Industry Information
Electromagnetic flowmeter shows negative value
2011-8-23 14:47:26

   电磁流量计 流量 显示 值出现 数的原因有以下几点: In daily operation, the reasons for the negative value of the displayed value of the electromagnetic flowmeter are as follows:

电磁流量计 传感器没 按流向标识安装,造成测量方向相反。 1. The sensor of the electromagnetic flowmeter is not installed according to the flow direction mark, which causes the measurement direction to be opposite.

对传感器 重新安装。 Solution: Reinstall the sensor .
由于 电磁流量计 有正反向流量测量功能, 因此当电磁流量计的 传感器信号线接反 ,显示反向流量。 2. Because the electromagnetic flowmeter has a forward and reverse flow measurement function, when the sensor signal line of the electromagnetic flowmeter is reversed , the reverse flow is displayed.

传感器的 信号线调换。 Treatment method: exchange the signal line of the sensor .
测量管道空管或 充满管,有气体存在 时,这时会出现电磁 流量计 显示负数或 流量值忽大忽小。 3. When the measuring pipe is empty or not full, and there is gas , the electromagnetic flowmeter will display a negative number or the value of the flow will increase or decrease .

Treatment method: Fill the pipeline with the measured medium, so that the flowmeter has the measurement conditions.
