displays the current setpoint on controllers. Press to set or clear a setpoint.
- PEAK displays the peak flow rate since the last totalizer reset.
- BATCH selects the quantity to be dispensed in each batch. -NONE- appears if the batch mode is off. Only available on controllers.
- RESET clears all totalized data and immediately resets the timer to 0. Starts a new batch immediately, if the controller has a non-zero setpoint.
- MENU enters the main menu.
- NEXT moves to the second totalizer (if enabled)
See the manual to enable and configure further settings.
Older Firmware
9v firmware
Select: MAIN DISPLAY > NEXT (totalizer menu)
- TOTAL/TIMER toggles between totalized flow and elapsed time as the highlighted parameter in the center.
- SETPT displays the current setpoint. Press to set or clear a setpoint.
- SLPM (or another measurement of mass flow) displays the live flow rate. Press to change engineering units.
- (Optional) M AVG or V AVG: Shows totalizer averaging, which displays average flow rate since last reset, updated live.
- SL: Alternating display of selected engineering units for flow or time and the selected gas.
- BATCH selects the quantity to be dispensed in each batch. -NONE- appears if the batch mode is off.
- RESET clears all totalized data and immediately resets the timer to 0. The next batch, if set, begins immediately.
- MENU enters the main menu.
See the 9v manuals to enable and configure further settings.
8v firmware
Step-by-step instructions (front panel)
- Press the bottom right button for “TOTAL” selection.
- If desired, press the top right button to toggle the largest displayed value between totalized flow and time.
- If desired, press the bottom middle button to “RESET” the totalizer.
- Press the bottom left button for “BATCH” selection.
- Use the up, down, and select digit buttons to set your desired batch size.
- Press the bottom right button for “SET” selection.
Note: The batch will begin immediately with a non-zero setpoint.
