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

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):

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

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. |

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%.
