Thermal Mass Flow Meter Provides Precise Gas Measurement for Mud Logging Operations


Oil/gas engineers looking for a next-generation air/gas flow meter to support mud logging operations will find that the future-ready ST100 Series Thermal Mass Air/Gas Flow Meter from Fluid Components International (FCI, USA) offers the ability to measure flare gas flows under variable and low flow rate conditions.


Upstream oil/gas production companies around the globe depend on mud logging service companies to analyse mud samples that help them maintain the correct direction for their drilling field operations. In mud logging, samples of rock cuttings from bore holes are brought to the surface by recirculating drilling media (mud) for analysis by a mobile laboratory to determine the lithology and fluid content of the sample.


As the mud is returned to the surface from down the hole, it also contains natural gas that is vented to a flare stack and burned off at low flow rates typically from 15 to 20 fps. U.S. Environmental


Protection Agency (EPA) Directive 40 CFR Part 98 requires measurement and reporting of these flare gas emissions from mud logging operations. To provide the U.S. EPA required flare gas data, mud logging service companies need an accurate, reliable gas flow meter able to measure gas flow at relatively low flow rates. FCI’s ST100 Series Thermal Mass Gas Flow Meter provides excellent accuracy at low flow rates combined with a turndown far in excess of 100:1, with an insertion style probe offering low pressure drop.


The ST100 Series Flow Meter sets a new industry benchmark in process and plant air/gas flow measurement, offering the most feature- rich and function-rich electronics available. The ST100’s performance delivers unsurpassed adaptability and value to meet plant gas flow measurement applications for today and tomorrow.


Whether the need is for 4-20 mA analogue, frequency/pulse, alarm relays or digital bus communications such as HART, Fieldbus, Profibus or Modbus, the ST100 is the solution. Should a plant’s needs change over time or an upgrade be desirable, the ST100 Flow Meter adapts as necessary with a plug-in card replacement that can be changed out by plant technicians in the field.


The ST100 Flow Meter’s unique graphical, multivariable, backlit LCD display/readout brings new meaning to the term “process information”. It provides the industry’s most comprehensive information with continuous display of all process measurements and alarm status, and the ability to interrogate for service diagnostics.


The user-friendly ST100 stores up to five unique calibration groups to accommodate broad flow ranges, differing mixtures of the same gas and multiple gases, and obtains up to 1000:1 turndown. Also standard is an on-board data logger with an easily accessible, removable 2-GB micro-SD memory card capable of storing 21 million readings.


The versatile ST100 Series is comprised of two core model families: ST and STP. ST meters measure both mass flow and temperature, and the exclusive STP family adds a third parameter, pressure, making the ST100 the world’s first triple-variable thermal flow meter. Both families include single-point and dual-element models as configurations outfitted with FCI’s exclusive in-situ calibration option, VeriCal.


The ST100 can be calibrated to measure virtually any process gas, including wet gas, mixed gases and dirty gases. The basic insertion style air/gas meter features a thermal flow sensing element that measures flow from 0.25 to 1000 SFPS (0.07 NMPS to 305 NMPS) with accuracy of ±0.75 percent of reading, ±0.5 percent of full scale.


Designed for rugged industrial processes and plants, ST100 Flow Meters include service up to 850ºF (454ºC) and are available with both integral and remote (up to 1000 feet [300 meters]) electronics versions. The ST100 is agency approved for hazardous environments, including the entire instrument, the transmitter and the rugged, NEMA 4X/IP67 rated enclosure. Instrument approvals in addition to SIL- 1 include ATEX, IECEx, FM and FMc.


Fluid Components International is a global company committed to meeting the needs of its customers through innovative solutions for the most challenging requirements for sensing, and measuring flow, pressure and temperature of gases.

Drawing upon over 40 years expertise and experience, Titan Enterprises (UK) are able to work with customers to produce flow meters of the highest standard for a broad base of Original Equipment Manufacturer (OEM) applications.


For OEM collaborations, Titan look to produce an optimised flow meter to match your exact application requirements and not compromise achievable results with a less than ideal sensor. The resultant device will be unique to your application but will still benefit from Titan’s well tried and tested modern manufacturing methods to ensure a competitive, high quality OEM solution. From an initial concept Titan can offer a complete service from budget costing through prototypes to full production. Often the cost of origination and tooling can be amortised over the life of the product. It may be as simple as replacing an obsolete product right through to developed a fully bespoke product tailored to the customers precise requirements.


Titan has partnered with OEM customers to provide optimised flow metering solutions for a wide range of applications including disposable medical flowmeters, dirty water flowmeters for cooling of glass bottle shears, bespoke oval gears for marine fuel flow, corrosion resistant meters for sterilising equipment and high pressure intrinsically safe units for offshore oil drilling additive injection.


All OEM flow meters produced by Titan are designed and manufactured to ISO9001 and calibrated to an uncertainty of ±0.25%. The company produces chemically resistant, high accuracy digital flow meters that are not only competitively priced but are engineered to give long-term reliable performance.

Valve World Expo Expands its Capacity to Meet Growing Demand


For More Info, email: email:


As early as eighteen months before the start of the 3rd Düsseldorf Valve World Expo, held at the Düsseldorf Exhibition Centre from 2 to 4 December 2014, the Düsseldorf trade fair organisers had decided to open and occupy another hall for the duration of the exhibition. So in addition to exhibition Halls 3 and 4, now both Hall 5 and the adjacent North Entrance will also be opened.


For 2014, organisers expect another increase in exhibitors. Opening the second entrance will allow exhibitors and visitors to use both the South Entrance on the Rhine and the North Entrance with the underground station.


The End Users’ Pavilion will be located in Hall 5 for the first time.


This is a special show in which, initially some 20 end users, i.e. the exhibitors’ customers, will present their corporate portfolios. The aim is to promote matchmaking between exhibitors and end users.


After Valve World Expo 2012, companies from the oil, water and chemical industries had expressly voiced the request to be presented at the next trade fair in 2014 in this format as a contact point for exhibitors.


Also new will be the location of the accompanying conference. While it used to be held in the rooms of the adjacent Congress Center Düsseldorf (accessed via the South Entrance), a large proportion of Conference events are now to be held in Hall 4: more compact, transparent and right in the middle of the action. This move means conference content is to be embedded in the exhibition activities and conference delegates are to be brought closer to exhibitor ranges.


Since the conference organiser, KCI from Kleve, expects further growth, Hall 4 is ideal to also accommodate growing attendance figures in future.
