Abstract :
In the paper, the effect of installation angle of electromagnetic flowmeter in the downstream of an elbow upon measurement accuracy is studied. The values of induced voltages are calculated in the cases of different installation angles of electromagnetic flowmeter. Measurement error is introduced as the flow velocity distribution is distorted. In order to obtain the measurement accuracy, the simulated data is evaluated both on measurement correctness and measurement precision. It is concluded that the measurement error can be reduced if the installation angle is set around o 45°.
