Instrumentation is a critical component in water and wastewater treatment plants since the measurement and control of the various processes determines the quality of the water consumed, recycled or discharged into the sea. One such critical instrument is the magmeter (electromagnetic flowmeter) which is commonly used to measure instantaneous and cumulative water flow in water and wastewater treatment plants.
Increasingly stringent environmental and health and safety legislation requires high quality drinking water in taps and non-polluting wastewater that is adequately treated prior to discharge. Magmeters play a vital role in any water or wastewater treatment plant's operation and therefore the selection of a suitable model is critical.
Many factors influence the selection of an appropriate magmeter. A clear appreciation of the important characteristics and an understanding of the qualities of current models is required. These factors include transmitter housing, performance in demanding environments, accuracy at low flow velocities, earthing, empty pipe detection and the availability of service tools. The innovative Promag range of magmeters available from Endress+Hauser meets all the criteria and offers additional features and benefits.
Magmeters ensure that measurements are not affected by temperature, pressure or viscosity. These products contain no moving parts and can be utilised to measure highly contaminated liquids, sludge, and entrained solids thus making them ideal for deployment in mining, chemical, pulp and paper, and water and wastewater applications. The magmeters are cost effective, maintenance costs are low and the range offers a high degree of measuring dependability and long term stability.
