Three Point Flow Sensors Linearizing Using the New Tab Function
Linearization achieves better accuracy of the flow sensor connected to the MC4000 The MC4000 is capable of using up to
three linearization points The points entered are in pairs of frequency values with their associated flow rates The linear point
pairs can be entered using the MC4000 keyboard or from a connected PC
Linearization Point Frequency (Hz) Flow Rate (Q)
1 Frequency F1 Flow Rate Q1
2 Frequency F2 Flow Rate Q2
3 Frequency F3 Flow Rate Q2
Table 1: Sample linearization table
The linearization menu makes the assignment of both the frequencies and display readings
example
Linearization Pair Number Frequency Values Flow Values
Linearization Pair 1 0 Hz 0 lpm
Linearization Pair 2 166 Hz 66 lpm
Linearization Pair 3 630 Hz 150 lpm
