I have a LT of 10000mmwc range. can i use this LT in 1000mmwc range of tank?? if yes than what happe..

Your tx's range is 0~10000mmwc if u
use it at 0~1000mmwc head press tank
than it will indicate 10% level when tank
full. So just calibrate it (configure it) at
0~1000mmwc before take inservice for
actual reading of tank at output

Answer / ys

u can use this transmitter. but u should rerange the
transmitter.(ie if tank service is water and ur lt is dry
leg type,then LRV=0 and URV=1000MMH2O.. If ur lt is wet leg
calibrated, then LRV= -1000 AND URV=0 MMH2O)

1000mmwc range of tank?? if yes than what happened???

A change from a range of 10000 mmwc to 1000 mmwc is a turn
down of 10:1

If your transmitter supports a minimum range of 1000 mmwc
within the accuracy spec you require, then re-range the

transmitter and use it.

Most smart DP transmitters from major manufacturers will
support this.
