2 Application according to designation, general safety instructions Range of application, application according to designation The thermal mass flowmeter FMT400-VTS/-VTCS is designed for flow rate measurements of gas. It is only suit- able to be mounted: • as insertion sensor in a pipe component with flange mounting in pipes of nominal widths from DN 25/1 " to DN 200/8",... -
Page 6: Notes Concerning The Use In Potentially Explosive Areas
Notes concerning the use in potentially explosive areas Only FMT400-VTS is available in a version authorized for use in zone 2 / zone 22. These devices come supplied with an EU declaration of conformity (ATEX). For devices authorized for use in zone 2 / zone 22, only the data and instructions for use stated in the declaration of conformity (ATEX) shall apply. -

• Fasten the flange screws evenly and with the appropriate torque specified for the built-in gasket. • After mounting the pipe components, close the insertion pipe with an appropriate blind flange with gasket, or close the existing stop valve, if applicable. 42/14-36 EN Thermal Mass Flowmeter FMT400-VTS, FMT400-VTCS (Sensyflow VT-S/VT-CS) - Page 8 • Aggressive fluids may cause corrosion or abrasion which may result in leakage of fluids under pressure. • The flange or process gaskets may become leaky due to material fatigue. Media under pressure might escape then. Thermal Mass Flowmeter FMT400-VTS, FMT400-VTCS (Sensyflow VT-S/VT-CS) 42/14-36 EN...

Page 9: Design And Function
Design and function 3 Design and function FMT400-VTS/-VTCS (Sensyflow VT-S/VT-CS) operates on the thermal principle. This measurement method is based on the principle that gas flowing around a heated body absorbs heat from that body.The result of this flow- dependent cooling down process is used as a measurement effect. Since the loss of heat depends on the num- ber of particles reaching the surface of the heated body, it is possible to determine the mass flow directly. -

• When matching up the detecting element with a weld-on adapter, please read the information in chapter 4.6. Please make sure that the units are easily accessible when they are installed. 42/14-36 EN Thermal Mass Flowmeter FMT400-VTS, FMT400-VTCS (Sensyflow VT-S/VT-CS) -
Page 12: Recommended Steadying Run Lengths For Inlet Run Disturbances
The inlet and outlet run lengths are stated as multiples of the pipe diameter D. For combinations of inlet run disturbances, e. g. valve and reducer, you must always consider the longer inlet run length. Thermal Mass Flowmeter FMT400-VTS, FMT400-VTCS (Sensyflow VT-S/VT-CS) 42/14-36 EN... - Page 13 Under certain circumstances, special calibration can be performed for insufficient steadying lengths. For this purpose and in individual cases, consult the DKD Calibration Department of ABB Automation Products GmbH at Alzenau. An on-site adjustment is also possible, if reference flow values are precisely known, by entering a calibration factor.

When working with dusty, abrasive or aggressive measured media, it may be necessary to replace these more frequently. Only ABB Service or qualified personnel of the operator is authorized to replace O-ring gaskets. For the latter case, the warranty is no longer valid for ABB. - Page 23 – Insert the guide tube in the fitting and tighten the 4 hex-head screws of the lock nut until reaching the stop in identical position as with disassembly. – Verify correct installation by rotating the lock nut into measuring and disassembly positions. 42/14-36 EN Thermal Mass Flowmeter FMT400-VTS, FMT400-VTCS (Sensyflow VT-S/VT-CS)
