INSTALLATION DISTORTED FLOWS A PVC fitting is usually installed by solvent welding. The stainless steel and brass meter fittings have female pipe threads,i requiring the appropriate male threaded fittings. Faster Flow Saddle fittings(size 3" and above) require a hole to be cut Causes Meter in the pipe. The recommended hole size is 1-3/4". Distorted To Read High Flow Profile Meter Installation. After the meter fitting is installed in i � the pipeline, the meter can be installed in the fitting. After i noting the direction of the flow arrow, press the meter into the fitting as far as it will go. Retain the meter in place by r inserting the u-pin. The pin can be installed from either FLOW side. It may be necessary to rotate the probe back and 14X 5X forth slightly to start the pin into the slots on the probe.

EX80 Series meters require spe- no air in the pipe cial fittings. The meter fitting must first be installed in the pipeline. Straight pipe of at least ten times the diameter upstream of the meter and five diameters downstream is ! strongly recommended in order to achieve proper accu- racy. These are minimum values. As the diagrams on the the next page will show,you may need much more straight 4 run under specific adverse circumstances. E t BEST POSITIONS If you can't provide enough run to smooth out the turbu- lence caused by valves, fittings, and changes in direction, ' some decrease in accuracy may result. This does not mean that the flow meter's reading is meaningless, how- �k ever. In some applications, a repeatable reading may be r more important than a highly accurate one. In applica- tions where the flow meter is part of a control system, operating a valve or controlling chemical addition, repeat- ability of reading is more critical than absolute accuracy. EX80 Series PVC meter tees are supplied with some up Caution: Never remove the u-clip stream straight pipe. The length provided may be less retainer when the pipe is under pressure. than ten diameters upstream and five downstream. It is Always remove pressure from the pipe not advisable to connect directly to the end of these before you attempt to remove the meter. Removal 4 fittings with a flow-disturbing device such as a valve or under pressure may result in damage or serious elbow. If possible, straight pipe should be added to the injury.. i upstream end of these fittings. ` t f Page 2 {
