Parameters(Function 3-5 is invalid for US208MT)

1.       1.00500-K value, this setting value is 100 times the real K value

For example: the formula of the flow sensor is F=8Q, then real K=8, setting K is 800;

Range: 1-65535

Default value:500

2.      2.00002: Decimal,

Range: 1-4

Default value: 2. the display number will show like 2.35(L/Min)

3.   3.00500 – upper limit alarm value

=500L/Min means the alarm will go off when the flow rate is greater than the alarm value

Range: 1-65535

Default value:500

4.   4.001.00 – lower limit alarm value

=1.00 means the alarm will go off when the flow rate is lower than 1.0 litres/min

=0, function off

Range: 0.01-655.35

Range: 1-65535

Default value: 0, always alarm after triggerred,  when=3, alarm for 3 seconds and then off.  

 

How to calibrate

Use K (constant) to calibrate the flow rate

Frequency = K x Flow rate

If K set on 10, and the flow rate is 4 lts/min

To calibrate to 8 lts/min, change K to 5 (10x4/8)


Note:

  1. The max of the total volume is 999999L, it will start from 0 again after that.

  2. Suddon power shutdown will lose the total volume passed in previous minute.
