Description

Technical Field

[0001] The utility model relates to a split waterproof ultrasonic water meter, belonging to the field of flow measurement. Background Art

[0002] In the prior art, the ultrasonic transducers used in most ultrasonic water meters are only protected by epoxy resin potting, and the thickness of the potting is relatively shallow. No secondary protection is performed when they are assembled and used on the ultrasonic water meter. Their waterproof performance does not meet the requirements of long-term use in harsh environments. Ultrasonic water meters are prone to failure when used in harsh environments. Since the transducer is the core component of the ultrasonic water meter, its damage will cause the ultrasonic water meter to lose its metering function.

[0003] In the prior art, the metering part and the remote communication part of the remote ultrasonic water meter are integrated and powered by the same battery. When the remote communication part consumes high power due to problems such as poor signal, the battery is easily exhausted before the product service life. Based on the characteristics of the ultrasonic water meter, the water consumption cannot be measured and displayed after the battery is exhausted, which can easily cause water use disputes.

[0004] Similarly, since the metering part and the remote communication part of most remote ultrasonic water meters are integrated, when either the basic metering function or the remote communication function fails, it is necessary to stop the water supply to the pipeline and replace the entire water meter, which makes maintenance difficult and increases maintenance costs. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a split waterproof ultrasonic water meter in view of the above shortcomings. The metering function and the remote communication function are respectively used as separate functional modules, and the two functional modules are combined and disassembled conveniently. The ultrasonic water meter has good waterproof performance and is suitable for long-term use in humid and submerged environments.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A split waterproof ultrasonic water meter comprises an ultrasonic water meter measuring tube assembly, a metering module and a communication module, wherein the metering module is mounted on the ultrasonic water meter measuring tube assembly, and the communication module is fixed on the metering module;

A 1# O-ring is installed between the bottom shell and the ultrasonic water meter measuring tube assembly. The nut passes through the upper thread 2 of the compression screw sleeve and is tightened to compress the 1# O-ring to achieve sealing.

[0013] Furthermore, a module box is provided in the enclosed space A, and the circuit board of the metering module is placed in the module box. The module box is open, and potting glue is injected into the module box to wrap the circuit board, thereby ensuring the waterproof performance of the metering module.
