as per as nick formula it is not fullfill anoter range like
as 0-100 for level, 0-14 for PH
formula is
16*(unknow value-Low end of rang)
mA O/P = 4+ ---------------------------------
transmitter span
Suppose range is 3-15 PSI according to question what is the
psi for 4.6 mA
by the formula
4.6-4 =16*(unknow value-3PSI)
----------------------
12 PSI
0.6*12PSI
--------- = (unknow value-3PSI)
16
7.2 psi
------- = (unknow value-3PSI)
16
0.45 psi = (unknow value-3PSI)
0.45psi+3psi = unknow value psi
3.45 PSI = unknow value psi answer
