ABB 渦I流流量計，1 1/2英寸晶圓連接，液體

高度精確地測量液體、蒸汽和氣體，不受沉積物的影響

精度為±0.75，液體流率和±1%的氣體和蒸汽

全方位的大小尺寸為試驗工廠和工藝方面的應用

先進的處理器，提供了大量的監控和控制選項

模擬和HART輸出

憑借強大的設計和數字信號處理，這些儀表提供所有的漩渦技術的最佳效益。為增加耐用性，閥體、卸料器和傳感器都是316L不銹鋼，NEMA4X（IP67）轉換器外殼環氧涂層鋁，可承受惡劣的過程環境。流量計的性能一樣重要的是轉換器的設計，所有的編程可以通過集成三鍵鍵盤或通過使用ABB磁棒和選擇參數從編程菜單無需打開轉換器外殼來完成。

當編程單元，可以設置發射器參數的模擬輸出和超限報警輸出流量或脈沖輸出。電子允許用于過濾和/或輸出的一個低流量截止到在波動的流動條件的情況下限制控制中斷，所有設定的參數都存儲在一個孤立的EEPROM長達10年無電源。

為了提供最佳的功能，渦式流量計的流量分布應盡可能不受干擾越好。這是通過使用一個直的入口部分的長度的管的直徑的15倍，并在管道直徑的5倍的出口部分來實現的。

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.
