# K05 Totalizer Scale

### Definition

Adjusts the totalizer accumulation rate without changing instantaneous flow values. K05 scales the amount added to the totalizer each cycle, allowing the totalized value to be increased or decreased. Default: 1.0.

Operates according to the formula:

$$
\text{New Totalizer Value} = \text{Previous Totalizer Value} + K\_{05} \times \text{Volume Added This Interval}
$$

```
Example:
Customer requirement: Display cumulative total as weight while keeping instantaneous flow in L/min. 
Liquid density: 1.20 kg/L.
Settings: (K05 = 1.20)
Calculation:
* Previous totalizer: 250.00 L
* Current instantaneous flow: 150 L/min → Volume in 1 second = 2.5 L
Formula:
New Totalizer＝Previous Totalizer + (K05 Current Volume)
Result:
New Totalizer 
= 250.00 + (1.20 x 2.5) 
= 250.00 + 3.00 
= 253.00 (kg)
```

### Notes

1. This setting does not affect previously accumulated data.
2. Adjusting (K05) scales both forward and reverse flow proportionally.
3. K05 must be a positive value.
