Answer / brijesh

Because Steam density changes with change in its temperature
and pressure. So to get the correct mass flow you need to
introduce its temperature and pressure in the calculation.

Answer / sushil d. jambhulkar

THERE IS A EFFECT OF STEAM PRESSURE & STEAM TEMPERATURE ON
STEAM FLOW. TO COMPENSATE THIS EFFECT IT IS NECESSARY TO
TAKE STEAM TEMP & STEAM PRESSURE AS A REFERENCE.

Answer / sreeharsha

Generally flow measured will be represented as -- m3/sec at
NTP or STP i.e with reference to temperature and pressure,
so if don't consider temperature and pressure at which we
are measuring flow it may lead to erroneous value.

Answer / jo

its simple when the temprature increses the pressure will
be decreses and pr increases temp: decreses. there was a
relation between pr & temp, due to this may effect the flow
of steam.. means velocityof steam may decreses or increases
due to the pr. variation.

why we use impulse line of flow transmitter at 45 deg. angle both side of orifice plate.
