5 _- = <br />Pipe fittings <br />Georg Fischer offers a wide selection of installation fittings that control the position of the Magmeter electrodes in relation to the <br />dimensions of the pipe. You will find a complete list of order numbers for installation fittings in the Calibration Tables on pages 8, 9. <br />Description <br />Plastic <br />tees -t - ® <br />0.5 to 2 inch versions <br />-1!11_J <br />MPVC or CPVC <br />PVC <br />Available in 10 and 12 inch sizes only <br />Glue -on (' <br />Cut 2-1/2 inch hole in pipe <br />Saddles ice' <br />Weld in place using solvent cement <br />PVC <br />Clamp -on <br />Saddles <br />Type Description <br />Iron, Carbon Steel, <br />316 SS 0.5 to 2 in. versions <br />Threaded tees F7n Mounts on threaded pipe ends <br />Carbon steel & <br />stainless steel 2 to 4 inch, cut 1-7/16 inch hole in pipe <br />Weldon Over inch, cut 2-1/8 inch hole in pipe <br />Weldolets <br />2 to 4 inch, cut 1-7/16 inch hole in pipe Fiberglass <br />6 to 8 inch, cut 2-1/8 inch hole in pipe tees <br />Iron 2 to 4 inch, cut 1-7/16 inch hole in pipe <br />Strap on Over 4 inch, cut 2-1/8 inch hole in pipe <br />saddles ���� Special order 14 in. to 36 in. <br />�] I • 1.5 in. to 2 in.

Th? 3 prevents condensation inside the cnnduit from being directed <br />into the 2551 electronics housing. <br />• Chemical injection systems can temporarily alter the fluid conductivity and <br />cause anomalies in the magmeter measurement. <br />• To avoid this problem, install the magmeter UPSTREAM of the injection point. <br />Injection Point 9900 <br />2551 <br />9900 Injection Point <br />2551 <br />Reducer.
