Step 2. welds a Hall sensor (3) on sampling plate I (61) and sampling plate II (62) first, then will sampling
Plate I (61) and sampling plate II (62) are respectively and fixedly installed to the two sides of shell (13), specifically: sampling plate I (61) is mounted on shell
In groove (16) on body (13), sampling plate II (62) is mounted on opposed with side wall where groove (16) on shell (13)
Hall sensor (3) on one side wall, and on sampling plate I (61) and sampling plate II (62) is inserted into groove body (12) and close
Character wheel (21) is equipped between the Hall sensor (3) on Hall sensor (3) and sampling plate II (62) on sampling plate I (61)
Angle；
Step 3. passes through the power supply VCC pin on sampling plate I (61) on 66 polyvinyl chloride insulation black lines and sampling plate II (62)
The connection of power supply VCC pin, the ground connection GND pin on template I (21) passes through 66 polyvinyl chloride insulation black lines and sampling plate II
(62) the ground connection GND pin connection on；
The input/output interface of step 4. counter is formed using 4P low-frequency connector, i.e. sampling plate I (61) and sampling plate II
(62) it is connect by 4P low frequency connecting line with control module, one end of 4P low frequency connecting line is connect with Hall sensor (3), and 4P is low
The other end of frequency connecting line is connect with control module；
The ventilation of step 5. gas meter, flow meter drives driving wheel (22) rotation, and driving wheel (22) driving character wheel (21) is rotated and measured,
When the effect for turning to Hall sensor (3) on sampling plate I (61) and sampling plate II (62) with the magnet steel embedded on character wheel (22)
When range, Hall sensor (3) has high level to become low level, forms a pulse signal, passes through the defeated of 4P low-frequency connector
Exit port is transmitted to control module, completes sampling.
