涡街流量计现场安装注意事项！西安华恒仪表介绍：涡街流量计主要用于工业管道介质流体的流量测量,如气体、液体、蒸气等多种介质。
Points for Attention in Installation of Vortex Flowmeter on Site!Xi'an Huaheng Instrument:Vortex Street Flowmeter is mainly used to measure the flow of medium fluids in industrial pipelines,such as gases,liquids,vapors and other media.
其特点是压力损失小,量程范围大,精度高,在测量工况体积流量时几乎不受流体密度、压力、温度、粘度等参数的影响。无可动机械零件，因此可靠性高,维护量小。仪表参数能长期稳定。
Its characteristics are small pressure loss,wide range and high accuracy.It is almost independent of the parameters such as fluid density,pressure,temperature and viscosity when measuring volume flow rate under working conditions.No mechanical parts,so high reliability,small maintenance.Instrument parameters can be stable for a long time.
涡街流量计采用压电应力式传感器,可靠性高,可在-20℃～+250℃的工作温度范围内工作。有模拟标准信号,也有数字脉冲信号输出,容易与计算机等数字系统配套使用,是一种比较先进、理想的流量仪表。
Vortex flowmeter adopts piezoelectric stress sensor,which has high reliability and can work in the range of-20~250~C.It has analog standard signal and digital pulse signal output.It is easy to be used with computer and other digital systems.It is an advanced and ideal flow meter.
涡街流量计在选择安装现场和仪表的安装位置时应注意以下几点：
The following points should be paid attention to when choosing the installation site and the installation location of the instrument for vortex flowmeter:
1、尽可能避开强电设备、高频设备、强开关电源设备。仪表的供电电源尽可能与这些设备分离。
2、避开高温热源和辐射源的直接影响。
3、避开高湿热环境和强腐蚀气氛的影响。
4、减小强振动（特别是管道振动）的影响。
5、选择安装、布线、维修方便的场所。
1.Avoid high-power equipment,high-frequency equipment and strong switching power supply equipment as far as possible.The power supply of the instrument should be separated from these devices as far as possible.
2.Avoid the direct influence of high temperature heat source and radiation source.
3.Avoid the influence of high humidity and heat environment and strong corrosive atmosphere.
4.Reduce the influence of strong vibration(especially pipe vibration).
5.Choose places where installation,wiring and maintenance are convenient.
