Totalizer counter Aalborg Instruments

AALBORG®'s 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 0-5 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 flowrate (i.e. standard liters, standard cubic
centimeters.

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.
