UIC HTU settings   

 
 
Calibrating of UIC's pulse output signals
is via
3 rotary select switches (numbered 0-9)
marked
H (Hundreds), T (Tens) and U (Units).
 

Use small flat-bladed screwdriver,
insert into switch slot and
turn arrow to desired number.

 

 

 
     


Formula to calculate HTU settings

UIC card with STANDARD x10 pulse input multiplier

UIC card with x50 pulse input multiplier

 

 

 

 

HTU =

input pulses/Litre

x 5

HTU =

input pulses/Litre

x 25

 

output pulses/Litre

 

 

output pulses/Litre

 

 

 

 

e.g. to convert 20 pulses/Litre to 1 pulse/Litre:

e.g. to convert 7.3 pulses/Litre to 1 pulse/2 Litres:

 

 

 

 

 

HTU =

20 pulses/Litre

x 5

HTU =

7.3 pulses/Litre

x 25

 

1 pulse/Litre

 

 

0.5 pulse/Litre

 

 

 

 

 

HTU =

100 (i.e. H=1 T=0 U=0)

HTU =

3 6 5 (i.e. H=3 T=6 U=5)

 

Admix batching with MES20 flowmeters and UIC

For batching with concrete admixtures, the MES20/MES20-S 20mm 1000 pulses/Litre flowmeters are primarily used.
For pulse scaling setpoint values, refer to the the following table (for a x10 input standard UIC card):

per pulse

If the liquid collected is more than pulse value shown on computer screen,

0 2 5

200 pulses/Litre

5 ml/pulse

then decrease the rotary decade set value by the same % difference.

0 5 0

100 pulses/Litre

10 ml/pulse

 

1 0 0

50 pulses/Litre

20 ml/pulse

If the liquid collected is less than pulse value shown on computer screen,

1 5 0

33.3 pulses/Litre

30 ml/pulse

then increase the rotary decade set value by the same % difference.

2 5 0

20 pulses/Litre

50 ml/pulse

 

5 0 0

10 pulses/Litre

100 ml/pulse

Note: Final calibration can also be performed via computer software scaling.

9 9 9

5 pulses/Litre

200 ml/pulse

All values are starting reference values for RPFS-P and are approximate only,
due to possible variations in installation conditions
e.g. due to pipe direction, water quality etc.
Values could vary up to 10%.
