A New FID System for VOC Analysis

The SmartFID, from ErsaTec GmbH (Germany) is a portable heated flame ionisation detector (FID) for measuring total carbon in VOCs e.g. MAC, process monitoring,

emission detection etc. SmartFID combines proven technology with new features such as automated

ignition, automated calibration,

integrated data logger with export function in different formats on USB and remote operation via Ethernet.

Automatic range switchover ensures that the measurements are always carried out in the correct range. The instrument is equipped with a 7” QVGA colour TFT touch screen allowing for user-friendly operation including a help-system. By using the free configurable feature calibration ratio, SmartFID analyses the output of measured value in mg C, mg compound, ppm or % LEL. The necessary air-conditioning is achieved by an integrated catalyser and all relevant interfaces and filters are easy accessible. During operation the device performs auto diagnosis and displays maintenance requirements. Additionally, the operator may use the tendency visualisation to watch the development of the measured value or to look for peaks in the elapsed time period.

In addition to the mobile version SmartFID is also available as a stationary 19” / 4 RU unit.

Flow Meter Measures Hydrogen Gas Accurately & Safely for Process Control

Instrument and plant engineers responsible for managing processes with a wide range of hydrogen gas applications will find the ST100 Series Thermal Flow Meter from US based Fluid Components International (FCI) (USA) provides precision mass flow measurement in a no-moving parts instrument featuring compliance with the necessary major safety approvals for the Americas and worldwide.

is used is in the manufacture of ammonia, which

also plays an important role in the production of methanol, which supports the manufacture of as a clean energy source for cars, trucks and buses.

The manufacture of hydrogen gas typically requires the refining of methane or other light hydrocarbons from natural gas or oil. Light hydrocarbon gas is mixed with steam and then the process continues with a complex series of steps that includes heating in a high temperature furnace to create a chemical reaction, which eventually results in hydrogen gas. Throughout this process, accurate flow measurement is essential with a rugged and reliable air/gas meter.

The ST100 Series Flow Meter is ideal for hydrogen gas production processes and supports other industrial applications of H2 . A sophisticated thermal dispersion

technology air/gas flow meter, the ST100 Flow Meter combines feature- and function-rich electronics with advanced flow sensors for advanced air/gas flow measurement. Offering direct gas flow measurement, no additional sensors or flow calculating devices are required for measurement. Its no moving parts design also virtually eliminates wear, breakage and maintenance.

The ST100 Flow Meter can be calibrated to measure H2 or 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. With the ST100 meter, H2

also can be measured safely at high flow rates from 0 to 6,600 lb/hr (0 to 3,000 kg/hr) at 29 to 87 psi.

When selecting the ST100 meter, users have multiple communication options. They can choose from: 4-20 mA analog, frequency/pulse, or certified digital bus communications such as HART, Foundation Fieldbus, Profibus PA or Modbus RS485.

Developed with a graphical, multivariable backlit LCD display, the ST100 meter brings new meaning to the term “process information”. Its sophisticated readout continuously displays all process measurements and alarm status for easy on-site viewing by technicians, and it has the ability to query for service diagnostics.

The ST100 meter’s electronics include a user selectable and programmable data logger. Readings are stored in a removable, internal micro-SD card. The micro-SD card has a 2 GB capacity capable of storing approximately 21 million readings. Recording time base is user selectable with a maximum rate of 1 reading per second. The logging feature is selectable via the front panel menu or via the serial port and configuration software tools.

The feature-rich ST100 meter utilizes constant power thermal mass flow sensing technology that measure flow with 100:1 turndown in ranges from 0.006 to 1850 SCFM [0.01 to 3140 NCMH]. The transmitter/ electronics can be integrally mounted with the flow body or may be remote mounted to 1000 feet [305m] away. The transmitter enclosure is NEMA4X/IP67 rated and available in painted aluminum or stainless steel.

ST100 meters are agency approved for hazardous environment installations. FCI products undergo rigorous agency testing and obtain their approvals on the entire instrument, not just the enclosure. Approvals available for the ST100 Flow Meter include: FM, FMc, ATEX, IECEx, EAC/TRCU, CPA, NEPSI, InMetro, and CE Approved.

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.

High Pressure Multiphase Mud Flow Solution Introduced

Bell Technologies (USA), LLC introduces the MULTIPHASE TORUSWEDGE (MPT) – a high-pressure flow meter for safely measuring multiphase volumetric flow rates for wellbore processes.

The meter is designed to provide high accuracy volumetric flow measurement on drilling rigs and can be used for multiple applications ranging from low to extremely high pressure. The MPT is particularly suited to mud flow where fluid is injected into the well through high-pressure high volume injection pumps. Mud is then returned to the surface through the bell nipple where it flows through the shaker for cleaning prior to being re-circulated back to the wellbore. The product handles demanding applications that require robust performance combined with low maintenance. The MPT will allow operators to confidently monitor mud flow both in and out of the well and ensure long term asset reliability as well as safe operation of the rig.

By monitoring the complete mud flow process, the rig operator will be able to safely control the drilling process and provide a more economically priced wellbore.

Reliable Sulphur Impurity Measurement at ppb Levels in Pure CO2
