高度精确地测量液体、蒸汽和气体，不受沉积物的影响

精度为±0.75，液体流率和±1%的气体和蒸汽

全方位的大小尺寸为试验工厂和工艺方面的应用

先进的处理器，提供了大量的监控和控制选项

模拟和HART输出

凭借强大的设计和数字信号处理，这些仪表提供所有的漩涡技术的最佳效益。为增加耐用性，阀体、卸料器和传感器都是316L不锈钢，NEMA4X（IP67）转换器外壳环氧涂层铝，可承受恶劣的过程环境。流量计的性能一样重要的是转换器的设计，所有的编程可以通过集成三键键盘或通过使用ABB磁棒和选择参数从编程菜单无需打开转换器外壳来完成。

当编程单元，可以设置发射器参数的模拟输出和超限报警输出流量或脉冲输出。电子允许用于过滤和/或输出的一个低流量截止到在波动的流动条件的情况下限制控制中断，所有设定的参数都存储在一个孤立的EEPROM长达10年无电源。

为了提供最佳的功能，涡式流量计的流量分布应尽可能不受干扰越好。这是通过使用一个直的入口部分的长度的管的直径的15倍，并在管道直径的5倍的出口部分来实现的。

Analog and HART out

With a robust design and digital signal processing, these meters provide all of the best benefits of vortex technology. The body, shedder, and sensor are all 316L SS for added durability. The NEMA 4X (IP67) converter housing is epoxy-coated aluminum that can withstand harsh process environments. Just as important to the performance of the flowmeter is the design of the converter. All the programming can be done either through the integrated three-button keypad or by using the ABB Magnet Stick and select parameters from the programming menu without opening the converter housing.

When programming the unit, you can set transmitter parameters for the analog output and a limit alarm output for flowrate or pulse output. The electronics allow for filtering and/or a low flow cutoff of the output to limit control disruptions in the event of fluctuating flow conditions. All programmed parameters are stored in an isolated EEPROM for up to 10 years without power.

In order to provide optimum functionality, the flow profile of the vortex flowmeter should be as undisturbed as possible. This is achieved by using a straight inlet section with a length of 15 times the pipe diameters and an outlet section of 5 times the pipe diameter.
