Fantini Cosmi Liquid flow controller FF82

3G-CBM-03595 FLOW SWITCHES FF82 FOR PIPES FROM G1 TO G8 GENERAL CHARACTERISTICS 110 65 Flow switches are suitable to control and adjust air in conditioning. It acts in compliance with the technical regulations of the M.D. 1/12/1975 (Safety) standards for the instruments containing hot liquids under pressure) and with the collection R file R.2.C.6. Into heating plants with closed expansion tank where the circulation is guaranteed by electropumps, the heat supply must be automatically interrupted in case of stop of the circulation pumps. 65,5 Flow INSTALLATION To be installed on sections of horizontal pipe, far from valves, elbows, 132 irregular flows or discharges,the straight pipe must be at least 5 times of the long of the of the pipe. The flow direction must follow the arrow designed on the instrument. -Respect installation distance as per ( fig 1) - Check the correct installation and the correct functioning, pushing the regulation screw to simulate flow ( fig 2) CH 38 Flow 25 28 (Fig.1) 35 Max.48 Flow regulation screw 58 (Fig.2) 89 167 ELECTRICAL FEATURE SPDT microswitch TECHNICAL CHARACTERISTICS Nominal tension: 250Vac -Flow rate as per table Continous duty nominal current: 16 (6) A -Protection gade Ip65 -Max pressure 10 bars According to CEI EN 60947-5-1 -Working temperature: -20 ÷110°C CEI EN 60529 -Ambient temperature: 50°C Flow increases: open C-NC -Antishock thermoplastic material enclosure Close C-NO -Paddles in inox AISI 301for pipes from G1 to G8 -G1” connection CALIBRATION -Female 6,3mm electrical connection Device is supplied with lower flow rate calibration; -Sealed cable glande Pg16 To modify it use use regulation screw as per fig 3 (Fig.3) PIPELINE PADDLE Minimum flow rate Maximum flow rate DIAMETER Value m3/h Value m3/h TYPE mm Decreasing Increasing Decreasing Increasing 1” 35 0,5 1 1,9 2 1” ¼ 35 0,7 1,2 2,7 2,9 1” ½ 58 1 1,6 3,6 3,9 2” 58 2,1 2,9 5,7 6,1 2” ½ 89 2,7 4 6,5 7 3” 89 4,3 6,1 10,7 11,4 FF82 89 11,3 14,7 27,6 28,9 4” * 167 6,1 7,9 17,3 18,4 89 22,8 28,3 53 55,5 5” * 167 9,2 12,8 25 26,7 89 35,8 43 81,6 85 6” 167 12,2 16,8 30,5 32,5 * 72,4 85 165,5 172,3 89 8” 167 38,5 46,4 90,7 94 * *values using longer paddle WE RESERVE THE RIGHT TO MAKE ANY NECESSARY TECHNICAL MODIFICATIONS WITHOUT ADVANCED NOTICE 2005/03
