Ultrasonic Flow Meter for Ultra-Pure Water Applications
Ultrasonic Flow Meter 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.

For the needs of different industries

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.

High chemical inertness

The Metraflow® uses Titan’s patented ultrasonic time of flight technology to accurately measure liquid travelling through the clear, single, clean bore measurement flow tube constructed from high 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.”

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.
