The flowmeter has high measurement accuracy and stability. Liquid level measurement error: ≤ 0.5mm; flow measurement error: ≤± 1%. The measurement data comparison process and result output are stable, and the measurement accuracy is relatively high in the same industry. Measurement error is an important indicator parameter for measuring the performance of a flowmeter as a weighing instrument. The smaller the error, the wider its application range and the more accurate the measurement.
