Type S0 Type 869 Type 86 Type 8644 Type 2 (8692) Type 30 INSERTION fitting multicell transmitter/controller Universal process controller econtrol Valve islands control valve system On/Off diaphragm valve The Bürkert flowmeter Type is a compact device, specially designed for measuring the flow rate in solid-free liquids, in a variety of applications (water, waste water monitoring, chemical processing etc.). Type is available with: - 2 configurable outputs: one transistor output (NPN) and one 4... ma current output (2-wire) - 3 configurable outputs: two transistor outputs (NPN/PNP) and one 4... ma current output (2-wire) - 4 configurable outputs: two transistor outputs (NPN/PNP) and two 4... ma current outputs (3-wire). Type converts the measured signal, displays different values in different units (if display/configuration module mounted) and computes the output signals, which are provided via one or two M2 fixed connectors. Thanks to or 2 transistor outputs, the flowmeter can be used to switch a solenoid valve, activate an alarm and, thanks to or 2 current outputs, establish one or two control loops.

3 Design and operating principle The device is equipped with a sensor with a paddle wheel, available in long or short version (dependent on the size of the used fitting). This sensor holder is plugged-in and pinned to an enclosure with cover containing the electronic module. A removable display/configuration module completes this flowmeter. The flowmeter can operate without the display/configuration module, but it will be required for configuration of the device (i.e. set parameters, restore default parameters, configure information to be displayed, enter access codes, adjust 4... ma output(s)...) and also for visualizing continuously the measured and processed data. When liquid flows through the pipe, the paddle wheel with 4 inserted magnets is set in rotation, producing a measuring signal in the sensor (Hall sensor). The frequency modulated induced voltage is proportional to the flow velocity of the fluid. A conversion coefficient (K-factor, available in the instruction manual of the S0 fitting), specific to each pipe (size and material) enables the conversion of this frequency into flow rate. The electronic component converts the measured signal into several outputs (according to the flowmeter version) and displays the actual value. Totalizers are used to obtain the volume of fluid passed through the pipe. Installation The flowmeter can easily be installed into any Bürkert INSERTION fitting system (S0), 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. Fore 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.

The suitable pipe size is selected using the diagram Flow/Velocity/DN. The flowmeter is not designed for gas flow measurement. 3/8
