Differential pressure flow measurement is old and reliable.
With the aid of microprocessor technology now discharge
coefficient calculations can be done in real time.
This are called multivariable mass flow meters.
By other side we can use typical differential pressure
devices such as (nozzles, orifice plate , etc).
The ISO5167 standard condenses all this experimental
information giving the formulas and procedures for
manufacturing a differential pressure flow measurement
device of the standard types with a predictable uncertainty.

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.
