Page 4 MGG/KL-DCB Portable Electromagnetic Velocity Meter I. Summary The MGG/KL-DCB series of electromagnetic velocity meter is portable instrument flow designed for the flow velocity/rate measurement. It’s professional for agricultural irrigation, hydrologic monitoring, rivers flow monitoring, municipal water. The low-power design and full digital signal processing technology make measurement more stable and reliable.
Page 5: Ⅳ Working Principle
 Measuring rod：Normal 500mm×Sections (500mm×optional sections) or lifting accessories. IV. Working principle The MGG/KL-DCB portable electromagnetic velocity/flow meter depends on the Faraday's law of electromagnetic induction. The conductive liquid cut the magnetic line and cause induced electromotive force when do the direction perpendicular to the magnetic field lines in the alternating magnetic field along the measuring pipe.

Modifing measuring time for example: Enter Setting/Modification, use “+/-” to page up and down, find the measuring time. Press “set” and there is white line under the time. Then use “+/-” to modify the parameter. After completion press “set” again to remove the cursor and the parameter setting will be saved at the same time.

signal output. Short measurement filtering time shows fast corresponding speed. Flow unit: Instantaneous flow divides m³/s and m³/h; Velocity digit: The display of converter is 3-digit for choice according to the need; Time: The velocity meter will sent average data within a certain period to display.This is measurement period.
Page 11 Conversion factor: This parameter is special factor of display manufacturer for unify the circuitry of display measurement. Ensure every display consistency(irrevocable parameter); Instrument factor: It it reserve factor, it shows product relationship with velocity; Model: Irrevocable parameter only for factory; Level range: Ⅲ-Model have water level measurement function.
