INSERTION paddle wheel flowmeter for continuous flow measurement Economic integration in pipe systems without any additional piping 3-wire frequency pulse version to directly interface with PLC s (both PNP and NPN) Connection to Bürkert devices in remote versions Type 800 can be combined with... Type 80 Flow transmitter Type 86 Universal Controller econtrol Type 880-GD TopControl system PLC The paddle wheel flowmeter for continuous flow measurement is especially designed for use in neutral, slightly aggressive, solid free liquids. The Bürkert designed fitting system ensures simple installation of the devices into all pipes from DN0 to DN400. The flowmeter produces a frequency pulse signal, proportional to the flow rate, which can easily be transmitted and processed by a Bürkert transmitter/controller.

Design and principle of operation The flowmeter 800 consists of a transducer and a paddle-wheel with ceramic bearings. The ceramic rotating axis is set on the end of a PVDF INSERTION sensor armature. The transducer is mounted inside the armature. In a 3-wire system, the signal can be displayed or processed directly. The output signal is provided via cable plug according to EN 730-803. When liquid flows through the pipe, the paddle-wheel is set in rotation. The non-wetted permanent magnets inserted in the paddle wheel generate a measuring signal which frequency is proportional to the flow velocity. A conversion coefficient (K-factor, available in the instruction manual of the fitting), specific to each pipe (size and material) enables the conversion of this frequency into flow rate. Two electronic module versions with frequency output are available: - with one pulse output (either NPN or PNP transistor output depending on wiring). An external power supply of - 36 V DC is required. It is designed for connection to any system with open collector NPN or PNP frequency input. - with one pulse Low Power output (NPN transistor output). An external power supply of - 36 V DC is required. Can only be connected to separate versions of flow transmitters Type 80/803. Installation The 800 flowmeter can easily be installed into any Bürkert INSERTION fitting system Type S00, by just fixing the main nut. Minimum straight upstream and downstream distances must be observed. According to the pipe s design, necessary distances can be bigger or use a flow conditioner to obtain the best accuracy. For more information, please refer to EN ISO 67-. EN ISO 67- prescribes the straight inlet and outlet distances that must be complied with when installing fittings in pipe lines in order to achieve calm flow conditions. The most important layouts that could lead to turbulence in the flow are shown below, together with the associated prescribed minimum inlet and outlet distances. These ensure calm, problem-free measurement conditions at the measurement point. Control valve DN = pipe diameter Flow direction --> x 90 elbow joint expansion x 90 elbow joint 3 dimensional 90 elbow joint or T-piece reduction The device can be installed into either horizontal or vertical pipes. Pressure and temperature ratings must be respected according to the selected fitting material. The suitable pipe size is selected using the diagram Flow/ Velocity/DN. The measuring device is not designed for gas flow measurement.
