Answer / satish tumbare

above answer is not write.Density also affect level

Answer / sathya

well....suppose if you want to measure level of a
tank....connect your PG at the the bottom of the tank.for
eg. if your PG shows 5ksc pressure. then 5ksc is approx.
equal to 50000 mm WC..which is approx. 50 mtr.so level in
the tank would approx. 50 mtr.

Answer / senthil r.m

Height(level)=Pressure / sp.gravity.

So,if u fix the pressure gauge at the bottom tapping of the tank.the pressure reading is divided with the sp.gravity of the liquid in the tank.

you can cross check by measuring the level and multiplying it with sp.gravity

Answer / anish kumaran.r

Using purge tube method you can measure the level by a PG and a air regulator. But it needs suppy air. Make a 'T' setup and connect gauge at one end ,supply air at one end and another end should be inserted in to the tank where the level to be measured. The gauge shows t level of the tank we shd convert into mmwc.

Answer / anwar ali

We have to know the tank if it open or closed tank. Then we can use Hydro-static Head Pressure Theory. And of course the type of liquid (density) because the pressure depend upon of the highest and density of the liquid:
P = d x h
It is important if the tank is used as storage or there inside it some physic changing.
Anther important thing to put in our mind if the measuring system used is suppression or elevator range.
That all what we need measure level

Answer / prem

use the method density * gravity * height.

I want to use 1/2 inch SS316 tube in my high pressure & temperature (64 kg/cm2 & 500 deg C)after condensate pot in pressure tranmistter. 1) Is it possible to use 1/2" ss316 tube in high pressure and temperature line. Tube manufacturer is local vendor. 2)On sarting the plant, We need to do system fluse that time condesate is not in the condesate pot so steam is directly contact with the tube. We have no exact calculation to know our tube is ok or nor at this time. pleae,reply.
