摘要： PROBLEM TO BE SOLVED: To provide an attaching structure with which a transmitter can be attached inexpensively and easily to a gas meter in a fine appearance taking a small space. SOLUTION: The attaching structure is used for attaching a transmitter 1 for introducing a centralized monitoring system utilizing a telephone line to a gas meter 2 through a bracket 4. The gas meter 2 is constituted so that each parts of the meter 2 can be fixed with screw tightening means 22 using screws and the bracket 4 is constituted so that the bracket 4 can be fixed to the meter 2 by utilizing the screw tightening means 22.

摘要： PROBLEM TO BE SOLVED: To simplify connection work, and to eliminate erroneous connection. SOLUTION: A gas meter 1 operated by a built-in battery is provided with a connection means 31 having a shape different from a terminal 26 of a terminal block 19 to connect an emergency electric power source when a voltage of the battery gets low, in the terminal block 19 of the gas meter 1. The connection means 31 is a connector, and has the same shape with an external connection terminal of a cellular phone. A damage of other external equipment caused by the erroneous wiring is prevented thereby. A connection work time for connecting the emergency power source to the connection means is shortened thereby, and the emergency power source for the gas meter is easily available without being provided all the time.

摘要： PROBLEM TO BE SOLVED: To provide a diaphragm type gas meter which can surely prevent float of slide valve from a valve seat when rotation of the slide valve is transmitted to a gas flow display means and even if a rotation transmitting means is broken down and the slide valve is forcibly floated. SOLUTION: This gas meter has a valve seat 3, a slide valve 4 turning by sliding on this valve seat 3 and performing supply and exhaust of gas to from bladder diaphragm 22, a link mechanism 5 for converting reciprocating movement of the bladder diaphragm 22 caused according to supply/exhaust of gas into rotational movement and transmitting it on a crankshaft 5d on the slide valve 4 and turning and driving the slide valve 4 and a rotation transmitting means (gear box) 9 disposed upward of the slide valve 4 and transmitting rotation of the slide valve 4 to a gas flow display means (counter) 11 through the crankshaft 5d and a first magnet 7 is disposed in an upper part of the slide valve 4 and a second magnet 8 is disposed in a lower part of the rotation transmitting means 9 in the direction repulsive to the first magnet 7.

摘要： PURPOSE:To facilitate the assembling without deforming or damaging an O-ring at the installation of a nozzle, in a structure in which the nozzle is installed in the opening part of the bulkhead of a case body, and these are sealed by a seal material such as the O-ring, and automatize the assembling. CONSTITUTION:In a gas emergency trip valve having a nozzle 28 installed to an opening part 31 formed on the bulkhead 30 of a case body to allow an inlet port side A of fluid to communicate with an outlet port side B, from the inlet port side A of fluid, the nozzle 28 is formed of a nozzle body 28a communicating with the opening part 31 and a flange part 28b provided on the nozzle body 28a, and an O-ring 35 is provided between the flange surface 28d of the flange part 28b and the surface of the bulkhead 30. The nozzle body 28a protruded from the position where the flange part 28b is provided toward the outlet port side B of fluid is inserted into the opening part 31, and a clearance 33 is formed between the outer circumferential surface of the nozzle body 28a in the insert part and the inner circumferential surface of the opening part 31.
