This compact totalizer is designed to be used primarily with mass flow meters and mass flow
controllers. It can also be used in conjunction with other types of instrumentation with 0 to 5 Vdc
signal outputs.
The totalizer takes analog output flow signals of either 5 to 10 Vdc, from GFM mass flow meters
and GFC mass flow controllers, or 0 to 5 Vdc from AFC mass flow controllers, AFM mass flow meters
and other compatible products (jumper selectable).
The totalizer integrates and accumulates up to 7 digits of direct engineering units for the given
gas and flow rate (i.e. standard liters, standard cubic centimeters, etc.).
In order to reduce low signal (noise) totalizing, provision is made for 1% cut off.
A built-in battery back-up holds the total reading for up to 20 years.
The totalizer can be connected to GFM mass flow meters or GFC mass flow controllers via either a
modular jack replacing the LCD display or with an additional connector in parallel with the LCD display.
Each totalizer is shipped from the factory with adjustments made for specified flow rates. The
totalizer can be re-scaled for a different flow range or engineering unit.
