ABSTRACT:
A liquid flow monitor. The device includes a thermistor placed in the path of liquid flow. A circuit including the thermistor in a Wheatstone bridge is used to sense the liquid flow by sensing the change in resistance of the thermistor. A transistor connected to the bridge is used to maintain the thermistor within predetermined levels to prevent overheating of the device.
