Level in tank under vacuum (Ex: Condensate Tank of Power
Plant)is measured using D. P. type level transmitter. Tank
is subjected to vacuum of 755mmHg. Is it possible to fill
wet leg ( i.e. leg connected to top of vessel with low
point of D. P. xmtr) with water?. Are there chances of
water getting sucked under vacuum? if yes, what is the
solution?
Answer Posted / varatha
no ..it won't suck. up to particular temp and pressure. we can fill by isolating the condensate pot
