As an improvement, a T-shaped silica gel sleeve is arranged in the waterproof cap, the T-shaped silica gel sleeve is sleeved outside the signal line, and a through hole for allowing the signal line to pass through is formed in the T-shaped silica gel sleeve.

As a further improvement, a groove is formed in the contact interface of the waterproof cap and the probe seat, and the waterproof sleeve sealing ring is arranged in the groove.

As an improvement, the copper joint comprises a first joint and a second joint, the inner diameter of the second joint is larger than that of the first joint, the outer walls of the first joint and the second joint are respectively provided with threads, and the copper joint sealing ring is arranged at the joint of the first joint and the second joint.

Due to the adoption of the technical scheme, the beneficial effects of the utility model are that:

the utility model provides a dual track ultrasonic flowmeter probe sets up waterproof component in the signal line outside of drawing forth through the oral area at the probe seat, and it is inboard to have avoided water to enter into the probe, has realized that the whole of probe is waterproof, and this dual track ultrasonic flowmeter probe waterproof performance is good, even install under open air or the abominable condition of environment, can not intake yet, has improved the security of using, and this structure easily dismouting, the change of the later stage probe of being convenient for, it is very convenient to use.
