42 Flow Level Pressure Proline Promass Coriolis Flowmeter


Endress+Hauser (Switzerland) have announced the Proline Promass 83O/84O Coriolis flowmeter for use in corrosive, high pressure and high temperature environments in the oil and gas industry. All materials that can come in contact with gasses and fluids are manufactured from super duplex stainless steel with 25% Cr (25 Cr duplex), which offers high protection against saline seawater, hydrogen sulphide, chloride, carbon dioxide and other corrosive materials found in crude oil and natural gas. The T316L stainless steel external design also resists corrosion from salt and sea water exposure.


The 25 Cr duplex sensing tube fulfils all requirements in accordance with NORSOK M-630 and NACE MR175/MR103; as well as corresponding Pressure Equipment Directives like PED Cat. III, ASME, CRN and AD2000. This makes the 83O/84O suitable for use on offshore drilling platforms, floating production storage and offloading (FPSO) facilities, on-shore well fields, custody transfer systems and refineries.


The 83O and 84O were also designed to handle the increasing pressure and temperature requirements of today’s oil and gas exploration environments. As easily-accessible resources are depleted, drilling is moving into deeper and more unfavourable environments. Oil and gas from such holdings often contain poisonous and chemically corrosive substances under very high pressures.


The 83O and 84O handle pressures up to 3,742 psi (258 Bar) and process temperatures from -40 to 392F (-40 to 200C). Both are available in lines sizes of 3, 4 and 6 inch diameters.


Every flowmeter is subjected to rigorous testing on accredited (ISO/IEC 17025) and fully traceable calibration facilities to a maximum measured error of ±0.05%. The 83O is approved for United States custody transfer per API MPMS Chapter 5.6 and AGA 11; NTEP and Measurement Canada weights and measures approvals are pending.


Promass 83O output configuration options include digital communications, supporting Foundation Fieldbus, Profibus PA or DP, EtherNet/IP or Modbus RS485 installations. Promass 84O analog outputs for 0-10 kHz phase shifted pulse/frequency are also available when custody transfer proving requirements are mandated.


When using the 4-20mA output with HART, intrinsically safe applications for Class 1 Division 1 and other hazardous locations can be satisfied. Promass O has been submitted for a SIL-2 rating for critical applications and complies with NE43 (NAMUR) safety standards, including operating down to 3.6 mA in a fail-safe condition.


Both have built-in diagnostics, and display clear English text errors and root causes on local displays in case of a fault. The flowmeters can also be commissioned and diagnosed with Endress+Hauser’s FieldCare software. If servicing is needed, its DAT function automatic data backup ensures automatic reconfiguration of a repaired or new meter without the need for recalibration.


Promass 83O/84O simultaneously measure mass flow, fluid density and temperature, are highly immune to external disturbances such as pipeline vibration, and are stable under changing process conditions such as pressure, density, temperature or viscosity.

New Gas Flow Meter Introduced


KROHNE, Inc. (Germany), a global technology specialist in the development, manufacture and distribution of accurate, reliable and cost effective measurement instrumentation for the process industries, announces its ALTOSONIC V12 gas flow meter. With the new ALTOSONIC V12, KROHNE has launched their next generation of ultrasonic gas flow meters


for custody transfer applications.


The ALTOSONIC V12 has 12 measuring chords, two of which are solely dedicated to diagnostic functions. Once commissioned, it continuously checks the operating status. The positioning of the chords in five horizontal parallel planes compensates for swirl and thus, provides reliable measurements, even with highly distorted flow profiles. The diagnostics in the ALTOSONIC V12 can reliably assess deposits, contamination or changes in wall roughness, so that maintenance can be scheduled according to actual needs.


In the development of the ALTOSONIC V12, KROHNE focused on two significant problems that customers encounter and which cannot be satisfactorily addressed by existing ultrasonic flow meters:


The first challenge was how to transfer the calibration curve obtained under ideal conditions in the high-pressure test rig to the real-life measuring station with its headers, strainers, bent pipes, etc. In order to solve this, hundreds of flow profiles in all kinds of applications were analysed as part of the product development. The result is that the ALTOSONIC V12 is now the first ultrasonic flow meter capable of complying with the ISO17089 and AGA9 standards having 5D straight inlet requirements without using a flow straightener.


