SafetyCI/FMT500-IG-EN Sensyflow FMT500-IG EN - 71.2.2 Installing / Disassembling pipe components• During installation, it is important to ensure that the flow direction corresponds to theattached label.• When welding the weld-on adapter, remember to observe the relevant welding instructions.The amount of heat introduced must be kept to an absolute minimum to prevent warping ofthe mounting flange's sealing surface.• In the case of flanged connections, flat gaskets must be installed. These must be in perfectcondition and resistant to the measuring media.• Before installing pipe components or flowmeter sensors, check all components and gasketsfor damage.• Pipe components must not be installed under tension, otherwise the pipeline may besubjected to impermissible forces.• When assembling the flanged connections, use screws that offer the required strength anddimensions.• The screws must be tightened evenly and to the required torque.• Once the pipe components have been installed, the insertion connection must be sealed bymeans of a blind flange plus gasket or by closing a shut-off device (if present).1.2.3 Installing / Disassembling the flowmeter sensor• Installation in the pipe component or weld-on adapter is only possible if the flowmeter sensordata matches the measuring point specifications.• It is very important to use the O-ring supplied (not a flat gasket). This is resistant tomeasuring media and should be inserted in the groove provided in the pipe componentflange.• Take care not to damage the measuring elements when inserting the flowmeter sensor intothe pipe component, as this is not permitted.• The flowmeter sensor should be firmly bolted together with the flange of the insertionconnection. The screws must be tightened evenly to the required torque.• Torque for screws supplied: 87 Nm (unlubricated, without using spring washers).• If you are using a pipe component with a hot tap fitting, you must check that the hot tap fittingis in the disassembly position before releasing the mounting screws.1.3 Target groups and qualificationsInstallation, commissioning, and maintenance of the product may only be performed by trainedspecialist personnel who have been authorized by the plant operator to do so. The specialistpersonnel must have read and understood the manual and comply with its instructions.Prior to using corrosive and abrasive measurement media, the operator must check the level ofresistance of all parts coming into contact with the wetted parts. ABB Automation ProductsGmbH will gladly support you in selecting the materials, but cannot accept any liability in doingso.The operators must strictly observe the applicable national regulations with regards toinstallation, function tests, repairs, and maintenance of electrical products.
