- Measurement of unit water quantity by current harmonics (synthetic wave of more than two waves)
- Current (alternating current) between electrodes is converted to the unit water quantity through modulation of high frequency on low frequency
-Improvement of accuracy by change of the 1st and 2nd polarity. Measurement is possible in the container without having to sort out fresh concrete aggregate (separate vibration screen is not required)
- Precision balance is not required as weight measurement is not needed for the measurement
- Stores measurement data and printing is possible through infrared communication
