AW-Lake Introduces Clamp-On Ultrasonic Flow Meters that Install on Outside of Pipes

Oak Creek, Wisconsin – August 25, 2020 – AW-Lake introduces a new series of Clamp-On Ultrasonic Flow Meters that fasten on the outside of vertical or horizontal pipes ranging in size from ½” through 48”. Housed in a water- and dust-tight NEMA 4X polycarbonate enclosure, the Clamp-On Ultrasonic Flow Meters are compatible with a range of metal and plastic pipe materials and “difficult liquids” such as chemicals, viscous liquids, and abrasives that would damage standard flow meters. As a result, the non-intrusive, clamp-on ultrasonic sensors feature enhanced flow measurement with no pressure drop in a range of applications such as food or chemical processing plants, oil refineries, and more.

Operating from 100 – 240VAC, the Clamp-On Ultrasonic Flow Meters offer an isolated 4-20mA output that can transmit flow readings to remote displays, recorders, or controllers. The programmable relays are useable for flow control, pump protection or flow proportional pulse. A built-in keypad and simple menu system simplify calibration and programming of pipe diameter, pipe material, liquid types and measurement units. Users can choose to display and totalize flow readings in preferred volumetric engineering units including gallons and liters.

一个128MB的数据记录器是标准的,能够捕捉高达26万个数据点的。通过RS-485或HART®通信协议可用于连接到自动化系统,使用户能够接收瞬时流量,体积和总运行小时,和诊断信息可选MODBUS®RTU。除了被密码保护,AW-Lake的新超声波流量计保留所有设置,价值观,并在电力中断病例总数。

How It Works

In operation, the Clamp-On Ultrasonic Flow Meters utilize the “different transit time” ultrasonic principle of measurement to measure flow from the outside of pipes by calculating the time of flight difference for ultrasonic sound pulses transmitted between two sensors that are placed on the measuring tube. Each sensor can alternately transmit and receive ultrasonic signals, while simultaneously measuring the signal transit time.

当管的液体开始流动,the signals are accelerated in the direction of flow, but delayed in the opposite direction. By comparing these differences with precision timing circuits, the Ultrasonic Flow meter can accurately calculate the flow rate.

设计成在-40°F的温度下,以300°F(-40℃至150℃)下操作,该夹式超声波流量计提供的从1.5到40英尺/秒读取±1.0%的测量精确度(为0.5到12.0米/秒)和低于1.5英尺/秒的速度±0.015英尺/秒(±0.0046米/秒)(0.46米/秒)。
