The Burkert designed fitting system ensures simple installation of the sensors into all pipes from 1/ to 1. The sensor produces frequency signal (coil or Hall effect), proportional to the flow rate, which can easily be transmitted and processed by: a Burkert remote transmitter/indicator (Type 8025/8034/8032 remote versions) a transmitter module 8023 into a 4 20 m output signal a pulse divider module 8021 into adjustable frequency output signal a batch controller 8600 mounted on a valve General data Compatibility with all fittings S020 (see corresp. datasheet) Materials Sensor housing VF Housing E Union nut C Cable plug, brass electro silver plated Materials wetted parts addle wheel VF xis and bearing Ceramic Seal FKM/EM Electrical connections Cable plug EN Voltage supply cable Cross section Recommended length 1.5 mm² max. max. 33 ft, shielded (coil sensor) max. 165 ft, shielded (hall sensor) Electrical data ower supply Coil version Hall version Hall low power version Current consumption with sensor Hall version Hall low power version Output: Frequency Coil version Hall version Hall low power version Reversed polarity of C None VC VC (via Burkert transmitter) < 50 m < 0.8 m lternating 0 10V, frequency: Hz, Transistor NN/N, open collector, max. 100 m, frequency: Hz Transistor NN, open collector, Frequency: Hz rotected Complete device data (fitting + electronic module) ipe diameter 1/ to 1 (N 15 to 400) Measuring range Hall Coil Medium temperature max.

2 Installation The flow sensor consists of a transducer and an open cell inline rotor. When immersed in the flow, the rotating inline rotor produces a frequency modulated measuring signal proportional to the flow. In a 2- or 3-wire system, the signal can be displayed or processed directly. The output signal is provided via a 4-pole cable plug per IN In the versions with 4-20 m/adjustable frequency output, an additional NEM 4 (I65) housing is plugged on the sensor instead of the cable plug. The output signals are available on a terminal strip inside the enclosure via a G 9 cable gland. ll parts in contact with fluid are in VF or ceramic, enabling use in aggressive fluids. rinciple of Operation When liquid flows through the pipe, the inline rotor is set in rotation producing a measuring signal in the transducer (coil or Hall Sensor). The induced voltage is C. The frequency and amplitude are proportional to the flow. The version 8020 low power flow sensor can only be operated with a flow transmitter 8025 in panel or wall mount version. It can measure flow from 1.0 ft/s (0.3 m/s) flow velocity. The flow sensor 8020 with coil requires no external power supply and measures flow from 1.6 ft/s (0.5 m/s) flow velocity. This flow sensor can also be operated with a flow transmitter 8025 in panel or wall mount version. The flow sensor 8020 with Hall Sensor requires an external power supply of VC and measures flow from 1.0 ft/s (0.3 m/s) flow velocity. The flow transmitter 8020 with 4-20 m output requires an external power supply of VC and measures flow from 1.0 ft/s (0.3 m/s) flow velocity. The flow sensor 8020 with adjustable frequency output requires an external power supply of VC and measures flow from 1.0 ft/s (0.3 m/s) flow velocity. Installation The recommended In and Outflow straight pipe length should permit 10x in and 3x out. ccording to pipe s design, necessary distances can be larger or use a flow conditioner to obtain the best accuracy. For more information, please refer to EN ISO The flow sensor can be installed in either horizontal or vertical pipes. flow sensor plastic ring plastic union nut The suitable pipe size is selected using the diagram on the next page. ressure and temperature ratings must be followed according to the selected fitting material (see next page).
