放水量制御装置。[Scope of Claim for Utility Model Registration] (1) A transmitting unit that compares a signal from a flowmeter that detects the pump flow rate with a signal from one or more transmitters that generates a reference flow rate signal and generates a drive signal according to the difference between the signals. a nozzle operation box equipped with an on/off switch for activating the transmitter; and a cable buried in the hose and connecting the on/off switch and the transmitter to form an ON-OFF circuit. A water discharge amount control device for fire engines, etc. (2) a first transmitter that compares a signal from a flowmeter that detects the pump flow rate with a signal from one or more first transmitters that generates a reference flow rate signal, and generates a drive signal according to the difference; A pump drive control comprising: a second transmitter that compares a signal from a second transmitter that selectively issues either an increase or decrease signal with the drive signal and issues a new drive signal according to the difference; a nozzle operating box having an on/off switch for activating each of the first transmitter and the second transmitter;
and a cable that connects a second transmitter to form an ON-OFF circuit.