The second challenge concerned self-monitoring of the flow meter during operation: In other words, defining the accuracy of billing after a certain period of operation. Applying the proven reflecting technique, the meter is able to detect not only changes in the flow profile, but also the changes in the cross sectional area. Through this, the ALTOSONIC V12 is capable of assessing process changes that existing ultrasonic flow meters cannot even detect.


The ALTOSONIC V12 meter is available in sizes 4” – 24”, an installation length of 3D, and a maximum operating pressure of 2200 psi. It is compatible with commonly used protocols and can be seamlessly integrated into any existing infrastructure.

Flow Meter Is Now Available With CE Marking For All Service Categories Under European Pressure Equipment Directive


To support McCrometer’s (USA) European customers, the high-accuracy, virtually no-maintenance Wafer-Cone Flow Meter meets the requirements of the European Community’s Pressure Equipment Directive (PED) 97/23/EC and is eligible for use throughout the region.


The PED standard was adopted by the European Parliament and the European Council in 1997. It provides standards for the design, manufacture, testing and the uniform assessment of equipment and assemblies operating in pressurised environments across the European Community.


CE Marking for all service categories under the Pressure Equipment directive (PED) 97/23/EC means that McCrometer’s European customers have third party assurance that the Wafer-Cone Flow Meter is safe for use in the pressurised environments found in industrial processes and plants. The Wafer-Cone Flow Meter meets essential safety requirements covering design, manufacture and testing; satisfies appropriate conformity assessment procedures; and carries the CE marking and other information.


The Wafer-Cone Flow Meter is ideal for liquid, gas or steam service in line sizes from 1 to 6 inches. The meter’s flangeless design makes installation easy, while the interchangeable cone offers flexibility to accommodate changing flow conditions without recalibration. When flow conditions change over time, the cone can be removed and replaced with a cone at a different beta ratio eliminating the need to buy a new meter.


Space-saving and field-proven, the Wafer-Cone Flow Meter can be installed virtually anywhere in a piping system or be easily retrofit into an existing piping layout. No moving parts, virtually no maintenance and an economical cost make it ideal for applications


including: well heads, gas, CO2 and water injection, gas lift, compressor anti-surge, fuel gas, separator discharge, biogas reactors, cooling systems, plant HVAC, process gas lines and more.


The Wafer-Cone Flow Meter’s unique differential pressure sensing technology with built-in flow conditioning greatly reduces the required straight pipe run for installation as compared with technologies such as orifice plates and Venturi meters. The Wafer- Conemeter is highly accurate and requires of straight run of only 1-3 pipe diameters upstream and 0-1 pipe diameters downstream to ensure measurement reliability. Its ability to self-condition flow makes it a space-saver, allowing for a reduction of the instrument overall footprint and weight.


The Wafer Cone Flow Meter’s built in flow conditioning and resulting stable flow profile achieve an accuracy of +1.0 percent, with a repeatability of +0.1 percent, and operates over a flow range of 10:1. The Wafer Cone Flow Meter raises the bar for economy, ease of use and performance.


The Wafer-Cone‘s design features a centrally-located cone inside a tube, which interacts with the fluid flow and reshapes the velocity profile to create a lower pressure region immediately downstream. The pressure difference exhibited between the static line pressure and the low pressure created downstream of the cone can be measured via two pressure sensing taps. One tap is placed slightly upstream of the cone and the other is located downstream of the cone. The pressure difference can then be incorporated into a derivation of the Bernoulli equation to determine the fluid flow rate.


The Wafer-Cone’s direct mount configuration minimises installation labour while ensuring accuracy. Direct mounting the transmitter eliminates impulse lines, which lowers installation costs and reduces potential leak points by more than 50 percent. Simple plug-and- play mounting ensures the meter is installed correctly and eliminates a potential source of flow measurement errors.
