Air-flow regulation for sewage treatment plants ·Precise ·Compact • Maintenance-free Clever messen.
Open the catalog to page 1Measurement and regulation of air for aeration tanks The precise regulation of the air quantities for the aeration tanks ensures not only the optimum sewage treatment process: The exact measurement and dosing of the energy-intensively compressed air saves cash and prevents the costly production of .,surplus" compressed air which is not really required for the optimum operation of the aeration tanks. deltafit increases the efficiency of the installation through demand-driven air conduction. lihe compact measl.lrement and control system saves energy costs and works maintenance-free over...

Open the catalog to page 3The deltaflow measuring principle Regulating precisely starts with the accurate mass f l ow measurement (actual value). The accurate and drift-free f low measurement is also a difficult measuring task in the practical operation of sewage treatment plants. • Optimum inlet conditions are not always possible. • The quality of the compressed air can be subject to humidity and contamination level and cause deposits in t he flow sensors. deltafit copes w ith all these problems: This air-flow measuring and control system uses the proven deltaflow pitot tube. Its high accuracy was tested several...
Open the catalog to page 4Comfortable software possibilit ies for the regulation drive systec Controls designs deltafit according to the individual process data and carries out the adjustments o f t lhe drive and the differential pressure transmitter. On the site, only the power supply and the setpoint need to be connected -finished. Inlet conditions Improve IT With the new lmproveiT database, it is possible to use t he deltaflow without any inlet sections. Even with strongly varying process data regarding temperature and pressure, the usual accuracy of 0.6% is obtained through the compensation of these influencing...
Open the catalog to page 5Flowmetering ,by systec" deltawave ·Ultrasonic multi meter for flow and flow profile The deltawave ultrasonic device is far more than a flowmeter for filled and(!) partially filled pipelines as well as open or closed channels: lt also determines very precisely the flow conditions in partially filled pipelines or du ring open-channel measurements. In an open flume, deltawave combines the ,normal" level measurement with the highly accurate multi-path transit time measurement and a revolutionary ultrasonic evaluation method. The deltawave electronics can be operated with up to 16 transducer...
