An outflow guide facing the nozzle for forcibly dissipating the droplets flowing out from the nozzle when the droplets grow to a certain size. A droplet counting system, characterized in that it is further provided with means for observing the growth and disappearance of droplets between the nozzle and the outflow guide and emitting a waveform signal, and means for calculating a flow rate from the waveform signal. Flowmeter. 2. To detect the growth and disappearance of droplets between a nozzle and an outflow guide by electrical continuity using a liquid junction (Request for registration of a utility model in which the nozzle and outflow guide are used as electrodes and both are connected to a detection part) The droplet counting type flowmeter described in item 1. 3. Practical use in which the presence or absence of a liquid junction due to the growth and disappearance of droplets is captured as a pulse signal, and the flow rate is calculated by counting the number of pulses per unit time. A droplet counting type flowmeter according to claim 2 of the patent registration claim. 4. A clock mechanism is incorporated in the detection part, and a droplet that grows and disappears is used as a switch, and a clock is set while the droplet switch is ON or OFF. The second claim for utility model registration is to calculate the flow rate by counting the number of pulses.
Droplet counting type flow meter as described in . 5. The droplet counting type flowmeter according to claim 1, which detects the growth and disappearance of droplets between the nozzle and the outflow guide by optical means.
