The Proline Promass 83X/84X Coriolis flowmeter, the first large four-tube Coriolis flowmeter in the world, according to the manufacturer. The 14-inch diameter flowmeter is ideal for measuring the mass flow, density and temperature of oil, gas and other fluids in large pipes at rates up to 4,100 tons/hr with extreme accuracy and precision. The 83X model comes standard with fully traceable 0.1 percent flow accuracy, and optionally with a flow accuracy of 0.05 percent. The 84X is suitable for custody transfer applications, featuring MID (OIML R117) and PTB approvals. The Promass X is the first commercially available four-tube Coriolis mass flowmeter. Its all 316L stainless steel construction makes it ideal for on- or offshore applications. Available with 12, 14 and 16-in. flanges.The four-tube flowmeter is made of 316L stainless steel with secondary containment for increased process safety, making it ideal for applications involving toxic or hazardous liquids or gases. The flowmeter has no moving parts, so maintenance is minimized. It operates in process temperatures of -58 to 356 degrees F, and in process pressures up to 1,440 psi. Communication options include 4-20mA, HART, Profibus DP/PA, FOUNDATION Fieldbus or Modbus. The flowmeters have a NEMA 4X/IP 67 rating and ATEX, FM, CSA and IECEx approvals. The Promass 83X/84X fulfills EMC requirements according to IEC/EN 61326 and NAMUR NE21. It also conforms to the requirements of the EU and ACMA directives and thus carries the CE and √ marks.
