The signal output is suppliedexclusively in a two-wire connection at 4-20 mA. Normally,the 4-20 mA signal has the HART® protocol; alternatively itcan have PROFIBUS PA.Additional options: 2 limit values, alternatively 1 limit valueand 1 pulse outputThe signal output and the limit values can be configuredusing a HART® modem operating on the followingconfiguration programs: SensorPort from Bopp & Reuther,PDM from Siemens or AMS from Rosemount. Furthermore,a HART® hand-held terminal (with DD software) can also beused. For more information about configuration, please referto the separate Operating Instructions for the ES.Safety class: DMT 00 ATEX 075 / II2G EEx ia IIC T6When installing electrical equipment in hazardous areas,the conditions and provisions specified in the approvaldocmuments must be followed.5.3 Analog output with the KINAX 3W2angle-of-rotation transmitterThe signal output of the angle-of-rotation transmitter isfactory-calibrated to the scale values. The signal output is 4-20 mA in 2-wire connection; or alternatively 0-20 mA in 4- or3-wire connection. The signal output of 4 mA corresponds tothe flow rate scale value of 0 (0 mA for the 0-20 mA version).5.6 mA corresponds to 10% of the flow rate scale value(2 mA). 20 mA corresponds to 100% of the flow rate scalevalue.Use in hazardous areas:The angle-of-rotation transmitter is a component approvedfor hazardous areas. When used in hazardous areas, all thevalues and instructions indicated in the certificate of approvalmust be observed. Auxiliary power is fed through anapproved intrinsically safe circuit of 12-30 V. To proveintrinsic safety, only authorized electrical equipment may beinterconnected. Please take note of the maximumpermissible ambient temperature of 60°C/75°C for thetransmitter and the process temperature.Safety class:PTB 97 ATEX 2271 / II 2G EEx ia IIC T66 Characteristic values6.1 Measuring accuracy6.1.1 Reference conditionsWater 20°C6.1.2 Measured error(for liquids)BGN-S/H/P +/- 1.6% of URV for local display(URV = upper-range value)(for gases)BGN-S/H/P +/- 2.0% of URV for local displayAdditional inaccuracy for:ES = +/- 0.2%KINAX 3W2 = +/- 0.5%6.1.3 Repeatability+/- 0.5 % of upper-range value6.2 Influence of ambient temperature1.

With ES transmitter:+/- 0.5 % / 10 K reference temperature 22°C6.3 Influence of fluid temperatureDeviations in fluid temperature from the temperatureobserved during calibration can result in a proportionaldisplay fault because of the corresponding change indensity. Changes in viscosity cause a non-linear displayfault.7 Conditions of useThe VDI/VDE guidelines 3513, Sheet 3, must be observed.The meter is suitable for :1) Liquids with sufficient flowability that are free ofsolids, do not bond and do not tend to settle.2) Gases with linear flow behavior and an adequateinlet pressure.7.1 Mounting requirementsThe mounting location must be suitable for a verticaldirection of flow from the bottom to the top.Important: If that is impossible, then the device type BGFmay be utilized. This device can be used for both horizontaland vertical direction of flow.Page 6 of 30

