61. o Open Channel Flow Measurement Handbook provides much useful information in this regard If you want to measure flow using a gravity flow equation such as the Manning equation you will generally install the probe in the entrance upstream pipe of a manhole If you want to measure flow by calibrating a manhole invert you would probably locate the probe directly in the manhole invert In any case you must determine the appropriate location of the probe based on the hydraulic characteristics of the site and the method of level to flow rate conversion used You do not have to install the submerged probe at the bottom of the flow stream Although the bottom is the normal position the Parameter to Adjust step in the program allows you to mount the probe at any vertical location in the stream and then adjust the indicated level to match the actual level The flow meter can indicate negative levels A location other than the bottom of the flow stream may be useful for various reasons to avoid heavy concentrations of silt sand or other solids to make installation easier in tight loca tions to maximize level resolution over a specific level range to avoid hydraulic obstructions in the flow stream etc 4120 Flow Logger Section 2 Installation The probe has several ports through which liquid enters the body to contact the pressure transducer The only way for the probe to malfunction is for all the ports to be completely blocked Mos
