- Auto1 – the maximum time interval between pulses for minimum flow

- 16 [s];

- FUnCt – mathematical functions - for frequency measurement should

be set to oFF;

- Cnt1 – set to value 1 (averaging current measurements every second).

Then set the individual characteristics:

- IndCp – set 2 points;

- X1 – set – 0 [Hz], Y1 set the corresponding flow 0 m

/h;

- X2 – set 1 pulse – 1 [Hz], Y2 set the corresponding flow 3600 m

/h.

Example 2 Programming the analog output: if you want to program the

analog output as a signal 4...20 mA proportional to flow: 4 mA - 0 m

/ h,

20 mA - 125 m

/h, set the output parameters as follows:

- P_An – set InP1;

- AnL set the value 0;

- AnH set the value 125;

- typA set the type 4_20A (4..20mA).

Example 3 Programming the alarm output working with time delay:

if we want the alarm 1 to work in the range of flow from 1 m

to 30 m

/h and to be activated after 10 seconds, set the alarm parame-

ters as follows:

- P_A1 – set InP1;

- PrL1- set the value 1;

- PrH1 -set the value 30;

- typ1 -set the type on;

- dLY1- set the value 10;

- LEd1 – if an alarm indication is needed, it should be set to on, otherwise to oFF.
