FLOWSIC600 DRU ULTRASONIC GAS FLOW METER FOR UPSTREAM APPLICATIONS

UPSTREAM MEETS ULTRASONIC – REACHING A NEW MILESTONE

IN RANGEABILITY & REDUCED MAINTENANCE COSTS

Ultrasonic meters provide several advantages over differential pressure meters such as improved rangeability, a higher turndown, no calibration and valuable diagnostics. The FLOWSIC600 DRU, an innovative dual-path ultrasonic meter is tailor-made for upstream and gathering applications. Specially adapted sensors and path layout combines the benefits of a FLOWSIC600 with an unmatched reliability and robustness for upstream conditions. The special 10D upstream piping allows for high measurement accuracy even without high-pressure calibration, resulting in faster ROI due to the lower operational costs of a virtually maintenance-free meter.

FLOWSIC600 DRU –

improved quality in upstream gas metering.

Advanced diagnostics give you an advantage

The FLOWSIC600 DRU introduces a new diagnostic feature for the detection of liquids in the gas stream. Indication is typically provided when the gas volume fraction falls below 99.5 %. This feature can provide valuable information about the measurement quality and the performance of upstream components such as liquid separators. Additional diagnostic information can be monitored, which gives the user information about how the meter and the meter run is performing.

The additional parameters for each path are: the speed of sound, turbulence, the automatic gain control value, the signal validity parameter and analysis of the actual raw signal wave forms.

• The FLOWSIC600 DRU provides real-time monitoring of all diagnostic parameters, informs about the measurement conditions and generates a warning when parameters change significantly.

• Special design features ensure the FLOWSIC600 DRU is rugged even in wet gas conditions.

• Due to the decreased necessity for on-site checks and cleanings, your operating expenses stay low.

ULTRASONIC GAS FLOW METER FOR UPSTREAM APPLICATIONS FLOWSIC600 DRU

Rangeability and turndown

With a turndown ratio of up to 150 : 1 1 it covers flow ranges that usually require several differential pressure meters in different sizes. Diagnostics monitor the meter and process conditions, so that even large variations in flow and gas quality will not affect the measurement availability, which gives you peace of mind for natural gas production and gathering environments. By verifiable savings in CapEx and OpEx and less effort for maintenance, FLOWSIC600 DRU is an ideal alternative to differential pressure meters.

1 Below 0.9 m/s increased uncertainty

Virtually maintenance-free with self diagnostics

Ultrasonic technology is free of moving parts and has no wear and tear.

Equipped with the MEPAFLOW CBM firmware and software, FLOWSIC600 DRU monitors itself and processes changes using “real-time” monitoring of all diagnostic meter parameters. The innovative liquid loading detection feature provides indication of liquids inside the gas stream and allows you to optimize the process and plan maintenance of the

FLOWSIC600 DRU and other devices accordingly.

High accuracy without highpressure calibration

The special 10D inlet, superior manufacturing precision, extremely tight tolerances for each meter during the manufacturing process, and high quality components all enable the SICK

FLOWSIC600 DRU to ensure a ±1 % uncertainty without calibration. By eliminating the need for calibration, this feature alone can save start-up time and cost.

Long term stability

The FLOWSIC600 DRU keeps your costs low with long maintenance-free operating periods and high availability even in wet gas conditions. A high turndown ratio ensures reliable readings even with large variations in flow. Finally, the direct path layout is insensitive against pipeline fouling and further reduces maintenance effort, which underlines the long-term economic advantages of FLOWSIC600 DRU.

Highly durable

The FLOWSIC600 DRU is designed for use in harsh upstream environments.

High durability is made possible by hermetically sealed transducers made of titanium with special wet gas encapsulation, and a meter body that ensures that liquids and contaminants will not affect the meter performance.

Also, the integral meter design with sealed transducer cover and internal cable routing prevent harsh ambient conditions from harming the device. This gives you the certainty of meter longevity even in challenging conditions.

Profit from technology leadership in ultrasonic gas metering

SICK is the technology leader in ultrasonic gas measurement. We have more than 30 years experience in ultrasonic measurement technology and more than 10 years of field experience with

FLOWSIC600 in various applications.

This knowledge has now been transferred into FLOWSIC600 DRU in order to provide a suitable solution even for upstream measurements. Our customers rely on us when it comes to challenging applications – with FLOWSIC600 DRU they can do that in upstream, potentially wet gas applications as well.

In combination with SICK‘s leading ultrasonic transducer technology, continuous manufacturing process improvements, and our certified in-house calibration lab SICK offers a high level of production quality unmatched by anyone. Because of this, our manufacturing process for the FLOWSIC600 DRU results in a ±1 % uncertainty out-of-the-box performance without the need for high-pressure calibration.

Low manufacturing tolerances using the example of path length scatter

It starts with the meter body. Superior manufacturing precision and narrow tolerance limits ensure the utmost accuracy of geometric parameters of the meter body and its special 10D inlet piping. Long-term collaborations with our regional suppliers allow a thorough quality assurance level for all the high-quality components of the

FLOWSIC600 DRU.

High quality ultrasonic transducers for wet gas applications

High-quality transducers are the heart of our intelligent measurement devices. All transducers are made of titanium, are hermetically sealed without a matching layer and wet gas protected. SICK transducers are subject to precise geometrical dimensional and impedance checks before they are matched pairwise to provide the utmost accuracy on each ultrasonic path for superior performance.

Example results for zero point testing with strict acceptance criteria

After assembly of the meter, a zero flow verification test is performed to verify proper transit-time measurement. Zero flow stability dominantly affects a meter‘s low-flow performance. The acceptance criteria for FLOWSIC600 zero flow verification exceeds the requirements from AGA9, and therefore ensures good low-flow performance.

Each FLOWSIC600 DRU is subject to a 7-point ambient air low pressure calibration. Calibration is done on SICK’s in-house test benches, which are certified and traceable by Germany‘s national metrology institute, PTB. Quality acceptance criteria for the resulting meter characteristics ultimately ensure proper meter performance. Based on the calibration result and thorough statistical methods, each meter is individually corrected by calibration factors (based on flow-weighted mean error calculation).

Extensive testing was conducted during the development process of FLOWSIC600 DRU in order to create a good and repeatable correlation between low-pressure and high-pressure meter performance. To ensure the proper performance of each FLOWSIC600 DRU under high-pressure conditions in series production, permanent quality assurance measures have been installed. Population samples are periodically sent to certified high-pressure calibration labs to verify statistical treatment is relevant to the population. This increases the population database and ultimately decreases measurement uncertainty.

Product description

The FLOWSIC600 DRU is an innovative ultrasonic dual-path gas meter for upstream applications based on the

FLOWSIC600. The meter includes a 10D inlet piping (integrated for 3" and 4", flanged for 6"). With a turndown ratio of up to 150 : 1 1 it covers common flow ranges that usually require several orifice plates. Due to its special design, the FLOWSIC600 DRU provides low measurement uncertainty without need for a high-pressure flow calibration.

High quality components with superior manufacturing precision and wet gas resistant transducers ensure longterm measurement reliability even in challenging conditions. Equipped with

MEPAFLOW600 CBM firmware and software, the FLOWSIC600 DRU provides advanced diagnostic capabilities for real-time monitoring of the meter and the process. The ultrasonic measurement principle with direct path layout makes FLOWSIC600 DRU virtually maintenance-free – even with high liquid loads.
