INSTALLATION <br /> i <br /> E <br /> DISTORTED FLOWS A PVC fitting is usually installed by solvent welding. The <br /> r stainless steel and brass meter fittings have female pipe <br /> threads,;requiring the appropriate male threaded fittings. <br /> I Faster Flow Saddle fittings(size 3" and above) require a hole to be cut <br /> 4". <br /> in the pipe. The recommended hole size is 1-3 <br />� Causes Meter / <br /> t Distorted To'Read High <br /> r-, Flow Profile Meter Installation. After the meter fitting is installed in <br /> . the pipeline,the meter can be installed in the fitting. After <br /> noting the direction of the flow arrow, press the meter into <br /> the fitting as far as it will go. Retain the meter in place by <br /> inserting the u-pin. The pin can be installed from either <br /> FLOW <br /> side. It may be necessary to rotate the probe back and <br /> AOX 5X forth slightly to start the pin into the slots on the probe. <br /> Diameter Minimum Diameter Minimum <br /> See Below) Slide the pin in as far as it will go. <br /> See Below <br /> f <br /> k POSITIONING THE METER <br /> Okay position if there is <br /> Fitting Installation. EX80 Series meters require spe- no air in the pipe <br /> cial fittings. The meter fitting must first be installed in the <br /> pipeline. Straight pipe of at least ten times the diameter <br /> upstream of the meter and five diameters downstream is <br /> strongly recommended in order to achieve proper accu- <br /> racy. These are minimum values. As the diagrams on the <br /> the next page will show,you may need much more straight <br /> run under specific adverse circumstances. <br /> BEST POSITIONS <br /> If you can't provide enough run to smooth out the turbu- <br /> lence caused by valves, fittings, and changes in direction, <br /> some decrease in accuracy may result. This does not <br /> - mean that the flow meter's reading is meaningless, how- <br /> ever. In some applications, a repeatable reading may be <br /> more important than a highly accurate one. In applica- <br /> tions where the flow meter is part of a control system, <br /> ` operating a valve or controlling chemical addition, repeat- <br /> ability of reading is more critical than absolute accuracy. <br /> EX80 Series PVC meter tees are supplied with some up Caution: Never remove the u-clip <br /> C t p <br /> stream straight pipe. The length provided may be less retainer when the pipe is under pressure. <br /> than ten diameters upstream and five downstream. It is 4fyAlways remove pressure from the pipe <br /> not advisable to connect directly to the end of these before you attempt to remove the meter. Removal <br /> fittings with a flow-disturbing device such as a valve or under pressure may result in damage or serious <br /> injury, <br /> elbow. If possible, straight pipe should be added to the. <br /> upstream end of these fittings. <br /> Page 2 <br />
