Ultrasonic flow meter is used to measure the flow meter of flare header due to high accuracy and good turn down ratio.the basic data is mandatory to purchase which is required by vendor but we could not understand how to find these data,as required data is mandatory which are following.
Flow @ Max,min,operating ,
Temp @ Max,min,operating ,
Pressure @ Max,min,operating
So i am estimating the operating flow in a flare header by 0.3% of crude feed from CDU and similarly take 0.2-0.3 % of feed from other downstream unit which involve specially reciprocating compressor due to slight leakage from their stuffing boxes.
How i will find Max,min,operating flow,temp and pressure of flare header ?
we only have the flare relief load,max design temperature and pressure data available.
If any body have a idea how to estimate these data for procurement of accurate flow meter please give your technical comments?
