VEGA: takes the pressure out of pressure measurement Implementing process automation with precise and reliable pressure transmitters from VEGA can greatly assist personnel responsible for overseeing water and wastewater treatment systems.This article outlines some key VEGA instruments for these applications and the advantages of standardising on one sensor brand.

W ater treatment companies recognise the advantages of incorporating pressure sensors throughout their treatment facilities. In principle, these tools are expected to streamline their processes, allowing them more time to focus on critical tasks. However, not all in strumentation is of the same standard, and inaccurate readings can lead to significant challenges and delays, resulting in equip ment damage, severe process disruptions and significant water and financial losses. Utilising sensors from different manu facturers might seem feasible from a technical standpoint but, in reality, it of ten proves to be problematic. One of the primary challenges encountered is related to the end-user experience, as each device requires unique configuration and setup procedures. Furthermore, the knowledge acquired for operating and calibrating one sensor does not necessarily transfer to another operator. Obtaining support for multiple devices can also be a significant hurdle. In some in stances, water treatment facilities are left to navigate the configuration and trouble shooting processes independently. Clients of VEGA have found that standardising their pressure devices with a single manu facturer significantly simplifies the opera tion of water treatment plants. VEGA offers invaluable support to its clients, assessing facilities and finding custom solutions for their unique chal

lenges and needs. It is not just the time investment, VEGA sensors offer unparal leled ease of configuration, precision and reliability. VEGA has introduced sensors equipped with Bluetooth connectivity, which allow operators to wirelessly moni tor, set up and adjust them through the VEGA Tools App. This App is available for download in the Google Play store as well as the Apple App Store. Some VEGA pressure sensor options include: • VEGADIF 85 universal pressure transmitters can handle influent and effluent flow metering in loca tions throughout systems, enabling water treatment facilities to obtain high-precision measurement and value detection. The VEGADIF 85 is highly reliable through the integrated overload diaphragm, and functions as a multivariable sensor through integrated measurement of absolute pressure, delivering the data treat ment plants can rely on. VEGABAR 38 pressure sensors can be used to measure levels on tanks and chemical feed and fill systems, making it easier for system operators to view the pressure status – thanks to the sensors’ innovative, configu rable colour LED light ring – and to manage on-site operations via the VDMA menu structure. These sen sors also offer easy integration into control systems through IO-Link •

communication.

• VEGABAR 82 pressure transmitters measure at inlets and outlets on valves. These unique sensors offer an abrasion-resistant ceramic measur ing cell, ensuring reliable operation in the toughest process conditions. They provide reliable measurement down to the last drop through the smallest measuring ranges with high accuracy. This in turn can enable massive cost savings on maintenance costs. VEGAWELL 51 sensors are suitable for continuous level measurement in deep wells/reservoirs and rivers, with a maximum cable length of 1 000 m. Robust ceramic measuring cells offer maximum overload and vacuum resistance, making them a highly reliable addition to any water treatment and distribution facility’s process automation arsenal. VEGA offers true benefits of process automation to companies operating in the water and wastewater industries. VEGA’s proven mix of precise, reliable instruments and commitment to customer support means that plant operators are empowered by process automation instead of struggling with usability or maintenance, freeing them to focus on their other responsibilities. In so doing, VEGA takes the pressure out of pressure measurement for these industries. www.vega.com/en-za •
