Safety notes2.2 Installation in hazardous areaWARNINGPotential equalizationIn operation, the output is earthed through the conductive medium being measured andtherefore potential equalisation is necessary throughout the hazardous area.The apparatus housing shall be connected to the potential equalising conductor in thehazardous area.WARNINGExternal connections to Ex e terminalsThe external connections to the Ex 'e' Terminals of the Remote version shall complywith the following: The wire conductors shall have a cross-sectional area between 0.5 mm2 and 2.5mm2. No more than one single or multiple strand wire conductor shall normally beconnected to each of the terminals. If multiple conductors are required, these shall bejoined in a suitable manner, e.g. two conductors into a single insulated crimped bootlace ferrule. The insulation on the wire conductors shall extend to within 1mm of the metal of theterminal throat. The terminal screws shall be tightened down with a torque between 0.5 Nm and 0.7Nm. The terminals shall never be exposed to temperatures outside of the range -50 C to 130 C; in addition, they shall only be installed and wired with cable in an ambienttemperature of -10 to 80 C. Furthermore, in the event of there being a processtemperatures of 180 C in conjunction with an upper ambient temperature of 50 Cthe terminal strips should not be installed or wired with cable.WARNINGExplosive gas or dustThe terminal box shall not be opened when an explosive gas or dust atmosphere maybe present.WARNINGDo NOT open the device while energized; otherwise there is a risk of explosion.WARNINGLaying of cablesCable for use in zone 1 and 2 or 21 and 22 must satisfy the requirements for having aproof voltage AC 500 V applied between the conductor/ground, conductor/shield andshield/ground.Connect the devices that are operated in hazardous areas as per the stipulationsapplicable in the country of operation, e.g. for Ex "d" and "nA", permanent cables mustbe laid.SITRANS F M MAG 3100 sensor14Operating Instructions, 09/2012, A5E03005599-02

MODBUS RTU RS 485, PROFIBUS PA / DP and Devicenet, are all applicable withthe SITRANS F M MAG 6000 transmitter.SITRANS F M MAG 3100 sensorOperating Instructions, 09/2012, A5E03005599-0217
Description3.2 Design3.2DesignSITRANS F M MAG 3100 is available in a wide range of sizes (DN 15 to DN 2000 (½" to78")) and pressure ratings (PN 6 to PN 100 / ANSI Class 150 / 300, AS 2129 / AS 4087. Onrequest up to 690 bar (10 000 psi)) The fully welded construction provides a ruggedness thatsuits the toughest applications and environments.Sensor housing and flanges are designed in carbon steel (ASTM A 105) and terminal box infibre glass reinforced polyamide or optionally in stainless steel (AISI 316). Measuring pipe ismade of stainless steel (AISI 304) while liners and electrodes are available in variousmaterial, which makes the sensor highly resistant to a wide range of chemicals.The present range of liner types includes: PTFE PFA Soft rubber EPDM Linatex Ebonite Hard RubberElectrodes are available in: Hastelloy C276 or C22 AISI 316Ti (1.4571) Platinum / Iridium Titanium TantalumThe sensors carry a wide range of approvals, see Technical data (Page 47).SITRANS F M MAG 3100 sensor18Operating Instructions, 09/2012, A5E03005599-02
Description3.3 Theory of operation3.3Theory of operationThe flow measuring principle is based on Faraday’s law of electromagnetic induction.0DJQHWLF )LHOG)ORZUi When an electrical conductor of length L is moved at velocity v, perpendicular to thelines of flux through a magnetic field of strength B, the voltage Ui is induced at the ends ofthe conductorUi L x B x v Ui Induced voltage L Conductor length Inner pipe diameter k1 B Magnetic field strength k2 v Velocity of conductor (media) k k 1 x k2Ui k x v, the electrode signal is directly proportional to the fluid velocityOperating principleThe coil current module generates a pulsating magnetizing current that drives the coils in thesensor. The current is permanently monitored and corrected. Errors or cable faults areregistered by the self-monitoring circuit.The input circuit amplifies the flow-proportional induced voltage signal from the electrodes.The input impedance is extremely high: 1014 Ω which allows flow measurements on fluidswith conductivities as low as 5 µS/cm. Measuring errors due to cable capacitance areeliminated due to active cable screening.The digital signal processor converts the analog flow signal to a digital signal andsuppresses electrode noise through a digital filter. Inaccuracies in the transmitter as a resultof long-term drift and temperature drift are monitored and continuously compensated for viathe self-monitoring circuit. The analog to digital conversion takes place in an ultra low noiseASIC with 23 bit signal resolution. This has eliminated the need for range switching. Thedynamic range of the transmitter is therefore unsurpassed with a turn down ratio of minimum3000:1.SITRANS F M MAG 3100 sensorOperating Instructions, 09/2012, A5E03005599-0219

Installing/Mounting4SITRANS F flowmeters with minimum IP65/NEMA 4X enclosure rating are suitable for indoorand outdoor installations. Make sure that pressure and temperature specifications indicated on the devicenameplate / label will not be exceeded.WARNINGInstallation in hazardous locationSpecial requirements apply to the location and interconnection of sensor and transmitter.See "Installation in hazardous area" (Page 11)4.1Installation safety precautionsWARNINGHigh pressure hazardIn applications with working pressures/media that can be dangerous to people,surroundings, equipment or others in case of pipe fracture, we recommend that specialprecautions such as special placement, shielding or installation of a pressure guard or asafety valve are taken when the sensor is mounted.4.2Determining a locationNoteThe sensor must always be completely filled with liquid.Figure 4-1Correct installation with filled pipesSITRANS F M MAG 3100 sensorOperating Instructions, 09/2012, A5E03005599-0221
