Instrument coefficient of vortex flow meter
Thread Content
What is the purpose of the instrument coefficient in the settings of a vortex flowmeter? Does it be possible to make changes, and is it related to the accuracy of the measurement values? If it can be changed, how can the instrument coefficients be adjusted according to the actual conditions on site? I hope the experts can provide an answer. Thank you.
There are many coefficients, and they can generally be changed. Signal acquisition intensity and range are the main parameters that are modified. Compensation will be provided as appropriate depending on the circumstances.
The meter coefficient is calibrated at the time of manufacture, and it should not be changed under normal circumstances. Altering this coefficient is equivalent to making fundamental changes, which will result in the vortex flowmeter losing its accuracy benchmark
Nonsense; vortex flowmeters can be modified on-site, and without such modifications they can’t be used effectively in many cases.
The instrument coefficient is determined during factory calibration and cannot be modified on-site; changing the instrument coefficient directly affects the measurement accuracy
Oh, that’s a good way to use it; I don’t use it that way anyway
The manufacturer only provides the products; sometimes the range settings within them aren’t changed, and the manufacturer isn’t very familiar with the specific operating conditions. It’s necessary to make adjustments on-site, as well as to determine whether the signal capture strength needs to be modified – does the manufacturer understand this? There was also talk about calibration earlier, but that’s complete nonsense. Mass flow meters do have calibration, and that takes place at the factory level; who would go and calibrate vortex flow meters?

The meter coefficient is determined by the manufacturer during the calibration of the vortex flowmeter based on the parameters provided by the user; it cannot be changed, otherwise the measurements will be inaccurate.
LZ, what do you mean by the instrument coefficient? If it’s a calibration coefficient, then it generally shouldn’t be modified; doing so would equate to altering the original calibration data, and in that case the flow meter would no longer have any accuracy at all. It can only approximate the value you think is correct. It’s better to avoid such deceptive tactics – addressing the measurement issues fundamentally is the proper approach! !
