Saving your resources – Our expertise for energy measurement solutions Rising raw material and energy prices are forcing companies to care for energy measurement more than ever. On this background, it is increasingly important to look at cost-effective, optimised usage of the existing resources. This situation calls for a more accurate measurement of the various energy fluids. Parameters such as temperature and pressure must also be considered as they affect energy efficiency. Only with the balancing of true mass flow rates, comparable figures are achieved that will provide effective...

To the perfect degree – Precise thermal energy control There is an increasing use of applications for the heating and cooling of industrial and office buildings. Buildings consisting of glass and concrete require an evacuation of the thermal energy. In addition, the cooling medium used for a building must be measured. The generation of cooling energy is an increasingly sought-after solution for cooling food, to support industrial processes (like server farms), or simply to provide comfort in a building. Due to the constantly increasing energy prices and the great efforts made to reduce the...

Retrofitted heat measurement Measuring the thermal energy of warm and hot water • No effect of (magnetite) scaling • Large dynamic range • Accurate measurement even at low demand in summer OPTITEMP temperature sensors • High measuring accuracy • Paired design When measuring the quantity of heat consumed in individual production areas (such as steam generators, CIP systems, heating circuit production or ventilation systems) both the flow rate of the heating water as well as the difference in temperature before and after each consumer must be precisely measured. The objective is to determine...

Keep things running – With retrofittet measurement equipment Often, there are situations when processes cannot be interrupted. In this case, clamp-on flowmeters can be used to retrofit heat and cooling measurement. With its robust industrial construction and regreasing concept, the OPTISONIC 6300 clamp-on flowmeter for liquids provides a revolutionary easy-to-handle solution. It can be fitted on the outside of pipes to measure the flow rate of liquids. Flow measurement can be performed anywhere and started immediately. In combination with two temperature sensors and a heat quantity...

Performance under pressure – Compressed air production and distribution Virtually every production operation has a compressed air network – but only in rare cases, these networks are monitored and adapted to reflect actual consumption rates. Costs can easily be reduced if the compressors used to provide the compressed air can be controlled against actual consumption. Even with energy prices under 10 cents per kilowatt hour, it is worth monitoring the compressed air system with measurement equipment as costs created by leaks or untapped output can easily run up into the five figure range...

Measuring the flow rates in the compressed air network The objective of measuring compressed air can be to determine consumption profiles and peak consumption to improve compressor monitoring. The measuring devices also detect leaks: if, for example, flow is being measured on a day off, this is a clear indication of a leak. For this purpose, the compressed air network is equipped with measuring devices in various points. Much thought has been put into which measuring method would be suited best to compressed air measurement in terms of the price-performance ratio. Test measurements were...

Measuring of FAD (free air delivery) of a compressor A Bureau of Energy Efficiency survey says that a flawless compressor with maximum efficiency can achieve 85 % of its rated efficiency. There are various factors affecting the efficiency such as oil filters, air filters, motor speed, and humidity at the inlet of the compressor and inlet filters. The reduction in efficiency due to the deterioration of the above parameters is 8–10 % (approx.). Hence it becomes extremely important to measure the FAD (free air delivery) of a compressor. It is defined as the amount of atmospheric air (free air)...

A hot topic – Steam production and distribution Every major production process, including pasteurisation, brewing, sterilisation, washing and cleaning requires steam or heating water. However, the supply of steam is extremely energy-consuming as the boiler is usually fired using liquid fossil fuels or natural gas. Accordingly, it is essential to have accurate measurements of the quantity produced in order to optimise burner control and, ultimately, operate the plant in an efficient and environmentally-friendly way. Boilers typically have an efficiency of 90 % to 92 %. However, looking at...

Measuring the flow rate of steam Many users assume that pressure and temperature conditions in all processes are always constant. However, fluctuations happen all the time and can cause significant measuring errors. With superheated steam – +190 °C; +374 °F/5 bar; 72.5 psi pressure – a pressure increase of just 1 bar; 14.5 psi will, for example, lead to a measuring deviation of 17.43 % due to density change. With a pipe size of DN 100 and energy costs of €60 per MWh, this means a yearly loss of over €200,000. Integrated Flowmeter with integrated pressure and temperature compensation Flow...

Measuring heavy fuel oil consumption Oil is one of the fossil fuels that are often used for producing energy or heat in various industries. Food processes, for example, need a lot of heat and steam for various processes such as pasteurization, drying, deep frying and cleaning along entire production process. To fire the required boilers, combined burners for coal and oil can be used. In order to start the combustion process and/or support the coal fire, oil is used for the booster and supporting burner. To get an ideal fuel ratio between oil and air, a precise mass measurement in the oil...
