Water Conservation Day is an international awareness day that aims to educate people about the importance of water conservation and responsible water usage. Understanding how to read a water meter is one way to monitor and control monthly water usage, save costs, and contribute to environmental sustainability.
1. Learn about water meters
What is a water meter?
A water meter, also known as a water flow meter or pressure gauge, is a device used to measure and record the flow of water in and out of a system over a specific period of time. The meter displays this information through numerical readings on its face.
Structure of a water meter
A water meter consists of three main components: the meter body, the display for measured values, and the number counter. The meter’s working principle involves the rotation of a wheel due to the flow of water, which is transmitted to the number counters to provide accurate readings.
2. How to read a water meter
How to read a 4-digit water meter
A 4-digit water meter has four black boxes displaying the water volume in cubic meters (m3) and three circular hand dials. The reading is done by recording the values in the black boxes from left to right. The hand dials indicate the water flow and trigger the movement of the number counters.
How to read a 5-digit water meter
A 5-digit water meter may have two types of displays. The first type has five black digits indicating the water volume, and the reading is done from left to right. The second type has four black digits and one red digit, where the red digits indicate the liter index. The black digit sequence represents the water volume, and it should be read from left to right.
How to read a 6-digit water meter
A 6-digit water meter consists of four black boxes representing the cubic meter of water and two red boxes indicating the liter measurement. When the red digits display the number 99, it signifies that it is nearing 1m³, and the black digit in the cubic meter place will increase by one when it changes from 99 to 00. Only the black digit sequence needs to be recorded when determining water consumption.
How to read a 7-digit water meter
A 7-digit water meter has five black digits representing cubic meters of water and two red digits indicating the liters of water. The cost of water is calculated based on the cubic meter reading.
How to read an 8-digit water meter
8-digit water meters come in two types. The first type has five black digits and three red digits, while the second type has four black digits and four red digits. For both types, only the black digit sequence needs to be recorded when determining water consumption.
3. How to accurately calculate household water costs
To calculate accurate household water costs, it is necessary to refer to the state’s pricing table in addition to considering usage needs, purposes, and objects. The monthly cost can be calculated by summing the costs from different usage tiers.
This article provides a comprehensive guide on how to read a water meter. By understanding the process, individuals can easily monitor their monthly water consumption and contribute to water conservation efforts.
