MEASUREMENT & TESTING
Two standard fl ow sensing element confi gurations are available to meet the most demanding oil/gas industry application requirements. The FLT93S Switch is designed for use in standard heavy industrial applications and in applications with high velocity liquid setpoint requirements such as the fi re sprinkler system. The FLT9F confi guration is designed for fast response in air and gas applications and is commonly used in variety of other fl ow sensing applications on offshore platforms.
The precision FLT93S Switch is accurate in liquids to ± 0.5% reading or ± 0.012 mps (± 0.04 fps). This application also was well within the rugged FLT93S’s pressure operating limit of up to 240 bar[g] (3500 psig). An optional FLT93L in-line fl ow switch, for small line sizes, is capable of operating pressure of 690 bar (g) (10,000 psig)
The chosen fl ow switch features fi eld confi gurable dual SPDT or single DPDT relays rated to 6 amps at 115 Vac, 240 Vac or 24 Vdc. For this marine environment, the FLT93 was supplied with its optional, corrosion resistant 316L stainless steel enclosure. The sensor element itself is also all-welded, 316L stainless steel.
The sensor can be supplied optionally in other materials of construction such as Hastelloy C, Titanium or Monel. The highly

reliable FLT93S Switch has a 180-year mean time between failure (MBTF) rating. The FLT93 Series is rated as a SIL-2 device for safety instrumented systems (SIS). The instrument has been independently evaluated by industry expert exida for compliance. FCI is committed to safety in the hazardous industries and complying with IEC 61508 and 61511.
The FLT93’s hazardous area approval ratings on the full instrument also helped the manufacturer save on wire and installation costs. With its robust no-moving parts fl ow circuit design and the ultra- rugged enclosure, the switch offers long, worry-free service. Its no-moving parts design also eliminates the expense of routine maintenance checks.
Conclusions
After fi nal engineering fi rm design approval and installation of the fi rst units on offshore platforms, the FLT93S Switches have been in operation for over ten years and there have been no problems reported. The engineering design fi rm continues to use this switch in its fi re sprinkler systems and in other applications aboard offshore platforms.

Fast boiling point process analyser
Bartec Benke’s rapiDist-4 offers rapid, reliable and accurate boiling point measurements to allow for fast process control of atmospheric measurements, distillation columns and blending processes for all types of middle distillates and feedstock for petrochemical processing (naphtha), jet fuels, fuel oils, diesel fuels and similar petroleum products and liquid hydrocarbons.
The rapiDist-4 is capable of taking measurements from IBP to FBP. Programming the analyser is relatively simple and the results will correlate with ASTM D86. rapiDist-4 offers an optional ASTM D86 conform validation. The cycle time is only 10 to 15 minutes (10 minutes for diesel).
The RapiDist-4 will be exhibited by Bartek Benke’s Russian distributor, Scotrade, at the upcoming Neftegaz Exhibition taking place in Moscow between 26th to 29th November For More Info, email:

Generate VOC calibration gas standards from a liquid
Available from Alytech, France the LiqMix Cascade is an accurate, automated, cost effective way for on-site generation of gas standards for chemicals that are not commercially available in cylinders, such as unstable, reactive compounds in complex multicomponent mixtures. Calibration gas such as BTEX in air, other hydrocarbons, acetone, siloxanes, ethanol and phenol, humidity standards can be produced in your lab tailored to your needs.
This innovative multi-stage cascade dilution system can generate a standard gas from pure liquids or liquid mixtures in wide concentration range from % down to ppb with good accuracy, high repeatability, and full traceability. This makes the LiqMix Cascade a simple and reliable metrology tool to perform multi-point calibrations, linearity, and hysteresis checks, LOQ / LOD validation of gas sensors, GC or GC/MS systems and many other purposes. Liquid micro fl ow is delivered into a vaporizer precisely measured by Coriolis massfl ow controller where it injected into a fl ow of a carrier gas (air, N2
, H2 , He, … ). The Coriolis technology is virtually independent of liquid properties (temperature, density, conductivity, and viscosity) and can handle any liquid or liquid mixture without a need for a specifi c calibration very accurately.
To achieve very low concentrations a portion of homogenous gas/vapour mixture is delivered to the second dilution stage, so-called Cascade, where it is further diluted to desired ppb concentration. All interconnections and outlet line of LiqMix are heated in order to maintain the vapours in gas phase and thus avoiding re-condensation up to the delivery point.
Easy to handle, dedicated AlyTech GasMix software controls the operation, manages mass fl ow controllers, its calibration tables, performs automatic calculation of liquid and gas fl ows, to achieve desired concentration of analytes even for very complex multicomponent mixtures. Following highest metrology requirements the instrument not only accurately prepares the gas mixtures, but it also automatically calculates and reports maximum relative uncertainty for every delivered concentration.
Enhanced communication features of the software and automated programmed sequences enable full automation by synchronising the calibrator with a gas chromatograph, pre-concentrator, spectrometer, gas analyser or other system dramatically reducing labour time of analytical chemists.
The LiqMix Cascade saves a considerable amount of money and time by producing on-site calibration gas or customized gas mixtures for your specifi c needs.
