Answer / madani

Question:Flow in Engineering unit is 40 Tons/hr.
Transmitter calibrated range is 0 to 100 mm/H2o.

For 42 Tons/Hr flow engineering unit,what will
be calibration range of Transmitter.

old flow/new flow = SQ root of old range/SQ root of new range.

Q1= 40 tons/hr, Delta P1 100 mm/h2o
Q2= 42 tons/hr, Delta P2 ?

40/42 =SQ root of 100/SQ root of new range.
Sqaring both sides

Delta P2= 42 sqare X 100/40 sqare.

1764 X 100/1600
Delta P2= 110.25 mm/H2o

For 42 tons/hr engineering unit,the Transmitter to be calibrated for 110.25 mm/h2O.

Answer / hiren

tx range:- 0 to100mmh2o= 0 mmh2o= 0 ton/hr,100mmh2o=40ton/hr,42ton/hr=?
100/40*42=105mmh2o. so tx range is 0 to 105 mmh2o
