Ceramic lined flowmeter for concrete piling
A Yokogawa flowmeter is playing a key role in a novel application for one of the world's leading ground engineering contractors, inserting concrete into drilled piling holes
Applications range from refinery gasoline blending to non-contact identification of raw materials in the pharmaceutical industry.
FT-NIR technology, based on interferometry principles, can be used to measure virtually any property in a liquid stream that correlates to an infrared absorption band.
The instrument automatically applies absorption measurements to calibration curves prepared in advance, allowing concentration and properties to be evaluated using multivariable analysis software.

Online FT-NIR process analyser runs without a PC
Yokogawa UK has introduced a new multi-channel FT-NIR (Fourier transform near-infrared) online process analyser, offering high resolution, an excellent signal/noise ratio and high reliability
Compared with traditional laboratory analysis techniques which can take days, and are expensive in terms of chemicals and other consumables, FT-NIR measurement can be carried online in real time, making it ideally suited for plant monitoring and optimisation in a wide variety of process industries.
In addition to the benefits of high throughput and quick response time, the InfraSpec NR800 offers the additional advantages of exceptional stability, vibration resistance and durability resulting from its use of a purpose-designed Michelson interferometer with a vibration-resistant mechanism.
The instrument carries out measurements on up to four channels over a wavelength range from 0.9 to 2.5 microns, which includes the combination tone region (2.0-2.5 micron) required for OH-value measurement.
Resolution is down to 4 cm-1, and signal/noise ratio is 2250:1 (RMS at 4 cm-1).
Wavelength reproducibility is 0.007 cm-1 and wavelength accuracy is 0.04 cm-1.
Unlike many FT-NIR systems, the InfraSpec NR800 runs without a PC as a completely stand-alone system for online measurement, although external interfaces are provided for downloading measurement data and carrying out remote maintenance.
Software available for the instrument includes Spectland II for online monitoring and Unscrambler for chemometrics calibration and analysis.
Outlier detection and self-diagnosis functions are supplied as standard features.
For process applications, the InfraSpec NR800 can be supplied in both general-purpose and explosion-proof versions.
A desktop laboratory model is also available.
A wide range of flow cells, probes and other sample-handling accessories complete the analysis package.
