1. Retrofitting the eddy current brake In connection with the indicator part with EM current output and contactors be aware of the fact that short time movements of the pointer may occur when the eddy current brake is being installed These may possibly generate a false alarm or cause peaking of the current output screw The eddy current brake consists of two parts The brake with retaining ring can clipped on to the pointer cylinder independent of built in components such as EM contacts or totalizers When mounting the brake bear in mind that the slot between the brake magnets measures only approx 3 mm und the aluminium pointer vane has a material thickness of 1 mm Check that the pointer vane can be moved between the magnets without coming into contact with them Slightly turn the eddy current brake clockwise and screw in the clamping screw Adjust the brake as shown on on the right and tighten down the clamping screw Flow totalizer EMZ In combination with the current output EM the flow totalizer MG NZRORRMOK2IESK can also be retrofitted in the indicator part a Civ 25 14871 M 1997 When ordering the totalizer as a retrofit kit please specify ETHYLALKOHOL the device data as shown on the right as well as the o os measuring range These data will enable the new scale E Be with totalizer display cutout to be prepared in readiness FIRC 1121D for installation The flow totalizer is then preset wi2. 13 wa W zw wil a y 6 1 2 Version PTFE ceramics PTFE float Ceramic float Size Water Pressure Water Pressure Air Pressure drop drop drop Wh mbar ih mbar m h iN mbar 15 1 2 25 25 65 3 30 62 4 0 40 66 5 50 64 0 18 1 8 64 6 3 63 66 7 70 66 0 24 2 4 66 10 100 68 13 130 68 0 40 4 0 68 16 160 72 20 200 70 0 65 6 5 70 25 250 86 25 250 72 0 90 9 0 72 40 400 111 25 1 63 630 70 50 500 55 18 18 55 100 1000 80 70 700 60 2 2 22 60 160 1600 108 110 1100 70 3 0 30 70 250 2500 158 160 1600 82 5 0 50 82 250 2500 100 75 75 100 50 2 400 4000 81 450 4500 70 14 140 70 630 6300 110 630 6300 80 20 200 80 1000 10000 170 1100 11000 110 35 350 110 80 3 1600 16000 81 1600 16000 70 2500 25000 95 2500 25000 85 100 4 4000 40000 100 Devices for gas measurement float damping system recommended 1 i N at STP 0 C and 1 013 bar abs 6 2 Materials Version Measuring tube float Temperatur Ambiente 80 C lt 120 C SGM VA SS SS 300 C SGM CA Hastelloy C Hastelloy C nn An SGM PTFE PTFE PTFE 70 C lt 70 C a PIFE _ PTFE ceramics 150 C IE SGM TFM K TFM ceramics 250 C lt 120 C Indicator Scale casing Aluminium enamelled Pointer Aluminium enamelled Scale Aluminium coated Window Float glass 1 Measuring tube of stainless steel 1 4404 with liner A Kirchner amp Tochter GmbH Dieselstra
