The error of the loading flow meter is relatively large
Thread Content
The dimethyl ether loading system in our factory has a significant loading error; generally, the number of flow meters used is greater than the number used for weighing, and mass flow meters are employed. I would also appreciate some advice from those who are more experienced. Happy Year of the Chicken
Has it always been like this? Is it an Emerson mass flow meter?
Temperature and pressure compensation? Problems with the temperature sensor probes in the procuratorate are common in winter.
Pulse accumulation is the best option for flowmeters； The flow meter cannot be installed too close to the pump outlet
The accuracy of a mass flow meter is much higher than that of a scale. If the mass flow meter is properly set, shows no zero drift, and has passed calibration by the metrology department, it should be the value given by the mass flow meter that is used as the reference.
The inlet valves should be closed to some extent, in order to control the flow rate within a suitable range with relative accuracy.
Hehe, how do I answer this question? Mass flow meters are generally used for loading processes; they have high precision, and once calibrated, they can be considered reliable measuring instruments. In loading operations, mass flow meters are used to determine the amount of material transferred, with checks carried out using scale devices at the entry and exit points. In your case, it’s clearly a problem with the flow meter. . . Re-calibrating and adjusting – could this also be directly related to the medium? I don’t know the properties of dimethyl ether
Is there thermal and pressure compensation, and is there any gasification occurring?
Vaporization occurs in summer but not in winter; the error varies from time to time
The accuracy of mass flow meters is higher than that of load cells; please don’t mislead the original poster, okay? With a precision of one thousandth, can its quality be compared to that of a grade-3 scale? Compared to stability and reliability, quality is utterly worthless
