Installation instructions for vortex flowmeters
2011-8-8 9:14:50

的安装说明: Installation instructions of vortex flowmeter :
涡街流量计 需要单向测量,安装时要确保介质流量方向与流量计箭头所示的方向一致。 1. The vortex flowmeter requires unidirectional measurement. When installing, make sure that the direction of the medium flow is consistent with the direction indicated by the arrow of the flowmeter.
竖直安装为涡街流量计的最佳安装方式,介质自下而上通过流计。 2. Vertical installation is the best installation method of vortex flowmeter . The medium passes through the flowmeter from bottom to top. That is, the flow meter is installed on a vertical pipe, so the flow direction is from bottom to top.
水平安装时,必须在整个系统的高压区安装流量计,以确保相应的出口压力;在管路的最高点最好不要进行安装,因为最高点往往容易积聚气体,管道没有满,出口不可以直接放空。 3. For horizontal installation, a flow meter must be installed in the high-pressure area of the entire system to ensure the corresponding outlet pressure. It is best not to install at the highest point of the pipeline, because the highest point tends to accumulate gas, the pipeline is not full, and the outlet is not. Can be vented directly.
在测量高温流体时,尽量要采用竖直安装方式;如果非要水平安装的话,避免温度过高的原因,要将流量计的变送器部分竖直向下或者水平侧装,注意在安装的位置处空气流动或者通风要良好。 4. When measuring high temperature fluids, try to use a vertical installation method; if it is necessary to install it horizontally, avoid the cause of excessive temperature, install the transmitter part of the flowmeter vertically downward or horizontal side, pay attention to Good air flow or ventilation at the installation location.
对直管段的要求:至少要保证流量计前15倍的管径,流量计后5倍的管径。 5. Requirements for straight pipe sections: at least 15 times the pipe diameter of the front of the flowmeter and 5 times the pipe diameter of the back of the flowmeter.40倍的管径,流量计后6倍的管径。 If there are interference sources such as elbows, indentations, and expansions in front of the flowmeter, you need to ensure that the pipe diameter is 30 to 40 times the front of the flowmeter and 6 times the diameter of the back of the flowmeter.

在调节阀,压力或温度传感器上游处安装流量计。 6. Install a flow meter upstream of the regulating valve, pressure or temperature sensor.
在使用密封圈的时侯,注意密封圈内径要略大于或者等于仪表的内径,密封圈中心位要对准管道的中心。 7. When using the seal ring, please note that the inside diameter of the seal ring is slightly larger than or equal to the inside diameter of the meter, and the center of the seal ring should be aligned with the center of the pipe.
