Promass

With its 14-inch diameter and accuracy up to 0.05%, the Promass 83X/84X four-tube Coriolis mass flowmeter is ideal for pipeline custody transfer and other high flow rate applications requiring reliability and low maintenance.

Endress+Hauser will be exhibiting the Promass 83X/84X at the Offshore Technology Conference in the Reliant Arena, Booth 7602, May 2-5, 2011, Houston, Texas.

Endress+Hauser announces the Proline Promass 83X/84X Coriolis flowmeter, the first large four-tube Coriolis flowmeter in the world. 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% flow accuracy, and optionally with a flow accuracy of 0.05%. The 84X is suitable for custody transfer applications, featuring MID (OIML R117) and PTB approvals.

For both models, accuracy of the density measurement is 0.01 g/cm3 (0.001 g/cm3 optional), while accuracy of the temperature measurement is 0.5 °C. Both models also have a balanced measuring system with high immunity to external pipe vibrations and process influences, and both work in applications with entrained air.

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, it accommodates most large pipelines worldwide. It replaces conventional flow measurement devices in pipelines with a flowmeter that's more stable and has a lower pressure drop. Like every other Endress+Hauser flowmeter, it has sophisticated and advanced diagnostics that help minimize maintenance costs.

Previously, companies had to use less-accurate conventional flowmeters on larger pipe sizes. Now that the Proline Promass 83X/84X is available in a 14-inch size, companies can use it for custody transfer, fiscal metering and other high required accuracy applications of gases and fluids. Typical applications include pipelines and transfers to and from tanker ships, trucks and railroad cars.

This 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 °F (-50 to 180 °C), and in process pressures up to 1,440 psi (100 bar). 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 v marks.

The Promass X will be available in Q3/2011.
