Uncorrected flow velocity

For special applications, the uncorrected flow velocity might be of interest.
The  profile correction for the  flow velocity is  activated in 

Special  Funct.\SYSTEM  settings\Measuring\Flow

Velocity

.

• Select 

normal

 to display and output the flow velocity with profile correction.

• Select 

uncorr.

 to display and output the flow velocity without profile correction.

• Press ENTER.
If 

uncorr.

 is selected, each time the program branch 

Measuring

 is selected it will be requested whether the profile

correction is to be used or not.

If 

no

 is selected, the profile correction will be switched off. All physical quantities will be calculated with the uncorrected

flow velocity.
During the measurement, the designation of the physical quantity is displayed in capital letters to indicate that the value is

uncorrected.

• Press ENTER.

If 

yes

 is selected, the uncorrected flow velocity will only be used if the flow velocity is selected as physical quantity in the

program branch 

Output Options

.

All other physical quantities (volumetric flow rate, mass flow rate, etc.) will be determined with the corrected flow velocity.
During the measurement, the designation of the physical quantity "flow velocity" is displayed in capital letters to indicate

that the value is uncorrected.
• Press ENTER.
In both cases, the corrected flow velocity can also be displayed.

Press key 

 to scroll until the flow velocity is displayed. The uncorrected flow velocity is marked with an "

U

".

Uncorrected flow velocities transmitted to a PC are marked with 

uncorr.

FastFood mode

The FastFood mode allows to measure high dynamic flows. A continuous adaptation to changing measuring conditions is

only partially realized in the FastFood mode.
• The sound speed of the fluid is not updated. The last measured value of the sound speed before toggling to the

FastFood mode is used.

• The outputs can still be used. They are actualized every 100 ms independently from the storage rate.
• The measured values are stored with the storage rate of the FastFood mode, see 16.8.2.
• The FastFood mode has to be enabled and activated.
