YOKOGAWA short-stroke variable area Rotameter RAMC measures high flow rates with a fairly short metering tube. The stainless steel construction is safe for use with gas, steam and liquid measurements. It is designed for use with hazardous and dangerous applications, high-temperature applications, aggressive fluids and high pressure rates.The flowmeter is mounted inside a vertical pipe with upward flow direction. The metal Rotameter has an electronic transmitter combined with Hart communication and patented float blockage detection to provide the highest degree of safety. When there is a fluid flow but no movement of the float, an alarm will be generated and an error message sent out. The RAMC meter with float blockage detection satisfies IEC 61508 2005 requirements for SIL 1.
