2. Field Installation Option Description Downstream Use this option when the sensor is installed downstream of the measurement point where the flow stream exits the site This option is useful when more than one flow stream enters a site and the combined flow of all streams at a single exit point is measured Mount the sensor in the downstream direction rather than the typical upstream direction Mounting the sensor backwards in this manner Figure 15 causes the velocity direction readings to be the opposite of actual stream flow By selecting the Downstream choice when programming the logger reverses the measured signal to show actual flow direction beveled edge downstream The maximum velocity obtained in this type of installation is 5 fps 1 Additional options may be available depending on the flow meter or sampler used Refer to the appropriate flow meter or sampler manual for more information 4 5 8 Performing a Level Adjustment The manufacturer recommends doing a level adjustment whenever a sensor is first installed into a flow stream This adjustment accounts for the various physical tolerance stack ups in the system i e thickness of the mounting band angular placement of the sensor relative to the 6 O clock position in the pipe etc 1 With the sensor installed in the flow use a PC or display 950 and 980 flowmeter to monitor Current Status 2 Take a physical measurement of the