Heinrichs MesstechnikThe limit values for temperature and air humidity at themounting location must be maintained. Avoid corrosiveatmospheres. If this cannot be avoided, ventilation must beinstalled.Please make sure that there is adequate clearance fromparts that might cause magnetic interferences such assolenoid valves and ferromagnetic components like steelbrackets/supports. We recommend that the minimum lateraldistance between two adjacently mounted devices be300 mm. The devices can be mounted close together ifvertically offset by one device length. The minimum lateralclearance for interfering steel parts should be 200 mm. Incase of doubt, check the interference by moving the deviceback and forth in the selected distance by about 200 mmand testing whether the pointer position changes.Select the mounting location so as to enable a reliablereading of the scale values. Please take note as well of thespace requirement for any possible disassembly of thedevice. As a rule, inlet and outlet sections in front of andbehind the device are unnecessary if the medium has alinear flow profile. Avoid mounting accessories convergingon one side in front of the device. However, if this isindispensable maintain a minimum device length of 250 mmas an inlet section.The nominal size of the pipes to be connected mustcorrespond to that of the meter. Avoid fittings converging onone side directly in front of the device. As a rule, installvalves behind the measuring equipment if there are gasesinvolved.7.1.1 Mounting/start-upThe device must be mounted in accordance with thedirection of flow from the bottom to the top (perpendicularly).Please observe the prior reference to the BGF-type device.BGN Installation and Operating InstructionsIf there is risk of dirt or solid matter penetrating the processpipes, flush them beforehand so that these materials do notget caught in the device. Ferromagnetic solid matter suchas spatter can lead to the breakdown of the device. If thesematerials are still present during normal operatingconditions, mount a magnetic filter (accessory) in front of thedevice. When using liquids, flush to avoid a surge of gasbubbles. Slowly increase the supply pressure when usinggases to prevent pressure surges. Basically, avoidactivation using solenoid valves to prevent the float fromshooting upwards.7.1.1.1 Gas measurementWhen using gases, slowly let the operating pressure rise. Atthe same time, vary the operating pressure through a settingvalve so that the float is not knocked around since otherwisethis would damage the measuring element.7.1.2 Device settingsThe measuring equipment is delivered ready for operationaccording to your order specifications. The limittransducers are set to the desired values. If you havesubmitted no requirements, the basic setting for1 contact device: - Minimum contact switching point at 10%of descending flow (damped/closed-circuit principle).2 contact devices: Minimum contact switching point at 10%of descending flow and maximum contact switching point at90% of ascending flow.7.1.3 Adjusting the limit transducerThe contacts are adjustable through the contact positionindicators located on the scale. Dismantle the indicatorcover, unfasten the contact position indicators, set to thedesired value and reattach them.The nominal size of the device and that of the pipes must bethe same. The pressure stages and, hence, the dimensionsof the flanges must coincide. The surface roughness of theflange sealing surface must be suitable for the prescribedgaskets.Please check whether possible accessories like springstops, gas/liquid-type dampers are still correctly sitting on theflange. Check whether the mounting clearance between theflanges of the pipes corresponds to the assembly dimensionof the device plus two gaskets. To achieve stress-freemounting, the flanges of the pipes must be aligned parallel toeach other.Use connecting bolts and gaskets in the prescribeddimensions. The gaskets must be suitable for the operatingpressure, the temperature and the measured medium. WithPTFE-coated devices, use gaskets whose interior andexterior diameter correspond to the sealing strip of thedevice.Tighten the screws crosswise so that the processconnections are tight. See to the tightening torques ofscrews especially with PTFE-coated devices.The maximum torques for PTFE-coated devices are:DN15/DN25 = 14 Nm/DN50 = 25 Nm/DN80 = 35 Nm/DN100= 42 Nm (following VDI/VDE Guideline 3513).Please check whether the pipe is adequately stable to ruleout the possibility of vibration or swinging of the device. (Donot use steel mounting parts on the device.)When gas is used as the medium, pay special attention tothe position of the valve. If the device is calibrated to morethan 1.013 bars absolute pressure, the valve is usuallyinstalled behind the flowmeter. At 1.013 bars absolutepressure (free exhaust) install it in front of the device.Page 7 of 30

Heinrichs MesstechnikBGN Installation and Operating Instructions7.1.4 Operation in hazardous areas7.1.4.1 Without electrical equipmentThe basic version of the flowmeter is a non-electrical devicewithout its own ignition sources and meets DIN EN 13463-1requirements. It can be used in hazardous areas thatrequire Category 2 equipment.Marking:II 2GD cReg. No.: BVS 03 ATEX H/B 112Tech. File Ref. 03-02 XSince the device does not have its own power sources thatwould result in a temperature increase, the fluid temperatureis decisive for the maximum surface temperature.When used in potentially explosive dust atmospheres, thedevice must be cleaned regularly in order to avoid depositsexceeding 5 mm.7.1.4.2 With built-in electrical limit transducersWhen the limit transducers are installed, the device becomesan electrical assembly and receives a marking in accordancewith DIN EN 50014 from the entire device with the built-inelectrical limit transducers.The electrical and thermal data and the special conditions ofthe EC Type Examination Certificate of the built-in limittransducers must be observed (see also the diagram inSection 7.3.2).The influence of the fluid temperature on the built-in limittransducers must be observed. The overtemperature of themaximum fluid temperature based on the maximum ambienttemperature must be considered with a factor according tothe following table:Nominal sizeFactor forstandardversionDN15 and DN25 0.2 0.07DN40 and DN50 0.25 0.085DN80 and DN100 0.3 0.1Example for built-in limit transducer forDN 15 and DN 25:Max. ambient temperature T amb = 40°CMax. fluid temperature T m = 120°CFactor for brought-in heat F = 0.2Temperature classT4T ü =T a =OvertemperatureAmbient temperature oflimit transducerTü = Tm −Tamb= 120 ° C − 40°C = 80°CTa = Tü * F + Tamb = 80°C *0,2 + 40°C = 56°CFactor for thedevice with theindicator pulledforwardIn accordance with the tables in thePTB 99 ATEX 2219 X EC Type Examination Certificate, theSJ 3,5-...

Beforeinstalling the device, clean the pipes of dirt, spatter and otherforeign matter. If the medium comes with solid particles,connect a suitable filter in series. When dealing with flowmedia with ferrous particles, we recommend the connectionof a magnetic filter.To protect both magnetic filter types, MF-S (stainless steel)and MF-P/S (PTFE/stainless steel), from corrosion,encapsulated permanent magnets are laid out in spiral form.The spiral mounting produces optimum effect at smallpressure loss. The filter can be supplied with groove ortongue, projection or return, other standards or specialconnections according to customer wishes.Dimensions:DNg (mm)15 4525 6840 8850 10265 12280 138100 158Page 13 of 30
