Measurement and Testing Conclusion
As change is the harbinger of opportunity, investing in state-of-the-art on-line process sulphur gauge technology - to gain commercial advantage by ensuring the flexible delivery of high quality and, certified products – is becoming an imperative for companies whose strategy is to become or remain a dominant player in the petroleum market.
While in-line blending has been around for years, older technologies are often not suitable to deliver performance to keep pace with modern needs in the petroleum industry or deliver precise enough blends to optimise profits in today’s economic environment. For the reliable on-line determination of sulphur, the new Rigaku NEX XT resolves those past issues and is thus an excellent tool for sulphur measurement in the optimum blending of crude oil, bunker fuels and other heavy hydrocarbon oils.

New Enhancement for Versatile Range of Field-proven Online Viscometers Hydramotion Ltd (USA) is pleased to announce a new enhancement for its versatile XL7 range of field-proven online process viscometers.
Ideal for petroleum products and lubricants, the XL7 offers continuous viscosity measurement with high resolution, excellent repeatability and virtually minimal maintenance. New to the range is the option of an integral temperature sensor, enabling the simultaneous monitoring of fluid temperature and calculation of temperature-corrected viscosity without the need for a separate thermowell.
With viscosity so dependent on temperature, the facility for measuring both at the same point offers a significant accuracy advantage, especially where measurement conditions may be changing unpredictably from minute to minute. The XL7 always operates at process temperature, which eliminates the chance of potential errors arising from localised cooling of the fluid. The high-temperature HT2 model can be used at up to 450o
C (842o F) without special cooling.
Unaffected by flow rate or bubbles of air or gas, and with no moving parts to wear out or fail in service, the XL7 is a “bolt-on-and-go” device requiring no spares and no accessories. It is factory-calibrated to certified viscosity standards traceable to NIST, so requires no on-site calibration. Measurements are unaffected by variations in flow rate or by the presence of suspended solids or gases. The instrument naturally rejects typical plant vibration frequencies, which gives a very high output stability even in extremely noisy wellhead or refinery environments.
The sensor is an all-welded construction which can be mounted on tanks or pipes at any location and in any orientation using any process fitting, with no need for any ancillary pipework. Calibration is unaffected by installation or environment. All instrument-specific data is stored on the transducer, giving complete flexibility of installation. Any XL7 model can be supplied in an intrinsically safe version certified to IEC Ex ia IIC, suitable for installation in all Hazardous Areas up to and including Zone 0 (explosive atmosphere continuously present), equivalent to Class 1 Division 1 Group A.
While traditional methods of measuring viscosity cannot be used at the high pressures sometimes encountered in oil industry applications, the unique technology of the XL7 imposes no theoretical limit on operating pressure. Hydramotion has recently supplied XL7s rated at 20,000 psi (1380 bar), and instruments with higher ratings are available.
The accompanying VP550 readout unit has a clear, easy-to-read display showing dynamic or kinematic viscosity, both “live” and corrected to a user-defined reference temperature. The user can select from a range of standard viscosity units including centipoise (cP), pascal-seconds (Pa·s) or centistokes (cSt) as desired. Conversion to other units is also possible. User-friendly intuitive software offers rapid access to any function or parameter for configuring or updating the system. Menu navigation is quick and easy using the simple-to-operate keypad. No programming is required.
There are three user-selectable 4-20mA analogue outputs, all fully configurable, as well as an RS485 serial data link for remote viscosity monitoring and control. The optional USB output facilitates direct connection to a PC or laptop.
Simple to hook up and use, the combination of XL7 transducer and VP550 readout unit gives a reliable, easy-to-use and durable viscosity measurement system with an unbeatably low cost of ownership. Ready for use straight out of the box, the high-performance XL7 is the viscometer of choice for oilfield or other aggressive environments where removal or replacement would be costly, inconvenient or impractical.
Reader Reply Card No High-resolution Infrared Camera for R&D Applications
FLIR Advanced Thermal Solutions (ATS) Group (France) has announced the release of its new FLIR SC655, a high-resolution uncooled infrared camera designed specifically for scientific and research and development applications.
Affordable, compact, and powerful, the FLIR SC655 provides provides both high frame rates and full 640 × 480 imagery enabling capture of over 300,000 pixels of accurate temperature measurement
data in a single image.
The FLIR SC655 is the world’s first high-resolution uncooled infrared camera to provide high-speed windowing modes, digital control of image flow and recording and to be fully compliant with both GenICam and GigE Vision protocols, making it ready to integrate with a variety of third-party analysis software packages.
This combination makes the FLIR SC655 the most effective tool available for infrared research, product development and non-destructive testing applications. The FLIR SC655 is the perfect tool to enable you to capture and record thermal distribution and variations in real time, so you can see and accurately quantify heat patterns, dissipation, leakage, and other heat-related factors in equipment, products and processes.
FLIR’s infrared science cameras give you the latest imaging and communication features you need to gather important data quickly and accurately. For intelligent, flexible cameras designed to meet the most demanding requirements, choose FLIR’s SC-Series infrared cameras.
