Answer / naveed iqbal buttf

we give equal pressure both side of the transmitter (high
side and low side )for 24 hour to status of transmitter
that is called static pressuere.

Answer / jawed akhtar

When the fluid is in equilibrium,the pressure at a particular
point is identical in all directions and independent of
orientation.This is called "static pressure".

Answer / carl_ellis

Static pressure is the line pressure (gauge or absolute) at
the high port when measuring a differential pressure.

Static pressure affects the DP measurement (with current
technologies) at pressures greater than 1,000 psig (69barg).
Some commercial DP transmitters (Honeywell and Yokogawa)
use an absolute pressure sensor sensing the high side port
pressure which is used to correct for static pressure error
when static pressure is greater than 1,000 psig.

A separate calculation for static pressure error is provided
for DP transmitters (by the major vendors) as part of a
total uncertainty calculation.

Multivariable transmitters (a DP transmitter with a
temperature sensor and an absolute static pressure sensor)
use the same technique of measuring (absolute) static line
pressure for calculating inferred mass flow for gases.

Answer / salim akhter ansari jamshedpur

i am agree to Mr.Naveed Iqbal Butt
Static pressure is the pressure which is not moving or flowing and that has not kinetic energy and Velocity
in flow line flow is passing the way rest of orifice but the area of restricted by orifice the flow is not passing and flowing although it is exerting force on rest side of pipe this is called Static Pressure.

I have observed in field instrumentation work... I remove the fuse of an analog transmitter then it shows 7.75 kg/sq cm (which is practically wrong value)in DCS and when put the fuse it shows 0 in dcs. Then cheach the field transmitter termination and found moister. clean that and then it shows 1.1 kg/ sq cm which is right value. Please describe the above phenomenon.

I have installed a RTD whose length is 2250mm(RTD stem length), but it's upper 200 -250mm is out of the reactor, and this upper 200mm stem is surrounded by atmospheric temp. And the lower portion i.e. 2000mm is in contact with the measuring fluid, then does the final measuring temp. Gonna change as the upper 200mm RTD stem is out of reactor?
