WATER / WASTEWATER 21


Ultrasonic flowmeter ideal for ultra-pure water applications Designed primarily for ultra-pure water dispensing applications requiring a high degree of cleanliness, clean bore flow measurement devices such as


Titan Enterprises’ Metraflow® ultrasonic flowmeter, offer the ideal solution.


Ultra-pure water - water that has been purified to very strict specifications – is an important component for industries across specialist markets where impurities can cause product contamination or impact process efficiency.


Ultra-pure water (UPW) systems, typically used in production and cleaning processes within the pharmaceutical, medical, semiconductor and power industries, require a selection of technologies and equipment that preserve the purity of materials. It is crucial that any flow measurement device used in UPW systems can cope with low flow rates and are constructed from ultra-pure materials that cannot contaminate the liquids being measured. Maintaining hygienic, sterile and sanitary conditions within these processes is critical.


Semiconductor and microelectronic device manufacturers use UPW in the manufacture of circuit boards and as a cleaning/etching agent. It is imperative to preserve the purity of process fluids as contaminants or particles can lodge on circuits and cause microchip failures.


In the power industry, UPW is typically used as a source to make steam to drive turbine combustors and to steam boilers. The higher the boiler pressure, the higher the purity of water required.


Pharmaceutical and biotechnology facilities use UPW as a cleaning agent and a diluent for multiple-dose injections as well as an ingredient in products. Water free of endotoxins, microbes and viruses is essential in these applications and others such as inhalation therapy products, internal irrigation therapy products and bulk preparation of medicines.


Even in the food and beverage industries, water purity plays an important role in production, with some beverages, such as beer, requiring specific mineral compositions for the water used. The Metraflow®


performance Perfluoroalkoxy Alkane (PFA) polymer.


Neil Hannay, Senior R&D Engineer with Titan Enterprises, says: “Ultra-pure water can become easily contaminated by atmosphere passing through tiny leaks or diffusing through thin wall polymer tubing used for flow measurement. PFA polymer was chosen specifically as an advanced tubing option for the Metraflow®


as it offers excellent chemical inertness, is able to withstand damage by dangerous


contaminants, prevents accumulation of particles and has an ultra-high grade of purity.” Titan’s Metraflow®


Neil Hannay adds: “Whilst Metraflow®


is non-intrusive with no internal moving parts, designed to precisely monitor process flows at temperatures from 10ºC to 60ºC (140ºF) and pressures up to 27 bar. In addition, this non- invasive single tube ultrasonic flow meter gives a wide operating flow range with an accuracy of +/-0.5% FSD and repeatability across flow ranges from 20 to 5000 ml/min.


is the perfect pure water flow meter, the ultrasonic measuring device is also ideal for the flow measurement of challenging liquids and fluids, its wide flow range and


PFA (FDA approved) tubing making it highly suited to aggressive chemical flow measurement.” For More Info, email:

Cutting-edge electromagnetic portable flow meters spotlighted at WWEM Virtual Event


Aqua Data’s “Fluvia” and “FloStick” flowmeters offer several significant advantages over other flow and velocity measuring techniques.


Instruments which depend on momentum exchange with the water for example, such as impellers, Pelton wheels, screws, or turbines, are prone to clogging from impurities or debris in the water and are therefore unsuitable for wastewater or any ‘real world’ liquid. Devices relying on Doppler, ultrasound or laser effects usually need careful setting up, may be sensitive to temperature or orientation, and often require time consuming calibration for the situation in question.


“Fluvia” and “FloStick” electromagnetic devices can be used for virtually any liquid as long as it has at least some conductivity, and that is why suspended solids cause no significant errors at all; they


will induce an electromagnetic field at the electrodes just as moving water does. A ‘Faraday’ probe detects the bulk velocity over the entire area of the magnetic field, no matter what the moving material is. Dirty or ice-cold water will therefore not affect the accuracy of your readings.


Anyone who works on several tasks at the same time as a multitasker will love it. The new SD 335 Multi is available and can measure several parameters simultaneously. However, the multi-talent for electrochemical measurements can do even more in water analysis. It literally follows the user at every turn, even in demanding environments. Lovibond® has designed the instrument specifically for a wide range of requirements and applications.


The SD 335 Multi masters all the important parameters for wastewater treatment, pool water control, routine work in specialised laboratories, boiler and cooling water, the treatment of drinking water, the control of water pollution or for research applications. Two parameters and additionally the temperature can be measured simultaneously from a comprehensive range: pH, ORP, conductivity, TDS, salinity, dissolved oxygen (concentration and saturation).


The SD355 Multi features galvanically isolated measuring inputs, robust armouring including 2 electrode holders, a data logger with up to 8 GB data memory, easy data transfer via Micro-USB in CSV format, graphical, multi-parameter display and intuitive user interface in 7 languages and rechargeable NiMH-batteries. Operators can be walked through the simple, step-by-step calibration and there is even a convenient belt clip for mobile usage. The SD 335 Multi is offered in 3 different sets for the most diverse requirements.
