The first screen after selecting “Totalizer” is the following:
In this screen you can choose the flow direction for which you want to configure the action
that the totalizer will do.
Positive flow is defined as the one that appears unsigned on the default screen, and
negative flow the one that appears with a — sign on the default screen.
Once the flow rate direction is chosen, a screen with the different actions is shown:
If "Null" is selected, the totalizer remains unchanged. If "Increase" is selected, the totalizer
will add the amount of fluid passing through the flowmeter, and if you select "Decrease",
the totalizer will subtract that amount.
Examples:
a)
Installation in which for a time the product flows through the pipe and after that a
cleaning process in reverse is performed. The programming will be:
Positive flow rate action: Increase
Negative flow rate action: Null
b) Installation in which for a time the product flows through the pipe to a tank, and
after that a quantity of the product comes back in the opposite direction. The
programming will be:
Positive flow rate action: Increase
Negative flow rate action: Decrease
The totalizer will indicate the volume of product that there is in the tank.
b) Installation in which for a time a first product flows through the pipe, and after that
a second product flows in the opposite direction. The programming will be:
Positive flow rate action: Increase
Negative flow rate action: Increase
The totalizer will indicate the volume corresponding to the sum of the two
products.
