Default Universal Setting A fromBank 1 is recommended for most low flow sampling gas or liquid service. Gas and liquid service applications where higher flow rate detectionis required may select Universal Setting B from Bank 3.Scaling is performed in the following order:Minimum Flow Setting (Function 6)Select function 6 to capture the minimum flow rate. In liquids, optimum performance is achieved by setting the Minimum Flow to a full line atno flow. If possible, with liquids, slightly pressurize the pipe and block the flow using valves to assure a full and static condition. Capturing theno-flow value in Function 6 establishes the zero point.Maximum Flow Setting (Function 7)Run the process at maximum flow and use this function to capture the maximum flow in gas or liquid. Since liquids transfer heat very ef-ficiently, depending on the sensor assembly and fluid, maximum signal level will likely be achieved at flow rates under 2 feet per second,though the actual flow in the tube may be higher. Capturing the maximum flow effectively establishes the span in the installation.Note: Be sure to pause at least 30 seconds before capturing zero and span to assure unit has reached equilibrium.Switch Point Adjust (Function 1 or 2)There are two ways to set the switch point using the buttons.Function 1 uses the LEDs as indicators to set the switch point in 10% increments within the established span.Function 2 may be used to set the precise switch point by “capturing” the exact process flow rate. In liquids, make certain the desiredswitch point is within the set operating range. That is, when capturing at the switch point, the LEDs should be showing no greater than90% flow. Note: The switch point setting is saved in feet/sec; therefore, changing the span later may alter the relative position of the flash-ing LED indicating the switch point value.Low flow alarm applications with relay energized above the switch point (default setting): The switch point LED flashes quickly when the flowis below the switch point. The LED flashes at a slower rate when the flow is at or above the switch point. |
