Description	A new parallel plate capacitance sensor consisting of two metal sheets was built. The sensor - capacitor and the whole oscillating circuit was driven at 27 MHz frequency. Dynamic laboratory experiments were performed with grass from natural meadow in order to evaluate the possibility of forage mass flow determination by means of this sensor. The results showed that there was a relatively strong linear relationship between the feed rates of wet forage crop material passing through the sensor between its plates and measured capacitance sensor circuit output frequency. The coefficients of determination (R2) varied from 0.9 to 0.96. Further improvement of electronic circuit connection and further investigation of the sensor can be recommended.
