Model RAMC Metal Short-stroke ROTAMETER General Specifications GS 01R01B02-00E-E The short-tube Rotameter is used for measurement of flow rates of liquids and gases. Its special application is in turbulent, opaque or aggressive fluids. The instrument is mounted in a vertical pipeline with flow direction upwards. Inside the special shaped conical metal tube, a float is guided concentrically. The position of this float is magnetically transmitted to the indicator. The indicators are exchangeable without influencing the accuracy. FEATURES • Different process connections like flanges according to EN and ASME • All wetted parts in stainless steel or PTFE • Flow range water: 0.0025 to 130 m3/h • Flow range air: 0.075 to 1400 m3/h (+20 °C, 1.013 bar abs) • Measuring accuracy acc. standard VDI/VDE 3513 sheet 2 (qG = 50 %) at calibration conditions • Float damping to avoid float bouncing with gas applications • Optional heat tracing (with steam or fluid heat carrier) • Indicator in steel or aluminum, protection class IP66/67 • Mechanical indicator without additional power supply • Microprocessor controlled transmitter with 24 V, 115 V or 230 V power supply • Intrinsically safe version (Ex i): ATEX, lECEx, FM (C/US), NEPSI, PESO, EAC • Flame proof version (Ex d): ATEX, IECEx, NEPSI, PESO, KOSHA, EAC, TS • Dust explosion proof: ATEX, IECEx, NEPSI, TS • Ex for non-electrical RAMC: ATEX, EAC • FMEDA report available for SIL application • Limit switches, also available as “fail-safe” version • Electronic transmitter as standard with digital display with the following features: ♦ Flow indication (totalizer, actual, percent) ♦ Indication of different volume- and mass flow units ♦ Possibility of user calibration in the field ♦ Float blocking indication function ♦ Adjustable signal output damping ♦ Error message indication ♦ Temperature measurement in the electronic transmitter ♦ HART® 5/7-Communication Rota Yokogawa GmbH & Co.
