1)how we calculate the drum level? and how we select the
transmitter range?
Answer Posted / george mathews
if we are trying to measure the drum level of a drum which
contain water or (H2O) we prefer to use the Hydrastep .
Which is in my knowledge one of the trusted sencer of it
kind .
Anather by using the pressure or more preciesely the DP
transmitter. Here what we do is , we take the connection of
the higher end of the DP Transmitter from d bottm of the
drum and simulteneously we take the connection form the
upper end .where we can find the difference and calculate
the level of water it has got. as during the time of
calibration it is being feeded what ll b d pressure of the
drum when it is full and what is the pressure when it is
empty .
so it ll differenciate the difference between the actual
lever of water level of the drum.
Here the key factor is the density of Any medium , once we
know the Exact density of the Medium we can find the level
easely with the DP Transmitter.
