TAKING THE PRESSURE OUT OF WATER PRESSURE MANAGEMENT

Water treatment systems in metropolitan areas demand careful monitoring and management processes across sprawling networks. Process automation through the use of pressure transmitters can be a major aid to the personnel in charge of ensuring the operation of the many moving parts that make up a water treatment system.

In theory, these instruments allow water treatment companies to easily automate their processes so that they would have more time to work on more pressing matters. Not all instrumentation is created equal, and by receiving inaccurate readings, companies face major difficulties and delays, costing thousands of rands worth of equipment damage.

Using sensors from various manufacturers can be challenging. One of the biggest issues faced is the end-user experience, as the different devices each have a unique way of configuration and setup and the knowledge gained on learning to operate and calibrate a single sensor is not transferrable transferable to using another sensor.

Another hurdle could be obtaining support for each of these devices. In some cases, water treatment facilities are left to their own devices when configuring and troubleshooting are to be done. VEGA clients found that standardising their pressure devices to a single manufacturer simplifies the operation of the water treatment plants significantly.

• Using the VEGADIF 85 universal pressure transmitters to handle influent and effluent flow metering in locations throughout systems, water treatment facilities can obtain high-precision measurement value detection. The VEGADIF 85 is highly reliable through the integrated overload diaphragm, and functions as a multivariable sensor through integrated measurement of absolute reliable pressure. By using the VEGADIF 85, facilities obtain data that they can rely on.

• VEGABAR 38 pressure sensors can be utilised 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 sensor’s configurable colour LED light ring and on-site operation with its VDMA menu structure. This sensor offers easy integration into control systems through IO-Link communication.

• The VEGABAR 82 pressure transmitters measure at the inlets and outlets on vaults. This unique sensor offers an abrasion-resistant ceramic measuring cell, ensuring reliable operation in the toughest process conditions. It provides 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 is suitable for continuous level measurement in deep wells or reservoirs and rivers, with a maximum cable length of 1000 m. The robust ceramic measuring cell offers maximum overload and vacuum resistance, making it a highly reliable addition to any water treatment and distribution facility’s process automation arsenal.
