| 摘要 |
The present invention relates to a flowmeter. The flowmeter comprises: an upper magnet and a lower magnet which are arranged on an upper and lower side of an outer wall of a measuring tube, a left detection electrode and a right detection electrode which are arranged on a left and right side of the outer wall of the measuring tube, a signal processing circuit connected to the left detection electrode and the right detection electrode, a left shielding electrode and a left shielding ring which are arranged outside the left detection electrode, and a right shielding electrode and a right shielding ring which are arranged outside the right detection electrode. The flowmeter provided in the embodiments of the present invention has low power consumption, small nonlinearity, a strong anti-interference capability, and a relatively wide application range. |
