5.6.2. Changing the standard conditions
The flowmeter is factory-set to standard conditions conforming to DIN 1343.
Factory setting: P
0
= 1013.25 mbar, t
0
= 0°C (273.15 K)
The corrected volume flow measured value is calculated in line with the standard conditions set.
5.6.3. Pressure compensation
In order to achieve the highest accuracy the actual process pressure can be entered in the field “process pressure”.
Clicking the button “send” only the value of the process pressure will be uploaded to the flowmeter (transmitter).
5.6.4. Setting the pipe diameter
The actual inner diameter of the pipe must be set here. The “Send” button is used only to send the pipe
diameter to the transmitter.
5.7. External pressure transmitter for pressure compensation
In order to achieve the highest accuracy, the input from an external pressure transmitter will be very useful if
the pressure fluctuates strongly (e.g. 3 to 10 bar (45 to 150 psi)). An absolute pressure transmitter with a
2-wire loop powered 4 – 20 mA output should be used.
On the tab “Pressure transmitter” the measuring range can be entered.
