PA Energy, a London based energy and water services company, was asked to review the metering in three blocks at the hospital, whilst identifying any problems with heat and chilled water metering and provide a resolution fix. 

Heat metering requires three values; the flow rate, the temperature of the supply heat transfer fluid (usually water) and the temperature of the fluid in the return leg of the system.  These values can calculate the energy consumption which can be reviewed and savings potentially made. It was on the LTHW (low temperature hot water) system that PA Energy required a reliable flowmeter to measure the flow rate of the water up to 80°C at flow rates of between 5 and 8.5m3/h. It decided on the OPTIFLUX 2000 electromagnetic flowmeter from KROHNE. 

Designed for water and wastewater applications the OPTIFLUX 2000 provides both high accuracy and reliability and is maintenance free. It comes with a wide range of industry approvals and with a huge installed base, it gave PA Energy confidence that it was installing a meter it could trust. 

Percy Albuquerque, managing director of PA Energy comments; “Installing the correct flowmeter on a project is vital. We need to be confident that it can meet the demands of the application and provide accurate and reliable data readings that can be used in calculating energy consumption.” He continues, “KROHNE offered a solution that ticked all the boxes. We have now installed a number of  OPTIFLUX 2000 flowmeters and are very happy with how they are performing.” 

The systems provided by PA Energy, using the OPTIFLUX 2000 will enable the site staff to monitor utility consumption and evaluate demand whilst identifying opportunities for cost savings and carbon reduction.
