284INSERTION batch controller• 15 to 400 mm orifice, compact or remote versionSensors 8025 BType 8025 B can be combined with...Type S020Insertion fittingType 5282Solenoid valveThe Type 8025 B Insertion batch controller is speciallydesigned for use in neutral, slightly aggressive,solid-free liquids.The compact batch controller consists of an electronicmodule and a paddle-wheel sensor with display. Thepaddle-wheel is set into motion by the medium flow,and generates a flow-proportional frequency signal inthe transducer (Hall element), which is converted intovarious output signals in the transmitter electronics.The Bürkert designed Insertion fitting system ensuressimple installation of the sensors into all pipes fromDN15 to 400.The device is available in different models:• Compact batch controller• Remote batch controller for panel or wallmounting for connection to a flow sensor from themarketIn connection with a valve as actuating element, theType 8025 B is able to control with high accuracydosing and filling process. The unit is equipped withtwo totalizers, two relays and three dosing modes. Thetwo output relays are used to activate the valve and toinitiate alarms.The following dosing and filling operations arepossible:• Local dosing using keypad.• Remote control dosing using a rotary knob(selecting a pre-set quantity) or binary data inputs.• Dosing controlled by a PLC unit.• Automatic dosing controlled by a variation of pulseduration.• Dosing unit with 3 different modes(local, binary, time proportional)• Shows actual volume and totalizers• Automatic calibration: TEACH-IN• Simulation: all output signals provided withoutthe need for real flowTechnical dataMeasurement range from 0.2 m 3 /h up to 4500 m 3 /hFlow velocityAccuracy 1)Teach-In (via a remote transmitter)Standard K-factorRepeatability0.3 to 10 m/s≤ ±0.5% o.F.S.* (at 10 m/s)≤ ±(0.5% o.F.S.* + 2.5% o.R.*)≤ 0.4% o.R.*Electrical connection Cable plug DIN EN 175301-803, cable glands M 20x1.5Voltage supply cable Length: max. 50 m, shielded; cross section: max. 1.5 mm 2Protection classRelative humidityFluid temperatureAmbient temperatureStorage temperatureIP 65 with cable plug mounted and tightened≤ 80%, non condensated0 to +50 °C (32 to 122 °F) (fitting in PVC)0 to +80 °C (32 to 176 °F) (fitting in PP, PVDF, brass,stainless steel)0 to +60 °C (32 to 140 °F)0 to +60 °C (32 to 140 °F)Max. fluid pressure PN10 (see pressure-temperature chart, page 295)Viscosity of fluidsFitting body materialOther materialsElectronic housingFront panel folioSensor holder, paddle-wheelAxis and bearingSeal300 cSt. max.PVC, PP, PVDF, stainless steel 1.4404/316L, brassPCPolyesterPVDFCeramics (AL 2O 3)FKM (EPDM on request)Orifice DN 15 to DN 400 (see fitting Type S020, pages 294 to 301)Flow transmitterOperating voltageCurrent consumptionInputOutputDigitalRelayPLC* o.F.S. = of Full Scale (10m/s)o.R. = of Reading12 to 30 V DC; 115/230 V AC - filtered and regulated< 70 mA with relay4 binary inputs, 5... 30 V DCFunctions: dosing quantity choice, start-stop dosingTransistor open collector, NPN/PNP, 0... 30 V DC,100 mA, protected - for status and alarm message2 relays, 3A, 230 VAC, freely programmable1) under reference conditions, i.e. fluid = water, temperatures = 20°C,up and downstream distances respected, adapted dimensions and pipesSubject to modifications
