[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Depend on Figures 1 to 5 The present invention discloses a heat meter with a separate metering module and a control module, comprising a metering module 1, a control module 2, and a protective box 3. The metering module 1 is installed on a pipe, and the control module 2 is installed inside the protective box 3. The metering module 1 and the control module 2 are connected by a first wire harness 4 and a second wire harness 5. The metering module 1 consists of a metering pipe 6, a temperature sensor 7, and a flow sensor 8. The temperature sensor 7 and the flow sensor 8 are both connected through the metering pipe 6 and are respectively connected to the first wire harness 4 and the second wire harness 5. An extension vertical pipe 9 is provided at one end of the top of the metering pipe 6, and a filter assembly 10 is provided inside the extension vertical pipe 9.

[0023] The metering module 1 and control module 2 are designed separately, and multiple control modules 2 are centrally located inside the protective box 3, which facilitates centralized meter reading by staff. At the same time, the protective box 3 can protect the control modules 2. The temperature sensor 7 and the flow sensor 8 can measure the fluid temperature and flow rate respectively.

[0024] The protective box 3 consists of a box body 11, a support frame 12, and a door 13. The box body 11 is fixedly connected to the top of the support frame 12, and the door 13 is connected to the front of the box body 11. The control module 2 is installed inside the box body 11. An X-shaped reinforcing beam 14 is welded inside the support frame 12. Several observation windows 15 are provided on the door 13. A sealing ring 16 is provided on the side of the door 13 near the box body 11. Several wire holes 17 that match wire harness 4 and wire harness 5 are provided on the box body 11.

[0025] The enclosure 11 and door 13 protect the control module 2, the observation window 15 allows staff to observe directly, the sealing ring 16 improves the sealing between the enclosure 11 and door 13, and the X-shaped reinforcing beam 14 strengthens the support frame 12 and improves the overall stability.

[0026] Flange plates 18 are welded to both ends of the metering pipe 6, which can be connected to the pipe.

[0027] The filter assembly 10 consists of a sealing cover plate 19, a support plate 20, and a filter screen 21. The sealing cover plate 19 is connected to the extension vertical pipe 9 by bolts. The support plate 20 is welded to the bottom end of the sealing cover plate 19. The filter screen 21 is welded to the bottom end of the support plate 20. Sealing gaskets 22 are provided on the sides of the support plate 20 and the filter screen 21 as well as on the bottom surface of the sealing cover plate 19.

[0028] The filter screen 21 can filter the fluid. When the filter screen 21 becomes clogged, the sealing cover 19 can be removed from the extension riser 9 to remove the filter screen 21 for cleaning. There is no need to remove the entire metering module 1 from the pipeline.

[0029] In operation, by separating the metering module and control module and centrally housing multiple control modules inside the protective box, the convenience and efficiency of meter reading for staff are improved, reducing their workload. The protective box also provides sun and rain protection for the control modules, extending their lifespan. Furthermore, the filter assembly, consisting of a sealing cover, support plate, and filter screen, filters the fluid within the pipeline, facilitating regular cleaning of the filter screen without requiring the entire metering module to be disassembled.
