Installing / Disassembling Pipe Components; Installing / Disassembling The Flowmeter Sensor; Target Groups And Qualifications - ABB Sensyflow FMT400-VTS Commissioning Instructions

1.2.2

Installing / Disassembling pipe components

• During installation, it is important to ensure that the flow direction corresponds to the
attached 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 of
the mounting flange's sealing surface.
• In the case of flanged connections, flat gaskets must be installed. These must be in perfect
condition and resistant to the measuring media.
• Before installing pipe components or flowmeter sensors, check all components and gaskets
for damage.
• Pipe components must not be installed under tension, otherwise the pipeline may be
subjected to impermissible forces.
• When assembling the flanged connections, use screws that offer the required strength and
dimensions.
• The screws must be tightened evenly and to the required torque.
• Once the pipe components have been installed, the insertion connection must be sealed by
means 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 sensor
data matches the measuring point specifications.
• It is very important to use the O-ring supplied (not a flat gasket). This is resistant to
measuring media and should be inserted in the groove provided in the pipe component
flange.
• Take care not to damage the measuring elements when inserting the flowmeter sensor into
the pipe component, as this is not permitted.
• The flowmeter sensor should be firmly bolted together with the flange of the insertion
connection. 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 fitting
is in the disassembly position before releasing the mounting screws.

Target groups and qualifications

Installation, commissioning, and maintenance of the product may only be performed by trained
specialist personnel who have been authorized by the plant operator to do so. The specialist
personnel must have read and understood the manual and comply with its instructions.
Prior to using corrosive and abrasive materials for measurement purposes, the operator must
check the level of resistance of all parts coming into contact with the materials to be measured.
ABB Automation Products GmbH will gladly support you in selecting the materials, but cannot
accept any liability in doing so.
The operators must strictly observe the applicable national regulations with regards to
installation, function tests, repairs, and maintenance of electrical products.
