D-FL200 Volume flow measuring system

Measuring system for ultra-sonic measuring of velocity and volume flow, especially for wet and aggressive smoke emissions (waste incineration).

■ Features

    ● In-situ measuring method

    ● Measurement possible below dew point and for high dust concentrations

    ● Continuous measurement of normal volume flow and gas velocity

    ● Automatic zero point and reference point control

    ● Direct connection for temperature and pressure correction

    ● Parameter input via keyboard or PC

    ● Continuous temperature measuring.

■ Applications

    ● Volume flow measuring at low speeds

    ● Plans with damp and/or aggressive exhaust gas, e.g. in waste incineration plants.

    ● Volume flow measurement at high dust content.

■ Approvals

    ● Suitability-tested by the TUV Hamburg, test report 99CU019

    ● Itemized in the list of suitable measuring devices for continuous emission measuring

    ● MCERTS pending.

■ Measuring principle

The D-FL 200 measuring system works according to the acoustic transit time differential method. Ultrasonic transducers mutually send and receive short pulses with and against the gas flow direction which affects their transit time. The volume flow is calculated from the difference of transit times.

■ Options

    ● Modbus interface

    ● Temperature transducer

    ● Absolute pressure transducer

    ● Weather protection covers

    ● Purge air sensor with potential free error contact.
