1 / Flow / Variable Area SM-5 Plastic Flowmeters as per the Variable Area Principle Description: Features / For every industrial application / For fluid and gaseous media / Simple and robust design with high operational safety / PVC, PA, PSU and PVDF versions / Low pressure drop / Easy to assemble The SM-5 series of flowmeters operates according to the proven variable area principle. The float gets lifted by the flowing medium and indicates the flow with its upper edge on the scale attached to the device. If floats with integrated magnets are used, optionally, alarm contacts or a measuring transmitter can be attached to the device. All devices possess a male thread on the measuring tube and are additionally equipped with standard PVC adhesive sleeves. As an option, also female threaded fittings made of PVC, PP, brass or stainless steel can be supplied. Application: Due to a wide variety of materials and easily interchangeable measurement scales, the SM-5 series plastic flowmeters can be deployed for most of media including hostile media. The main areas of application are water treatment, effluent technology, chemical and food-processing industries and many others. / High resolution scale / Optional alarm contacts and analogue output address Twischlehe 5 D-7580 Bremerhaven Germany tel +49 (0) fax +49 (0) mail info@profimess.de web profimess.com rev. 07- / 475

The unit comprises a reed chain, the respective evaluation and implementation. Thanks to the -wire technology voltage supply and output signal do not run separated from each other. The exact magnet field sensors of the receiver capture the height of the magnetic float and covert its position continually into a ma output signal. This signal can be directly further processed.

3 / Flow / Variable Area Indicator Dimensions: Operating Ranges (Table ): For the media water (in l/h) and air (in Nm 3 /h) at relative operating pressures of 0,, and 3 bar, standard scales are available. For other media such as air at higher operating pressure, HCL (30%), NaOH (30%) and, for the units m³/h, l/sec., l/min, USGPM or IGPM, special type scales can be supplied on request. These supplementary special type scales can be attached later easily and reliably on the flowmeter. There is no need of any modifications to the measuring device. For other media and/or operational conditions, special type scale can be offered on request. For this, the following data is required: - Medium - Operating pressure - Operating temperature - Operating density - Operating viscosity Limit contacts (optional): Measuring tube Operating range Water (l/h) Air at +0 C (Nm³/h) not for PVC measuring tubes 0 bar rel. bar rel. bar rel. 3 bar rel Version / Contact function / bistable reed contacts.
