1. Parameter setting after replacing the sensor of Yokogawa electromagnetic flowmeter
The parameter setting after replacing the sensor of Yokogawa electromagnetic flowmeter dispersion measuring instrument needs to focus on calibrating the sensor coefficient, ensuring the matching of the measuring aperture, and adjusting the auxiliary functional parameters. 1. Core parameter setting and measurement diameter: It must be completely consistent with the actual diameter on site. If the diameter parameter is incorrect, it will cause deviation in flow calculation. Sensor coefficient value matching: This value needs to be strictly matched with the original parameters of the converter or the labeled value on the sensor nameplate, usually represented by the "K coefficient", which directly affects the signal conversion accuracy. two Auxiliary parameter adjustment, flow unit and display digits: Set the unit according to the working condition requirements (such as excavation failure m ³/h, L/min), and define the integer and decimal digits for flow display. Cumulative flow unit: Usually cubic meters or liters are selected as the cumulative value unit, which needs to be consistent with other instrument units in the system. Measurement of damping time: Used for smoothing flow fluctuations, the default value is generally 2-5 seconds. If the working fluid fluctuates greatly, it can be appropriately extended. Small signal cut-off point: It is recommended to set it to 1% -5% of the full range to avoid false counting caused by pipeline empty pipes or small flows. three After completing the parameter settings, it is necessary to verify the zero drift and range linearity through simulated signals or actual water testing.
