Project Description
ISW1598 STS Integrated Keypad Prepaid Water Meter
ISW1598 Integrated Keypad Prepaid Water Meter is a type of utility meter that allows users to pay for water in advance, similar to a prepaid mobile phone plan. Instead of receiving a monthly water bill, customers pre-purchase water credits, which are loaded onto the meter. The meter deducts the credits as water is used. Once the credits are exhausted, the water supply is automatically stopped until more credits are purchased.
Key Features of Prepaid Water Meters:
1.Prepaid Usage: Users purchase water units in advance, giving them more control over their consumption and budget.
2.Digital Monitoring: These meters often include digital displays that show the remaining balance, water usage, and other information.
3.Automated Shut-Off: When the prepaid balance reaches zero, the water supply is cut off until the meter is recharged.
4.Smart Features: Some models integrate with mobile apps or online platforms for recharging and usage tracking.
5.Conservation: By making users more conscious of their consumption, these meters can encourage water conservation.
Benefits:
•Helps avoid unexpected bills.
•Encourages responsible water use.
•Reduces administrative costs for utility providers.
•Can be integrated into systems for monitoring water access in communities.
Applications:
•Residential households.
•Apartment complexes.
•Commercial properties.
•Rural or remote areas with limited utility management resources.
