1. What is the primary function of a water meter?
A. To increase water pressure
B. To measure the volume of water used
C. To purify water
D. To store water
Rationale: A water meter is designed to measure the amount of
water passing through a pipeline to a consumer.
Correct Answer: B. To measure the volume of water used
2. Which unit is commonly used to measure water
consumption in residential meters?
A. Kilograms
B. Liters per second
C. Cubic meters
D. Pascals
Rationale: Water consumption is typically measured in cubic
meters or gallons.
Correct Answer: C. Cubic meters
,3. What type of meter uses a spinning disc or piston to
measure flow?
A. Magnetic meter
B. Positive displacement meter
C. Ultrasonic meter
D. Venturi meter
Rationale: Positive displacement meters measure water by
trapping fixed volumes.
Correct Answer: B. Positive displacement meter
4. What is the main purpose of meter calibration?
A. Increase water pressure
B. Ensure accurate measurement
C. Reduce pipe size
D. Clean the water supply
Rationale: Calibration ensures the meter reads flow accurately
within acceptable limits.
Correct Answer: B. Ensure accurate measurement
5. Which component protects a water meter from debris?
A. Valve
B. Strainer
,C. Pump
D. Regulator
Rationale: Strainers remove debris before water enters the
meter.
Correct Answer: B. Strainer
6. What is a typical cause of inaccurate water meter readings?
A. High water purity
B. Air in the pipeline
C. Low temperature
D. Excess pipe length
Rationale: Air pockets can cause meters to over-register usage.
Correct Answer: B. Air in the pipeline

Rationale: Turbine meters are suitable for high flow rates in
industrial systems.
Correct Answer: B. Turbine meter
, 8. What does a backflow condition refer to?
A. Water flowing forward normally
B. Reverse flow of water into the system
C. Increase in pressure
D. Water leakage outside pipes
Rationale: Backflow is the unwanted reverse flow of water.
Correct Answer: B. Reverse flow of water into the system
9. Why is sealing important in water meters?
A. To improve flow rate
B. To prevent tampering
C. To increase water pressure
D. To reduce cost
Rationale: Seals prevent unauthorized access or meter
manipulation.
Correct Answer: B. To prevent tampering
