Outline
A digital manometer system that is robust against the change of temperature is developed. Difference of the temperature between measured pipes and the tube connecting conventional system to gas valve caused the incorrect judge of the leakage. In this system, pressure sensor is settled to gas valve directly without the tube.
Features compared with conventional system
- More reliable judge of leakage
- Smaller and lighter
- Better durability of the built-in printer
- More precise radiowave clock
