1. The vortex flowmeter is powered on, the valve is not open, and there is signal output. Solution: ①The shielding or grounding of the output signal of the sensor (or detection element) is poor, which induces external electromagnetic interference; ②The meter is too close to the strong current equipment or high-frequency equipment, and the space electromagnetic radiation interference will affect the meter;
电磁流量计应用领域广泛。大口径仪表较多应用于给排水工程。 中小口径常用于固液双相等难测流体或高要求场所,如测量造纸工业纸浆和黑液、有色冶金业的矿浆、选煤厂的煤浆等。
流量计种类很多,不同的介质对应不同的流量计,非要说电磁流量计性能是很好的,而超声波流量计性能是不好的,不能这样定论,选择一款流量计有好多的标准,所以我们要区别对待。
