Answer :
Final answer:
The movement of the 0.1m³ dial during a gas meter dial test typically indicates normal gas flow, as it shows that gas is moving through the meter. The correct answer to what it indicates when the 0.1m³ dial moves during a dial test is (a) Normal gas flow.
Explanation:
When the 0.1m³ dial moves during a dial test on a gas meter, it usually indicates there is gas flow within the system. This is because the dial is designed to show the total volume of gas or water that has passed through the meter. If the dial is moving, this suggests that the gas is flowing through the meter as it should, confirming normal operation rather than a leak, a fault, or no flow at all. Therefore, the correct answer to what it indicates when the 0.1m³ dial moves during a dial test is (a) Normal gas flow.
When the 0.1m³ dial moves during a dial test, it indicates gas flow. This could be either normal gas flow or a gas leak, depending on the circumstances. If the dial moves significantly and there are no appliances or sources of gas usage in the area, it is likely a gas leak. However, if there are appliances using gas, it indicates normal gas flow.
