Ultrasonic gas meter based on shunt metering device

An ultrasonic gas meter based on a shunt metering device, comprising a gas meter casing, wherein

• a gas flow stabilizer for stabilizing a gas flow is provided in the gas meter casing;
• a middle of the gas meter casing is provided with a gas port for gas circulation;
• a middle of a cavity of the gas port is provided with an ultrasonic metering device for metering a gas;
• and an end of the cavity of the gas port is provided with a shunting plate for shunting the gas;
• the gas flow stabilizer comprises a first stabilizing assembly for blocking the gas and a second stabilizing assembly for cooperating with the first stabilizing assembly to block the gas;
• and
• the gas flow stabilizer further comprises a limiting assembly for supporting and limiting the first stabilizing assembly and the second stabilizing assembly;
• an end of the limiting assembly is provided with a third stabilizing assembly for cooperating with the gas to adjust an angle between the first stabilizing assembly and the second stabilizing assembly;
• and a rotating assembly is provided in the limiting assembly and is configured to cooperate with the third stabilizing assembly to control the second stabilizing assembly to rotate.
