Insulation is allowed up to thefirst flange of each transducer.The connection box and the flanged transducers require adequate cooling by ambient air andmust be protected against heat radiation by surrounding equipment.3.2.4 Pipe flangesFigure 3-9: Approved insulations.1 Building construction "single beam" (DN25...40)2 Building construction "single beam" (DN50...80)3 Building construction "dual beam" (≥DN100)Refer to dimensional drawings for flange spacing and in addition allowance for thickness ofgaskets.Figure 3-10: Maximum deviation between flanges1 L max2 L minMax. permissible deviation of pipe flange faces:L max - L min ≤ 0.5 mm / 0.02"16www.krohne.com02/2010 - 4000210602 - TD UFM 530 HT R02 en
UFM 530 HTINSTALLATION 33.2.5 Pipes with cathodic protectionPipes with electric corrosion protection are generally insulated inside and outside so that thefluid has no conductive connection to the ground. The flow meter must be insulated from thepipe. Observe the following instructions when installing the flow meter:• The pipe flanges must be connected to each other using a copper cable (L), but must not beconnected to the flowmeter.• The bolts for the flange connections and the gaskets must be insulated. Use sleeves andwashers that are made of insulating material (these must be provided by customer).Figure 3-11: Cathodic protection1 Flanges (left one: of flow sensor, right one: of pipe)2 Nut3 Washer4 Insulating sleeve5 Bolt6 Gasket02/2010 - 4000210602 - TD UFM 530 HT R02 enwww.krohne.com17
