[0001] The utility model relates to flow measurement technical field especially relates to a kind of electromagnetic water meter of quick replacement antenna. BACKGROUND

[0002] With the evolution of the times, scientific and technological continuous updating, the transmission mode of information data is also constantly optimized and improved. Traditional cable connection transmission mode is gradually replaced by wireless electromagnetic wave transmission. Compared with cable connection mode, wireless transmission not only has lower comprehensive cost, more stable performance, but also has flexible networking, superior scalability, and realizes the convenience of plug and play. The electromagnetic water meter equipped with wireless remote transmission function is combined with remote monitoring and management software system, which can realize the reception and storage of flow meter data, and statistically analyze the flow data, so as to conveniently and quickly master the water consumption of each flow measurement point in the region.

[0003] At present, the electromagnetic water meter with remote transmission function is composed of communication component and basic measurement meter, and two parts occupy one cavity respectively. The remote transmission assembly of traditional water meter is divided into two types: built-in antenna type and external antenna type. In the built-in antenna type, the antenna for signal transmission and the communication assembly are in the same cavity. This design is easily affected by geographical environment factors, which may cause signal transmission failure or significant delay, limiting the real-time update of data. In contrast, the external antenna type connects the antenna for signal transmission to the higher open area through cable. The essential difference between internal and external antennas is the length of the distance between the communication antenna and the basic measurement meter. Whether it is external antenna or internal antenna, the traditional water meter has two cavities to protect and protect the measurement components and communication components. For traditional electromagnetic water meter, once out of the factory, the external antenna type and the internal antenna type cannot be flexibly converted.
