図1において、1はガスメーターに内蔵され、ガスを用いて発電を行い、それにより得られた電力を外部に供給可能な燃料電池である。2はガス流動方向上流側と下流側とに所定の間隔をおいて少なくとも一対の超音波送受信器を配置し、それら超音波送受信器間の超音波伝搬時間をもとにガス流量を検出を行うガス流量検出器、3は上記燃料電池1の電力出力検出及び積算と、ガス流量検出器2のガス流量検出及び積算を行う制御部、4は燃料電池1における電力出力検出と積算値、及び前記ガス流量検出器2におけるガス流量検出と積算値をそれぞれ表示する表示手段である。表示手段は、5は表示手段4による表示を、燃料電池1による電力出力検出の積算値、或いはガス流量検出器2によるガス流量検出の積算値のいずれかに切り替える表示切替手段である。
(Embodiment)
In FIG. 1, reference numeral 1 denotes a fuel cell that is built in a gas meter, generates power using gas, and can supply the electric power obtained thereby to the outside. 2, at least a pair of ultrasonic transmitters / receivers are arranged at a predetermined interval on the upstream and downstream sides in the gas flow direction, and the gas flow rate is detected based on the ultrasonic propagation time between the ultrasonic transmitters / receivers. The gas flow rate detector 3 is a control unit that performs power output detection and integration of the fuel cell 1 and the gas flow rate detection and integration of the gas flow rate detector 2, and 4 is the power output detection and integration value of the fuel cell 1. It is a display means for displaying the gas flow rate detection and the integrated value in the gas flow rate detector 2 respectively. The display means 5 is a display switching means for switching the display by the display means 4 to either an integrated value of power output detection by the fuel cell 1 or an integrated value of gas flow rate detection by the gas flow rate detector 2.

以上のように構成されたガスメーターについて、以下その動作、作用を説明する。   About the gas meter comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

まず、ガスメーターの制御部3は、常に燃料電池1を動作コントロールしながら電力出力検出及び積算と、ガス流量検出器2でのガス流量検出及び積算をしており、図2のように、表示切替手段4がガス流量表示側であれば、ガス流量の計量積算値を表示している。   First, the control unit 3 of the gas meter constantly detects and integrates the power output while controlling the operation of the fuel cell 1, and detects and integrates the gas flow rate in the gas flow rate detector 2. As shown in FIG. If the means 4 is on the gas flow rate display side, the measurement integrated value of the gas flow rate is displayed.

ここで表示切替手段5を燃料電池1の電力表示側にすると、の制御部3は、その時点での燃料電池の電力出力の積算値を表示手段4で表示する。このように表示手段4により、燃料電池1の電力出力の積算値を外部から容易に目視確認でき、ガス販売の課金時の利便性を高めることができる。   Here, when the display switching means 5 is set to the power display side of the fuel cell 1, the control unit 3 displays the integrated value of the power output of the fuel cell at that time on the display means 4. In this way, the integrated value of the power output of the fuel cell 1 can be easily visually confirmed from the outside by the display means 4, and the convenience at the time of charging for gas sales can be enhanced.

また、燃料電池1の電力出力の積算値とガス流量の積算値をひとつの表示手段4で表示できるように切り替えて表示することにより、一つの表示手段4を二つの表示に兼用することができる。   Further, by switching and displaying the integrated value of the power output of the fuel cell 1 and the integrated value of the gas flow rate so that they can be displayed on one display unit 4, one display unit 4 can be used for two displays. .

なお、制御部3は、燃料電池1の電力検出の積算値と、ガス流量検出器2のガス流量検出の積算値をあわせて記憶する不揮発性の記憶手段を有するものである。   The control unit 3 includes a nonvolatile storage unit that stores the integrated value of the power detection of the fuel cell 1 and the integrated value of the gas flow rate detection of the gas flow rate detector 2 together.

以上のように、本実施の形態においてはガス流量の計量情報を表示する表示手段と兼用で、燃料電池の電力出力の積算値を外部に表示することにより、容易に外部から確認することができ、ガス販売の課金方式の利便性をより高めることができる。   As described above, in the present embodiment, it is also used as a display means for displaying the measurement information of the gas flow rate, and can be easily confirmed from the outside by displaying the integrated value of the power output of the fuel cell to the outside. In addition, the convenience of the gas sales billing system can be further enhanced.

以上のように、本発明にかかるガスメーターは、ガス流量の計量情報表示手段を使い、燃料電池の電力出力の積算値をも外部に表示することにより、燃料電池の動作状況が容易に外部から確認でき、ガス事業者のガス販売の課金方式の利便性を高めることができるもので、複数の機能表示を必要とする機器への展開が可能である。   As described above, the gas meter according to the present invention uses the gas flow metering information display means and also displays the integrated value of the power output of the fuel cell to the outside so that the operation status of the fuel cell can be easily confirmed from the outside. In addition, it is possible to improve the convenience of the billing system for gas sales of the gas company, and it is possible to develop it to a device that requires a plurality of function displays.
