13 Page 138 Meters Without Straightening Vanes: Install at least 10 times the diameter downstream from butterfly valves, elbows, cooling coils, tees, reducers, increasers, & other obstructions. With Straightening Vanes: Install at least 5 times the diameter downstream from butterfly valves, elbows, cooling coils, tees, reducers, increasers, & other obstructions. Jetting Flows: Check, Chemigation, and Combo valves create jetting flows inside the pipe that require a straightening vane and meter installation 10 times the diameter down stream from the valve. Reverse Impeller Meters: Reverse Impeller Meters require Bolton Vanes which allows for the passage of grass, debris and other solids. Upstream requirements are the same as listed above. The center of the meter hole has to be two pipe diameters from the end of the pipe to the end of the impeller, plus 16 inches. Example: ( Pipe x 2 diameters = 20") +1 = 3 from end of pipe to center of the meter hole.

Flow straightener is a coneshaped device that sits upstream from the meter and conditions the fluid to remove flow irregularities prior to measurement. The conditioned flow supports high accuracy flow measurement and virtually eliminates the need for spaceconsuming, costly upstream/downstream straightpipe runs Schumacher Irrigation, Inc.
