Yokogawa RAMC Rotameter RAMC Variable Area Flowmeter RAMC02-A1SS-63S2-E90424/SD/KS2

At first glance the instrument looks impressive with its all stainless steel design. A closer look reveals a unique patented "float blockage" detection system. Operational safety is of the utmost importance in any flowmeter, and the RAMC is no exception – wetted parts are available in a variety of materials, and intrinsically safe utputs are available as an option.

If you value flexibility in a flowmeter – from the measurement of air to highly aggressive liquids – in situ replacement of the indicator without loss of performance – and the interchangeability of floats – then the RAMC is the right choice for you.

The RAMC combines all the advantages of the variable area principle with robust design, reliable measurement, with or without power, HART® or Profibus PA, culminating in a truly universal flowmeter for gases, liquids and steam applications. 

Description of Yokogawa RAMC Rotameter RAMC Variable Area Flowmeter RAMC02-A1SS-63S2-E90424/SD/KS2

The short-tube Rotameter is used for measurement of flow rates of liquids and gases. Its special application is in troubled, opaque or aggressive mediums. The instrument is mounted in a vertical pipeline with flow direction upwards.

Inside the special shaped conicmetal tube, a float is guided concentrically. The position of this float is magnetically transmitted to the indicator. The indicators are exchangeable without influence on the accuracy.
