• What is the primary function of a water meter?
• To store water
• To measure water pressure
• To measure water consumption
• To filter water

Rationale: A water meter is installed to record the volume of water

consumed by a customer.

• Which tool is commonly used to remove a meter from a meter box?
• Pipe cutter
• Meter key 1 / 4

• Wrench
• Screwdriver

Rationale: A meter key is specifically designed to operate the valves

and remove water meters safely.

• What type of meter uses a magnetic field to measure water flow?
• Positive displacement meter
• Compound meter
• Magnetic flow meter
• Turbine meter

Rationale: Magnetic flow meters measure flow by detecting the

voltage generated by water moving through a magnetic field.

• What is a common cause of a water meter running slow?
• High water pressure
• Debris in the meter
• New meter installation
• Empty pipes

Rationale: Debris can obstruct the measuring mechanism, causing

the meter to under-register flow.

• Which component of a positive displacement meter measures the

volume of water passing through it?

• Measuring chamber
• Magnetic coil
• Turbine wheel 2 / 4

• Impeller

Rationale: The measuring chamber in a positive displacement meter

captures and measures discrete volumes of water.

• What safety measure should be taken before opening a meter lid?
• Wear gloves only
• None required
• Ensure the valve is closed and pressure is relieved
• Remove the meter key

Rationale: Opening a meter under pressure can cause injury; always

close valves and relieve pressure.

• Which type of meter is most accurate at low flow rates?
• Turbine meter
• Compound meter
• Positive displacement meter
• Ultrasonic meter

Rationale: Positive displacement meters maintain accuracy even at

very low flow rates, unlike turbine meters.

• What does a compound water meter combine?
• Magnetic and ultrasonic measurement
• Two measuring elements for high and low flows
• Water and gas measurement
• Turbine and electromagnetic technology 3 / 4

Rationale: Compound meters use a combination of meters to

measure both low and high flows accurately.

• How often should a standard residential water meter be tested for

accuracy?

• Every year
• Every 3 years
• Every 5–10 years
• Only when replaced

Rationale: Routine testing ensures accuracy over time, typically every

5–10 years depending on local regulations.

• What is the main advantage of an ultrasonic water meter?
• Easy to repair
• No moving parts
• Works only with clean water
• Measures pressure

Rationale: Ultrasonic meters use sound waves and have no moving

parts, reducing maintenance needs.

• What is “register creep” in a water meter?
• A broken dial
• Frozen meter
• Meter continues to register flow when water is off
• Valve leak
