The short-stroke Rotameter allows the measurement of high flow rates using a relative short metering tube.

1 General Specifications Model RAMC-Series Metal Short-stroke Rotameter Rotameters operate on the principle of generating a condition of dynamic balance within the flow meter in which a float is positioned in accordance with the flow through the flow meter. The position of the float is magnetically transmitted to the indicator. The short-stroke Rotameter allows the measurement of high flow rates using a relative short metering tube. It is a stainless steel armoured construction for the safe measurement of a variety of liquids, gas and steam. It s special application is for hazardous, dangerous or aggressive fluids, for high temperatures and high pressure rates. The instrument is mounted in a vertical pipeline with flow direction upwards. FEATURES Different process connections like flanges according to DIN and ASME All wetted parts in stainless steel Different linings for aggressive fluids Maximum flow m 3 /h water resp m 3 /h air (20 C, bar abs.) Accuracy class 1.6 resp. 2.5 with lining according to VDI/VDE 3513 Conically forged and linearized tube Optional floatdamping to avoid vibrations of compressions with gas applications Optional heating jacket for steam or liquid heat carrier Indicator housing in stainless steel, aluminium or plastic of protection class IP65 Local indication without additional power supply Microprocessor controlled transmitter with 24 V, 115 V or 230 V power supply Intrinsically safe version (Ex) possible Optional inductive alarms Electronic transmitter as standard with local-controlling display with the following features: Flow indication (totalizer, percent, actual) Indication of different volume and massflow units Second (manual) calibration storing Patented float blocking indication function Signal output damping Error message indication YOKOGAWA Rotameter is a trademark of Rota Yokogawa GmbH & Co. KG, a subsidiary of Yokogawa Electric Corporation, Japan. Except in the United Kingdom where Rotameter is a trademark of Roxboro Group PLC. 10th edition

The distance to other ferrictic materials should not be less than 60 mm. - The strength of external magnetic fields close by the Rotameter should be approximately 0mT.
