1. What is CCW Usage Calculation?

CCW (Cold Circulating Water) usage calculation determines the amount of water consumed over a period by subtracting the previous reading from the current reading.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( Current \) — Current meter reading (m³)
• \( Previous \) — Previous meter reading (m³)

Explanation: This straightforward calculation provides the actual water consumption between two measurement points.

3. Importance of Usage Calculation

Details: Accurate water usage calculation is essential for monitoring consumption patterns, detecting leaks, managing resources efficiently, and calculating costs in industrial and commercial settings.

4. Using the Calculator

Tips: Enter both current and previous readings in cubic meters (m³). Ensure readings are from the same meter and represent sequential measurements.

5. Frequently Asked Questions (FAQ)

Q1: What if I get a negative usage value?
A: A negative value suggests the current reading is lower than the previous, which may indicate a meter reset, reading error, or meter malfunction.

Q2: How often should readings be taken?
A: Frequency depends on your specific needs, but typically readings are taken monthly for billing purposes or weekly for consumption monitoring.

Q3: What units should I use for the readings?
A: This calculator uses cubic meters (m³), which is the standard unit for water measurement in most systems.

Q4: Can this calculator handle decimal values?
A: Yes, the calculator accepts and calculates with decimal values for precise measurements.

Q5: What if the meter has been replaced between readings?
A: If a meter has been replaced, you'll need to account for the final reading on the old meter and the initial reading on the new meter to calculate accurate usage.
