Analytical Sensors with Integrated Transmitter
Water Technologies Presented To Global Water Industry Leaders
Modern Water plc (UK), the owner of leading water technologies for the production of fresh water and monitoring of water quality, has recently presented at the 2013 Citi Water conference in London which was attended by many global water industry leaders.
The presentation on Water Scarcity Solutions: Desalination verses Water Reuse was given by Modern Water’s Executive Chairman, Neil McDougall and looked at how Modern Water’s innovative forward osmosis technology can help the world’s most water stressed countries.
The delegates heard how unlike traditional desalination, Modern Water’s forward osmosis process requires up to 40% less energy, produces a better quality of water with lower levels of contaminants, especially boron. Forward osmosis plants also have a far lower operational cost due to lower fouling of the membranes in the plant which therefore give the membranes a longer life as well as allowing the plant to continuously operate.
Modern Water’s Executive Chairman, Neil McDougall, commented: “We are delighted that forward osmosis has been recognised as one of the hottest topics in the water industry and that Modern Water has been given the opportunity to present at this prestigious event in the City of London.”
KROHNE, Inc. (USA) have announced the availability of SMARTSENS, the first family of 2-wire loop powered analytical sensors with integrated transmitter technology. SMARTSENS offers direct connection of sensors to process control systems and can be installed in explosive and hygienic areas. SMARTSENS is ideal for chemical, pharmaceutical, food and beverage applications, as well as power, water and wastewater. SMARTSENS can be configured and calibrated offline via PACTware.
SMARTSENS sensors significantly reduce the risk of failures along the chain from sensor to process control system. Offered for pH, oxidation- reduction potential (ORP) and conductivity, SMARTSENS sensors can be connected directly to the process control system, featuring direct communication via 4…20 mA/HART. This reduces common issues related to improper transmitter installation, cabling, or configuration. KROHNE is the first provider to offer a direct connection from sensor to the process control system via a standardised fieldbus.
All SMARTSENS sensors are digital and can be calibrated or recalibrated offline in a laboratory under controlled conditions. For offline calibration, the sensor can be connected directly to a PC running the same PACTware (FDT/DTM) as applied in the asset management system, using a USB interface cable for bi-directional HART 7 communication and power supply. This is a significant improvement over other analogue analytical sensors that have to be calibrated on site together with the transmitter, even if installed at remote or difficult-to-reach measuring points, which can also cause sensor calibration to trigger false values in the process control system.
Along with the sensor family, KROHNE has introduced a large portfolio of SMARTSENS accessories, including loop powered displays, USB interface cable and mounting assemblies.

25821pr@reply-direct.com New Digital Portable Photometer
Ponsel Mesure (France) innovates and presents a new digital portable photometer dedicated to the quality controls of water: Photopod.
Developed to answer all the constraints of measure on the ground and in laboratory, the set Odeon-Photopod is a unique offer stemming from an overall of a compact, strong and tight photometer and from a portable device physico-chemical multiparameter.
Odeon is a handheld multiparameter on which you can plug different types of numerical sensors that can measure pH, T°, ORP, conductivity, DO (optical sensor), turbidity, etc.
The Photopod is a device you can plug on the Odeon in order to do photometric analysis.
Thanks to 5 different wavelengths available, there are many parameters that Photopod can measure such as NH4+
, Cl2, Fe, COD. Methods of analysis are easy to realise and do not require a technical background in chemistry. With
PO43-
the "plug and play" technology of the digital sensors, the Odeon-Photopod is a concentration of intelligence and reliability allowing you to answer all your measurement requirements dedicated to the analysis of water: urban residual water and manufacturers, drinking water, boiler room, fish farming, natural waters.
Photopod is a unique innovation born from the meeting of Ponsel and Orchidis. Those companies are both owned by the Aqualabo Group. Ponsel is an expert in numerical technology, the multiparameter Odeon is already one of Ponsel’s best seller. Orchidis manufactures chemical reagents, and a photometer dedicated to water analysis was previously developed by the company. So the Photopod symbolises a real achievement for the two companies putting together their knowledge and experience in order to propose a new concept.
Photopod can be used with Odeon sold previously (under some conditions) so for those who already own an Odeon, it will be possible to have a multiparameter photometer for a very low price. Indeed, because it has no screen and no keyboard, Photopod can be offered at a very attractive price, that also makes it an eco-friendly device.

Water Level and Temperature Logger Simplifies Deployment and Data Collection
The Aquaread (UK) LeveLine is a self contained data-logging device that records water level and temperature continuously during its deployment. It features a highly accurate Piezoresistive, ceramic pressure sensor and a temperature thermistor, which are powered for up to 10 years by the internal 3.6V lithium battery.
Capture the water level data as quickly as 10 times per second and store up to 500,000 data records on the instrument’s built-in memory. All this technology is neatly sealed within a small, corrosion resistant, titanium housing (22mm x 186mm) that can be deployed to measure either absolute or gauge pressure.
Deployment simpler: The LeveLine is the only water level data logger that utilises the QuickDeploy key allowing you to initiate preprogrammed logging schemes as you deploy. The QuickDeploy key also zeroes the depth against the measured air pressure and checks the battery and memory levels giving simple LED indications. This simple sanity check could save you a costly mistake.
Data collection simpler: The GPS LeveLine meter is an accessory that can be used to define and initiate a logging scheme live in the field. When connecting the meter to the LeveLine logger at the time of deployment, the GPS location coordinates are embedded into the memory of the logger. This can make post-organisation of multiple units much easier as each unit has its precise deployment location embedded into it. No time-consuming serial number cross-referencing required here. Using the LeveLine PC application you can produce a Google Earth map of your deployment site with markers for each LeveLine, which will display key data when selected.
The advanced specifications of the LeveLine already make this instrument stand out from the crowd. By simplifying both deployment and data collection, using the novel quick deploy key and the unique GPS embedding features, the LeveLine should be your first choice for water level monitoring.
