Special Advantages: Special Advantages: •Because the deltaflow is not sensitive tocondensation or pollution, it is the ideal metering tool for measuring sewage gases.•The deltaflow is designed for stability inlong-term use and is drift-free, making it particularly suitable for metering air flow.•deltaflow is useful for metering air, water,and steam in the sludge treatment and combustion industries. •The deltaflow’s high degree of precisionand accuracy increases the quality of your performance and your products•Your deltaflow can be made of materialssuited to especially corrosive or high-tem- perature media, thus providing a solutionfor your “problem areas.” Such as pyroly- sis, for example: the deltaflow can be manufactured from acid-resistant materi- als which can be installed for constant use in temperatures over 1200°C.•Neither vacuum nor high-pressure appli-cations are a problem; all transformersconform to ATEX standards and can be used at up to 690 bar. The deltaflow is especially valuable for me-tering biogases and sewage gases in the The deltaflow is also a viable solution in the —for metering products, exhaust or flue gasses, or inert or aggressive media. In a three-month endurance test conducted at Wacker-Chemie in Burghausen, Germany, the deltaflow proved its durability measur- ing 100% steam-saturated, aggressive and polluted flue gas. chemical and petrochemical industries
