Description
1 Before configuring the device for your application, the
pressure piping must be cleaned and the device filled
with fluid. See Operating Instructions BA301P, Section
6.5.1.

1 See table, step 7.
2 See table, step 8.
2 Carry out position adjustment if necessary. See Page 98,
ToF Tool, table 4: POSITION ADJUSTMENT.
3 If necessary, select the "Flow" measuring mode via the
MEASURING MODE parameter.
Menu path: OPERATING MENU → SETTINGS →
BASIC SETUP → MEASURING MODE
4 Select a pressure unit via the PRESS. ENG. UNIT
parameter, here mbar for example.
5 Select the "Volume p. cond." option by means of the
FLOW-MEAS. TYPE parameter.
6 Select a flow unit via the UNIT FLOW parameter, here
m
3
/h for example.
7Select MAX. FLOW parameter.
Enter the maximum flow value of the primary device,
here 6000 m
3
/h for example. See also layout sheet of
primary device.
8 Select MAX PRESS. FLOW parameter.
Enter the maximum pressure, here 400 mbar for
example. See also layout sheet of primary device.
9 If necessary, use the Analog Input Block to configure the
CHANNEL parameter (→ Page 67), L_TYPE parameter
(→ Page 69), XD_SCALE parameter (→ Page 73) and
OUT_SCALE parameter (→ Page 71).
10 Result:
The device is configured for flow measurement.
