280INSERTION flow transmitter• 15 to 400 mm orifice, compact or remoteversionSensors 8025 TType 8025 T can be combined with...Type S020Insertion fittingType 2712Globe control valveThe Type 8025 Insertion flow transmitter is speciallydesigned for use in neutral, slightly aggressive, solidfreeliquids.The compact transmitter 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 (Coil element for the battery version orHall element for others), which is converted into variousoutput 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 transmitter.• Remote universal transmitter for panel or wallmounting for connection to any flow sensor.• Remote transmitter for panel or wall mounting forconnection to the Bürkert 8020/8030 sensors.The transmitter provides standard or pulsed outputsignals that are proportional to the flow.In addition, the transmitter is fitted with a flow indicator,two totalizers (main and daily count) for measuringquantities and two adjustable switching relays.A battery-driven unit can be used for the effectivedisplay of the totalizers and the flow.The convenient, multi-language operating menucontains special functions such as Teach-in for theK-factor correction, flow simulation for the “dry processtest” and so on.• Flow indication including 2 totalizers(flow rate and volume)• Automatic calibration: TEACH-IN• Simulation: all output signals provided withoutthe need for real flow.Technical dataMeasurement range from 0.2 m 3 /h up to 4500 m 3 /hFlow velocityAccuracy 1)Teach-In (via a remote transmitter)Standard K-factorRepeatabilityElectrical connection0.3 to 10 m/s (Hall version) - 0.5 to 10 m/s (Coil version -battery)≤ ±0.5% o.F.S.* (at 10 m/s)≤ ±(0.5% o.F.S.* + 2.5% o.R.*)≤ 0.4% o.R.*Cable plug acc. to DIN EN 175301-803, cable glandsM 20 x 1.5 or none (for battery version)Voltage 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 bearing / Seal300 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 consumptionOutputsCurrent signalPulseRelayBattery IndicatorOperating voltageOutputPLC* 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 relays≤ 20 mA without relay4-20 mA,max. load: 900 Ω at 30 V DC, 500 Ω at 24 V DC,100 Ω at 15 V DC, 800 Ω at 230 V ACTransistor open collector, NPN/PNP, 0... 30 V DC,100 mA, protected2 relays, 3A, 230 VAC, freely programmable2 x 9 V DC batteriesNone1) under reference conditions, i.e. fluid = water, temperatures = 20°C,up and downstream distances respected, adapted dimensions and pipesSubject to modifications
