SU0246.DOC 05/04 Änderungen vorbehalten!Operating InstructionsGNR5C Sight-Glass Level ControllerFigure. 1: GNR5C with threaded connectors and 2BSM500W_/d34 bistable switchesAttention!• Use with low-viscosity media only whichneither tend to become sticky or encrusted,nor precipitate crystals. Media may notcontain magnetic particles (e.g. metal chips).• Use only type S5/25d floats.• The float must be installed with the “TOP”marking at the top.• Observe maximum temperature and pressureratings.• Do not allow to tilt during installation! Centre-to-centre distance and squareness of theflanges or threaded connectors should bechecked before installing the glass tube.• Observe correct installation order for sealingrings (see drawing next page).Functional Principle:The GNR5C sight-glass level controller is mounted to theside of a vessel or a tank. The gauge is filled with liquidmedia to the same level as the tank via two shut-offvalves.A magnetic float is located within the standpipe, whichindicates the current fill-level.The glass tube is protected against damage with asemicircular impact guard made of transparent PVC.The magnetic float can also be used to activate optionallyavailable BSM 500 W... bistable switches (see also datasheet SU0090).Technical DataStandpipe Glass, DURAN. 34.5 x 2.75 mmFloat Polypropylene (PP), type S5/25dFittings Stainless steel 1.4404/316L withEPDM sealingSeals Silicon rubberOperating temperature 0 to + 110° C (120° C intermittent)Operating overpressure max. 1 barLength (flange centre-to-centre)300 to 2000 mmMounting Flange: DIN 2642 DN 25 PN, steelalternatively DN20 PN10 steelorthreaded connector: G½" or G1"Discharge stopcock(optional)stainless steel 1.4404Electrical components BSM 500 W... bistable switchwith 34 mm dia. pipe clampInstallation Procedure:GNR5C with Flanges:• Mount the top and bottom shut-off valves to the tankflanges using suitable sealing materials. Do not yetfully tighten the screws.• Insert the 11 x 12 x 5 mm silicon discs into the shut-offvalves.• Push the hose clamps for fastening the impact guardand the sleeve nuts, along with the silicon rings (whichhave been snapped into place inside the nuts), overthe standpipe (see figure 2).• Insert the standpipe between the shut-off valvesmaking sure that is square.• Check the length of the glass tube! The tube must fitflush against the silicon discs. Loosen the flangescrews if necessary to correct distance andsquareness.• Retighten the flange screws.• Push the sleeve nuts up to the shut-off valves andtighten (46 mm open-end wrench).Tighten the sleeve nuts!• Attach BSM 500 W… bistable switches if used (thecable gland must always point down).• Mount the transparent impact guard (see figure 2).• After the vessel has been filled, check all fittings forleaks! |
