Overview.
LC11 series oval gear flowmeter is a direct reading cumulative instrument, is a volumetric flowmeter to measure the total flow of liquid through the pipeline. Can be widely used in petroleum, chemical, pharmaceutical and health departments flow measurement.
◆Product implementation standards: JB/T9242-2015 (industry standard)
◆Flange general standards: GB/T 17241.6-2008 (national standards)
◆Type approval certificate: 2010F450-33
Working principle.
In the instrument measuring chamber import and export ends of the liquid pressure difference, a pair of elliptical gears on the axis of non-stop rotation and discharge of liquid, measured the number of revolutions of the elliptical gear can know the total value of liquid flowing through the instrument.
1. High accuracy and less influence by liquid viscosity.
2. No need to install straight pipe section in front of the meter.
主要是电磁流量计感应器上游或是下游直管段长度不够，影响测量精度，这方面的原因关键会导致故障。
参数整定方位的原因。因为参数不正确，造成仪表指示有误。参数不正确促使二次仪表满度频率计算误差，这方面的原因关键同难题①、③相关。满度频率相差不多的促使指示长期不准，具体满度频率大于计算的满度频率的促使指示大范围起伏，没法读值，而材料上参数的不一致性又影响了参数的最后确定，最后根据再次校准融合互相较为确定了参数，解决了这一难题。
二次仪表故障。这部分故障较多，包含：一次仪表线路板有断开之处，量程设置有个别位显示坏，K指数设置有个别位显示坏，促使无法确定量程设置及其K指数设置，这部分原因关键向难题①、②相关。面板式流量计厂商根据修补相应的故障，难题得到解决。
