When using the totaliser function (consumption meter m³), the display value
must be multiplied by 1000.
As of DN 150 the display range with 4-digit representation of the m³/h is in-
sufficient. The display value is to be multiplied by 1000.
Based on the small size, the sensor only has a small contact surface. The
pressure loss is thus negligible (typ. 1 mbar).
