เครื่องวัดอัตราการไหลของพื้นที่ “Greyline AVFM 6.1” ใช้เซ็นเซอร์อัลตราโซนิกที่จมอยู่ใต้น้ำซึ่งวัดทั้งระดับและความเร็วเพื่อคำนวณการไหลในช่องเปิดหรือท่อ วัดการไหลผ่านท่อช่องทางคลองและท่อระบายน้ำบางส่วนโดยไม่ต้องใช้ฟลูมหรือฝาย เหมาะอย่างยิ่งสำหรับน้ำเสียน้ำฝนน้ำทิ้งน้ำเสียอุตสาหกรรมและน้ำชลประทาน การกำหนดค่าทำได้ง่าย: ป้อนเส้นผ่านศูนย์กลางของท่อหรือขนาดช่องและ AVFM 6.1 จะคำนวณและแสดงปริมาณการไหลโดยอัตโนมัติ

Features
- No flume or weir required – submersible ultrasonic sensor measures velocity and level simultaneously to calculate flow. No moving parts to wear, foul, or clog.
- The built-in 5-button keypad, intuitive menu, and large backlit LCD display make the Greyline AVFM 6.1 the most operator-friendly area velocity flow meter on the market.
- Fast, simple, installation and set-up.
- Improved performance in a wider range of operating conditions.
- At a glance, view flow rate, velocity, level, totalizer, relay status, and important diagnostic information on the LCD display.
- Three isolated 4-20 mA outputs for flow rate, velocity, and level, and two relay outputs for pulse output or alarm.
- 6.5 million point data logger for greater flexibility of data monitoring, control, and reporting.
- Min, Max, and Total Flow data from the last 365 days is available on the LCD display, or download directly to a USB for easy reporting.
- Monitors flow rate, volume total, run hours, and diagnostic information through only two wires with the optional Modbus RTU serial communication output.
