And side plates 24 and 25 that cover both side surfaces 6b and 6c of the side surface.

FIG. 5 is a principle view of the sensor 19 mounted on the mounting body 18. As shown in FIG. The display reel 41 is one of a plurality of display reels provided in the display unit 6.
This is a display reel for displaying the least significant digit, and is inserted through the shaft 42. On the display reel 41, “0”, “1”, “2”,..., “8”,
The numeral "9" is displayed, and a reflection piece 41a is provided.

The rotation corresponding to the gas consumption flow rate is transmitted to the lowest display reel 41 via a transmission means (not shown) provided in the gas meter 3. The display reel 41 in this embodiment is set so as to make one rotation for a gas consumption flow rate of 10 liters.

The sensor 19 mounted on the mounting device 1
Is a reflection type photointerrupter, and a light emitting element 43 for irradiating light to the object to be detected in the sensor 19 and a wiring 20 (see FIG. 1) every time light reflected from the object to be received is received. A light receiving element 44 for outputting a pulse signal corresponding to the ON / OFF state to the meter sensor unit is provided. For the light emitting element 43, a near infrared light emitting diode (GaAs) or the like is used, and for the light receiving element 44, a phototransistor or a Photodarin transistor is used.

The light emitting element 43 is always mounted on the display reel 41.
Is irradiated on the outer peripheral surface of the light emitting element. In the outer peripheral surface of the display reel 41, the outer peripheral surface other than the portion provided with the reflective piece 41a is configured to absorb or irregularly reflect light emitted from the light emitting element 43. Therefore, only when the reflecting piece 41a reaches the path of the light emitted from the light emitting element 43, the light emitted from the light emitting element 43 is reflected by the reflecting piece 41a and received by the light receiving element 44. At this time, the light receiving element 44 transmits a pulse signal indicating the ON state to the meter sensor unit. Display panel 41
When the reflecting piece 41a moves from the light path due to the rotation of the light, the light emitted from the light emitting element 43 is not received by the light receiving element 44, and a pulse signal indicating an off state is transmitted to the meter sensor unit. Therefore, each time the display reel 41 rotates once, the light receiving element 44 is turned on once, and a pulse signal indicating the on state is transmitted to the meter sensor unit. As described above, the display reel 41 is set so that the gas consumption flow rate makes one revolution at 10 liters. Therefore, a flow pulse signal of 1 pulse / 10 liter is sent to the meter sensor section. As described above, the sensor 19 includes the front plate 2
3 is provided at a position facing the outer peripheral surface of the display reel 41 for displaying the lowest digit of the plurality of display reels via the display hole 17, so that when the sensor 19 is mounted on the gas meter, the mounting body 18 must be mounted. By simply attaching the sensor 19 to the display unit 6, the sensor 19 can be accurately positioned and disposed at a predetermined position. Moreover, as described above, since the attachment piece 18 is provided with the locking piece 31 into which the projection 29 of the gas meter is fitted, it is possible to prevent the attachment body 18 from easily falling off the display unit 6 together with the sensor 19. In addition, the sensor 19 detects the gas supply amount by outputting a pulse signal each time the display reel 41 for displaying the least significant digit makes one revolution, so that it is not necessary to modify the existing gas meter, and the existing gas meter can be replaced. The sensor 19 can be easily mounted.

FIG. 6 is a schematic diagram showing the configuration of a system for centrally managing the gas consumption flow rate displayed on the display area 15 of the gas meter 3 at a remote place using the mounting device 1 on which the sensor 19 is mounted. FIG. In this embodiment,
Although only one gas meter 3 is attached to the meter sensor unit 51, signals indicating gas consumption flow from a plurality of gas meters can be actually transmitted to the meter sensor unit 51.

As described above, the flow rate pulse signal sent from the sensor 19 is sent to the meter sensor section 51 via the wiring line 20. The meter sensor unit 51 to which the flow pulse signal has been input displays a display signal corresponding to the flow pulse signal,
The data is sent to the remote display 53 via the line 52. The remote display device 53 has a display area 5 realized by a liquid crystal display device or the like.
4 and a function of displaying the consumed gas flow rate as a digital signal in the display area 54 in response to the display signal.

Therefore, in a place such as a factory where a large number of gas meters are provided, it is possible to centrally manage the information on the consumed gas flow rate displayed on each gas meter at one place. This enables more efficient safety management with a small number of people.

According to the present invention, since the mounting body 18 has a pair of side plates 24 and 25 formed by being cut off from the front plate 23 by the notches 26 and 27, the mounting body 18 is connected to the display section 6 of the gas meter. It can be easily attached to. Further, since the locking piece 31 into which the projection 29 of the gas meter is fitted is formed on the upper plate 28 of the mounting body, it is possible to prevent the mounting body 18 from easily falling off the display unit 6 together with the transmitter 19. The transmitter 19 is provided on the front panel 2 of the mounting body.
3 is provided so as to face the outer peripheral surface of the lowermost display reel 41, so that the transmitter 19 is arranged to face the outer peripheral surface of the display reel 41 simply by attaching the mounting body 18 to the display unit 6. This eliminates the need for positioning work when the transmitter 19 is mounted on the gas meter, greatly reduces the time and labor required for the mounting operation, and allows the transmitter 19 to be easily and securely mounted without modifying the existing gas meter. be able to.
