36 Water / Wastewater Raving Success at ACHEMA: New Photometer Series
WTW’s (Germany) new photoLab 7100 VIS have succesfully been shown for the first time at ACHEMA in Frankfurt, June 15th to 19th.
With the proven combination of routine analysis and spectral analysis capabilities, plus the new, pioneering Optical Reagent-Free measurement (OptRF) for effluent water in sewage plants, the new photometers are even more powerful and versatile instruments than their predecessor models.
To support the new photometers, we share our know-how with you: our photometry compendium shows a new ‘how-to’ video every month and offers many additional articles and materials on photometry basics and principles for reading and downloading.

Density Compensation Module Offered for Water Cut Monitor
AMETEK Drexelbrook (USA) now offers a Density Compensation Module (DCM) for its Universal IV In-Line Water Cut Monitor
(CM). The module automatically compensates
for density changes that may occur in the composition of products and reduces the calibration requirements due to those changes.
The Universal IV CM is designed for high-accuracy water in oil measurement. The DCM allows the Universal IV CM to maintain its stated accuracy with variations in density up to 10 API, ensuring measurement accuracy from load to load regardless of changes in product composition.
The Universal IV utilises an electrical measurement (capacitance) and correlates that to water cut (% of oil in water). Those measurements can be affected by changes in density. Density compensation is done to correct for changes in electrical properties that may impact output measurement and is particularly suitable for midstream refinery and oil pipeline operators.
Along with the optional Density Compensation Module, the Universal IV CM features an in-line probe design that allows it to analyse a large representative sample of flowing fluid in real time. Its sensing element extends into the main process line, taking an average of the capacitive property of the fluid over its entire length. That ensures a smoother and more accurate response, regardless of the mixture. The monitor’s onboard electronics then computes the relationship between capacitance change and water cut.
The Universal IV CM also offers the industry’s highest pressure and temperature capabilities (1500 PSI and temperatures up to 450oF) as well as field-proven Cote-Shield technology, which ignores coating buildup on the probe. In addition, a temperature-compensation (TC) version is available that measures product temperature internally and calculates a true water cut reading at any temperature as long as the water is in liquid state (eg. 32oF to 212oF at ambient pressure).
Applications for the Universal IV CM include automatic well testing (AWT), lease automatic custody transfer (LACT), basic sediment and water (BS&W), separation vessels, pipeline slug detection, truck unloading, pipe protection, dielectric analysis and machinery lube oil monitoring.
AMETEK Drexelbrook is an acknowledged leader in level measurement with more than 50 years of industry experience. It offers a full range of process level measurement solutions, including RF Admittance/Capacitance, TDR/GWR, Radar, Ultrasonic, Magnetostrictive, Hydrostatic, Vibration, Conductive and Float devices.

Determining Water Quality in the Smallest of Spaces
For More Info, email: email:
To determine the quantity of dissolved organic compounds in a water sample, the spectral absorption coefficient (SAC) is measured at 254 nm. In order to integrate this important parameter of water in analysis in its online analysis system, OALab, Bürkert (Germany) has miniaturised the measuring principle and integrated it in a sensor cube for OALab.
For More Info, email: email:
The SAC sensor cube measures a mere 44 mm x 100 mm x 158 mm and can be used with a handle while the Bürkert OALab is running. It automatically conducts an optofluidic measurement of the water sample, including all calculations, averaging and corrections and transmits the result - the SAC value of the water - to the EDIP (efficient device integration platform), which enables intelligent networking of all electronic Bürkert devices.
The sensor consists of a lamp module with a Xenon flash lamp, a spectroscope and the electronics with integrated software. The software independently induces measuring cycles once the sensor is connected. During the measurement, the light pulse of the lamp passes through an opening at a 90° angle to a cuvette consisting of two sapphire windows. Sample water continuously flows through the cuvette. The light passes through a lens, an aperture, optical grid and a focussing lens to the 1.5 mm detector array. A complete, fully automatic microspectrometer for water samples the size of an OALab sensor cube is a pioneering innovation and underscores the microfluidic and system solution expertise of Bürkert Fluid Control

A Unique Solution for Accoustic Water Leak Detection
For More Info, email: email:
Aqua M300D is a portable, accoutic water leak detection instrument, from FAST GmbH (Germany). The Aque M300 D includes a clear and concise display panel to view the leak status effectively. 256 free and automatic adjustable filter settings achieve effective reduction of noise interference and therefore offer unsurpassed results. The instrument’s automatic adjustment and filtration of amplification ensures that even the smallest leak is located. Even the most advanced filter cannot suppress all interference noise, because of this some leaks are only partially audible. In these cases, the Aqua M-300D is fitted with the ultimate Tracer Gas Technology to locate the leak. This decades-proven, safe and accepted method by the international Water Wise Associations (DVGW, IWA, AWWA etc...) is now available for the first time in this smart combination.
The localisation of plastic pipes is still a major challenge. The Aqua M-300D, in combination with the PWG, offers an excellent complement to conventional systems, like ground radar and fiberglass detection probes. Aqua M300 D features a ‘pyramid mode’ which works by means of intelligent algorithms in the background to automatically optimise the leak information and thereby enable an unmatched precision in determining the location of the leak. By using these innovative and unique methods of measurement with a ultimate Chebyshev analogue with a filter width of 48 dB/octave slope, noise pollution effectively is eliminated. The integrated data logger function provides a highly detailed and accurate profile of the leak. This is particularly useful in situations with high levels of ambient noise. By recording the sound for a maximum of one hour and closing the pipeline to check, the leak noise can be safely distinguished from pollution noises.
