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, aim to offer the ideal solution.
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.
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, said: “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.”
The instrument is non-intrusive with no internal moving parts, is designed to precisely monitor process flows at temperatures from 10ºC to 60ºC (140ºF) and pressures up to 27 bar. It gives a wide operating flow range with an accuracy of +/-0.5% FSD and repeatability across flow ranges from 20 to 5000 ml/min.
Neil added: “Whilst Metraflow 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 make it highly suited to aggressive chemical flow measurement.”
