"Pressure value 2" parameter and "Scaled variable value 2" parameter
The pressure present is displayed in the operating tool on the same settings page in the
"Pressure" field.
1. Enter the pressure value for the lower calibration point via the
Pressure value 1
parameter: 50 mbar (0.75 psi)
Menu path: Application → Sensor → Scaled variable → Pressure value 1
2. Enter the volume value for the lower calibration point via the
Scaled variable value 1
parameter: 0 l (0 gal)
Menu path: Application → Sensor → Scaled variable → Scaled variable value 1
3. Enter the pressure value for the upper calibration point via the
Pressure value 2
parameter: 450 mbar (6.75 psi)
Menu path: Application → Sensor → Scaled variable → Pressure value 2
4. Enter the volume value for the upper calibration point via the
Scaled variable value 2
parameter: 1
000 l (264 gal)
Menu path: Application → Sensor → Scaled variable → Scaled variable value 2
Result: The measuring range is set for 0 to 1
000 l (0 to 264 gal). Only the
Scaled variable
value 1
parameter and
Scaled variable value 2
parameter are set with this setting. This
setting has no effect on the current output.
Low flow cut off (square root extraction)
With the
Low cutoff
parameter, positive zero return can be configured in the lower measuring
range.
