Good explanation for easy to understand.. thanks . but small observation . Calculation mistakes observed in closed tank TX formulae while submitting the values...
The drawing for L max is deceiving, it should be drawn above upper (low side) seal by 22.92". The answer for the 4mA range on the drawing for the transmitter mounted below the high side seal has an error. It reads -122.08", should be -112.08".
The author pleugerized the drawings from Emerson site ( Rosemount ) but wrote 180 in. Instead of 108" for the Lmax. Formula is correct, numbers are wrong.
This drawings were directly taken from Emerson website but the Lmax makes no sense at 180 in. Because it should be 108 in. Instead. Calculations are WRONG!. formulas used are correct.
Can you please recheck last case -- Closed tank with DP type LT Remote capillary in which Lrv is -112.08 and Urv is 22.92 . This is wrong result of lrv and urv.
