  • The Fundamentals of the Air Sampler Calibration-Verification Process

    INTRODUCTION The calibration of an air sampling instrument using a reference air flow calibrator requires attention to scientific detail in order to establish that the instrument’s reported values are correctly stated and valid under the actual operating conditions of the air sampling instrument. DEFINITIONS For the purposes of this ...

  • Online flow measurement

    Background The undershoot weir in Hohensaaten was built in 1913. It has three openings and regulates the discharge from the Oderbruch and from the Finow canal into the Hohensaaten-Friedrichsthaler-waterway. Moreover, it protects parts of the Oderbruch against Oder floods. The weir controls the waterlevels in the Havel-Oder-waterway and in the reach of Niederfinow- Hohensaaten. ...

  • Flow metering with MaxxFlow HTC - Case Study

    Application An important part of the production of cement is the processing of raw meal in the cyclone dust heater. During this process cement meal is heated by an airstream. Thereby CO2 is extracted from the cement. At the beginning of this process raw meal is stored in a silo, from where it is discharged via an air slide into a bucket elevator. The bucket elevator ...

  • Proposed Standard Test Method for Measurement of Pneumatic Permeability of Partially Saturated Porous Materials by Flowing Air

    This proposed standard describes a laboratory test method for the measurement of the coefficient of permeability for airflow (pneumatic permeability) through porous media (e.g., soils) partially saturated with water. Control and measurement of the airflow is effected at the inlet of the specimen. The permeameter cell is fitted with dual transfer lines that isolate the specimen pressure drop from ...

  • Tech update: Plant instrumentation - food engineering

    Sensors and other devices are the foot soldiers in automation architecture, but most food and beverage manufacturers still are looking for full value. You know an equipment category has arrived when it starts getting its own industry-specific center. For the food production sensors that do the heavy lifting in instrumentation technology, that day could arrive earlier rather than ...

  • Reporting and exchanging air quality information using e-Reporting

    A number of EU legal instruments require EU Member States to monitor and report air quality data. This information is collated, analysed and disseminated by the European Environment Agency (EEA). At present much of the data is reported electronically by countries in data flows required under a specific legal instrument. As a result, reporting on air quality is not always integrated across all ...
