Description of the error of the electromagnetic flowmeter

1. Accuracy level. Electromagnetic flowmeter, sewage flowmeter, sewage flow meter, tap water flowmeter within the specified flow range accuracy level, ****** allowable error should meet the requirements of Table 1. Flowmeter error indicates the use of relative indication error.
2. Reference error. For the flowmeter error indication for instantaneous flow indication, the reference error can also be used. The allowable error series should meet the requirements of Table 1. The accuracy of the test result is no longer given the accuracy level, and the * is used. ***** allows for error indication, and should also be marked with FS after the allowable error, such as ±0.5% FS.
3. Error representation method and selection principle. In a verification of a flowmeter, the flowmeter error representation method should be given according to one of the accuracy grade and the reference error; for the electromagnetic flowmeter using the relative indication error and the reference error combination to represent the error, the sewage flow rate Meter, sewage flow meter, tap water flow meter, one method should also use a method to express its error.
4. Repeatability. The repeatability of the electromagnetic flowmeter, sewage flowmeter, sewage flow meter, and tap water flowmeter shall not exceed 1/3 of the value of the allowable error ******* specified by the corresponding accuracy level. The limitation of the electromagnetic meter is that the signal output from the sensor is relatively weak, only a few microvolts to a few millivolts. This means that the electromagnetic flowmeter must be equipped with high technology, and the measured medium and the surrounding environment. The measurement accuracy of the electromagnetic flowmeter also has a great influence.
