15 3. CONFIGURING THE FLOWMETER Once the opening screen is displayed, click Unit Setup (bottom left corner of the Flow screen). This opens the Pipe page (Figure 3, below) which requires you to enter necessary application parameters. FIGURE Obtaining Pipe Inside Diameter You must know the pipe inside diameter (ID) to ensure reliable flow measurements, and there must be flow in the pipe when you start the meter. If you do not know the pipe ID, try to obtain the pipe outside diameter (OD) using one of the following methods: Read the pipe OD and schedule on the pipe. Read the OD and schedule from system drawings. Measure the pipe circumference with a tape measure, and divide the measured circumference by

16 Obtaining Pipe Inside Diameter continued Use the OD with the charts in Appendix A: Pipe ID Charts (pages 34-36) to obtain an approximate pipe ID. For a more accurate pipe ID use Thermo Fisher s Ultrasonic Pipe Thickness Gauge (part number ), and perform the following calculation: pipe ID = pipe OD (2 x pipe thickness). 3.2 Entering Pipe Parameters FIGURE Click inside the Pipe I.D. text box, and enter the pipe ID. 2. Click the arrow in the box next to Pipe Wall Material. Select the appropriate option for your application. 3. Repeat step 2 for the Pipe Units, Flow Rate Units, and Timebase selections. 4. After entering all required information, click Send. Once you send the information, the meter displays the new information. For example, if the information in Figure 3.2 above is sent to the meter, the meter then displays the flow in G/MIN. 3.3 Entering Other Application Information FIGURE 3.3 Reference this figure for Sections through (below through page 7) Low Flow Cutoff When a zero flow condition occurs, internal sloshing and other fluid movement can prevent the flowmeter from reading total zero. This can result in totalizer errors. Minimize these errors by setting a low flow cutoff which drives the flowmeter to zero for flow rates at or below specified value. Also refer to Section

17 3.3.2 Damping The damping coefficient suppresses short-term fluctuations in the indicated flow rate. Increasing the coefficient increases the response time to changes. Damping should be kept at a minimum unless the flow rate fluctuates wildly. If this is the case with your application, increase the damping just enough to reduce the fluctuation to an acceptable degree. The meter uses a Smart Filter which allows the damping function to smooth small fluctuations without diminishing the meter s response to large flow changes, even at high damping settings Flow Conversion Factor The flow conversion factor is the current conversion factor that adjusts from ft 3 /s to the operator s selected rate, e.g. gal/s. This value is displayed for diagnostic purposes only Velocity Cutoff Velocity cutoff is available for display purposes only when a low flow cutoff is set Site Calibration 1. Determine the flow using another source, and calculate the site calibration adjustment by dividing the actual flow by the meter flow. 2. Click in the text box to the right of Site Cal. and enter the site calibration adjustment Remote Zero This feature enables the meter to read zero flow until signaled by an external control system (e.g., a pump turning on or a valve opening) to begin reading actual flow. This feature is ideal for systems requiring pump-activated flow readings only and not back flow or flow from possible valve leaks. Activate the remote zero feature by selecting On; deactivate the feature by selecting Off. To read flow, open the POSZERO-GND/RELYCOM connection via the external switch. The required switch contacts are usually available in a pump motor controller or valve controller. 7

18 3.4 The Totalizer FIGURE 3.4-A 2.
