Provided is a treatment liquid flow rate meter which is provided with a variety of functions and is easy to use, specifically a treatment liquid flow rate meter which measures the flow rate of treatment liquid flowing through a supply pipe (200) and comprises: a pair of ultrasonic vibrators (2, 3) arranged separated by a fixed distance in the direction of flow of the supply pipe (200); a flow rate calculation section (4) for calculating the flow rate of the treatment liquid based on a first arrival time (T1), which is the time an ultrasonic wave emitted from the first ultrasonic vibrator (2) arrives at the second ultrasonic vibrator (3), and a second arrival time (T2), which is the time an ultrasonic wave emitted from the second ultrasonic vibrator (3) arrives at the first ultrasonic vibrator (2); and a bubble ingress determination section (5) for determining whether or not bubbles are mixed in with the treatment liquid, based on the amount of temporal change in the calculated treatment liquid flow rate.
