Answer / girish_b_k

transmitter has a sensor which has a temperature withstand
around 150c but actually steam line is more than 500c this
txt. cant withstand so a condensate pot is available in txt.

impulse line are connected to that pot through that a cold
dm water is poured and txt. taken in line when steam comes
it gets condenses in that pot itself so sensor will not be
affected

Answer / ashwini kumar

as the impulse line are connected to that pot through that a
cold
water is poured . taken in line when steam comes
it gets condenses in that pot itself so sensor will not be
affected

hence
the use of impulse line in AFBC boiler , WHY WE
CONNECT IMPULSE LINE TO TRANSMITTER , DRFT GAUGE ETC are
done

Answer / s vedpathak

Using DP Tx, we measure differential pressure to measure
level,flow.To measure this pressure i.e. the HP & LP
pressure , impulse tubes are required to be connected
across the capsule of DP Tx.

Answer / ak

in dp transmitter if we didnt used impulse line steam or
foreign particular amy enter to the transmitter that will
cause sensor damage thatsy for condensate the vapour
impulse lines are used.

Answer / chin

What is AFBC boiler?
Without impulse line the transmitter do not have sensor.

Answer / amit patel

In case of Level measurement boiler drum , if we are not
used impluse tube then steam directly contact with
transmitter diapharm which getting damaged beacuse of TX
diapharm can withstand maximum temp around 150 degree
centigrade. So when steam flow carrying in impluse tube
then its temp comes down due to atm temp and becomes
condensate water.
