Answer / sajid ali khan

Dear the Flow range is not just a function of the flow
transmitter. It is function of the Flow Element, that can
be an Orifice or a venturi, etc.
You have to know the Flow calculations and then calculate
the relationship of dp vs flow

Answer / sivaram

Dear bro.In flow calculation Need Design DP and Q Parameters,Then configure range DP ,out put function Sq root display range configure Given Q,Simple you will get Exact
flow

Answer / kirubakaran

example:
50% range =squareroot of(d.p/max-min)
50/100 = square root of(dp/5000-0)
take square on both side
2500*5000/10000= d.p(differential pressure)
1250mmwc= d.p
similiarly find 0%,25%,75%,100% this is for square root output

pls see range in dcs example 0-50ton
then put corresponding value
range o/p(ma) mmwc tons
0% 4 0 0

25% 8 312.5 12.5

50% 12 1250 25

75% 16 2812.5 37.5

100% 20 5000 50

if u feel correct means follow this

capillary type tranmitter using remote seals and capillary tubes filled with liquid of known of known density so if you wanna callibrate it just close block valve just before capilary @ high side & connect druck apply it's calibrated range pressure as normal calibration ensure low side block valve must be closed & if you asking commissioning so this is not a DP type pressure tx so simple if you wanna put in servie this tx just open high side block valve & than low side block same way i do it but still transmitter showing -13 ma.just tell me what i want to do ?
