FLUID HANDLING CLEAN WATER QUALITY BURKERT SMART CUBES FOR SMARTER WATER NETWORKS Maintaining clean water quality is extremely important for both consumers collecting it from the tap and for manufacturers that rely on it as a key constituent part of a process. Efficient measuring and monitoring of parameters such as pH, iron content and turbidity, is a constant challenge for many water utilities and food & beverage producers. Now there is a flexible, modular system that uses smart cube technology to save space, time and money. Traditionally, clean water analysis equipment has been bulky and time-consuming to install, not to mention the resource required to monitor and calibrate it regularly. Due to the importance of quality standards and compliance with statutory regulations that are applied for the safety of the general public, these short­comings have been unavoidable -until now. Experts in flow control technology at Bürkert have been applying some innovation in this field and as a result the company’s Type 8905 Online Analysis System is setting new standards in terms of flexibility, ease of use, installation time and reduced operating costs. As a compact, modular system it is far easier to integrate into an existing control infrastructure than typically in-line alternatives and can be adapted almost instantly for individual applications. SMART CUBES The secret to its success is plug-and-play sensor cubes that are capable of measuring pH, reduction potential (ORP), conductivity, free chlorine, chlorine dioxide, iron, and turbidity. Each cube, irrespective of its capabilities, has the same dimensions and connections and can be plugged in, or removed, from the unit while it is operational, thus providing a ‘hot swap’ facility. Each cube holds all the calibration data and mapping data that is required for it to operate without additional input from the operator. This onboard ‘intelligence’ means that any cube can be installed in a base unit and it will automatically configure itself and make its presence known to the rest of the system. This benefit is enhanced when it comes to ongoing calibration because now a process that was rather drawn out and time- consuming, can be completed in a matter of seconds. 82 PECM Issue 39 All cubes can be calibrated in a cleaner environment using a laptop and the associated calibration equipment. The ‘hot-swap’ function of the cubes means that an operational cube can be replaced with a recently calibrated cube from another sampling station. This allows a spare cube to be rotated across any number of sampling stations, all the time carrying its calibration with it. Looking at the individual sensor cubes and their calibration processes in detail it is possible to gain a better understanding of the advantages they have over more traditional monitoring systems.
