摘要： PROBLEM TO BE SOLVED: To provide a gas meter which reduces a power consumption used to drive an adjusting means by a method wherein the position (the opening amount) of a valve is controlled properly according to the used amount of gas.
SOLUTION: The gas meter is provided with a main flow channel in which the adjusting means used to adjust the opening amount of a flow channel is installed, a subflow channel which bypasses the adjusting means in the main flow channel, a flow-rate detection means and a control means which controls opening/closing of the adjusting means on the basis of a corrected flow-rate value obtained by correcting and processing the detected flow-rate value of the flow-rate detection means. The control means controls the adjusting means to the position of a first opening between a fully closed position and a fully opened position when the corrected flow-rate value becomes a first prescribed flow-rate value or more, and it controls the adjusting means to the fully opened position when the corrected flow-rate value becomes a second prescribed flow- rate value or more higher than the first prescribed flow-rate value when the adjusting means is in the position of the first opening.

摘要： PROBLEM TO BE SOLVED: To provide a gas leak detector or a gas meter which reduces the driving number of times of an adjusting means to reduce the current consumption of a battery for driving the adjusting means and reliably detects even a small rate of gas leakage.
SOLUTION: The gas leak detector or the gas meter having this detector comprises a main passage having a means for adjusting the opening of the passage, a subpassage having a flow rate detecting means, and a failure detecting means. The subpassage bypasses the main passage. The failure detecting means controls to fully close the adjusting means in the event of a failure detected, and the adjusting means detects the gas leak failure, based on a measured value by the flow rate detecting means with the adjusting means fully closed. The detecting means acts for detecting the failure every first specified time. If the detected flow rate based on the measured value by the flow rate detecting means with the adjusting means fully closed in the event of the failure exceeds a first specified flow rate continuously for over a second specified time, it detects the gas leak failure.

摘要： PROBLEM TO BE SOLVED: To reduce pressure losses due to the forward movement in a bent state of gas toward a relay chamber from a gas inlet via a valve chest by changing the concept that a gas inlet and a valve chest are sufficiently formed in such a way that two cylindrical metal molds may be butted to each other in a shape intersecting each other at right angles and casted.
SOLUTION: A gas meter is provided with both the longitudinally oriented gas inlet in an outside part of an upper lid in a width direction and the valve chest for feeding gas forward immediately below the gas inlet. A rear end part of the valve chest is closed by a check plate for an isolation valve, and a front end part of the valve chest has a valve seat. A valve plate for pressing valve rubber to the valve seat is arranged on the rear surface side of the valve rubber to be in tight contact with the valve seat to form a valve element. The valve element is arranged separately from the valve seat immediately below a cylindrical space in the gas inlet in a plan view at the use of gas, and the valve element is in tight contact with the valve seat at the time of abnormalities in the gas meter. A recession part for partially enlarging the opening diameter of the valve chest is formed at least inside the valve chest in a width direction more forward than a rear surface of the valve rubber in a boundary part between the gas inlet and the valve chest.
