Instrument range it is used to correspond to the current 4-20MA, when the vortex flowmeter with flow totalizer need to instrument range and totalizer range set to the same, when the PLC system or DCS need to use the flowmeter signal, to set their ranges to the same.
When the vortex flowmeter is used on its own, the general range menu is not very useful, and there is also a situation where the menu of the vortex flowmeter powered by lithium batteries does not have a meter range function.
Decimal point positioning it is used to change the position of the decimal point, the user can set the appropriate decimal point position according to the needs of the general vortex flowmeter in the factory has been the decimal point positioning, see the instrument generally do not make any changes.
Fullness frequency it refers to the vortex flowmeter range corresponds to the frequency value, in the early flowmeter need to correspond to it and the instrument range settings, now do not need to set it.
Instrument coefficient it is a core parameter in vortex flowmeter. In the factory has been adjusted, will be in the factory nameplate and certificate of compliance with the instrument coefficient of this item, no one can make changes.
Small signal excision general industrial enterprise users will have a certain amount of vibration, so it will produce false flow signals, will have a certain impact on the vortex flowmeter measurement, and the small signal excision function can just remove the false flow signals.
Other vortex flowmeter some other parameters on the flow unit settings, linear correction function, cumulative flow zero function. General factory are set up, do not need to make any changes. When the meter is used for steam measurement, the function of the circuit board has changed. Users must be in the vortex flowmeter manufacturer's technical staff under the guidance of the operation.
The above is the vortex flowmeter manufacturers to provide you with the vortex flowmeter debugging and setting of the main parameters, you can do some reference based on these contents, I hope to help users in the use of the process to understand more about the maintenance of the way to reduce the instrument in the use of the process of the measurement of the error, and often on the instrument for the maintenance and maintenance of the instrument can be effective in improving the performance of the instrument.
