SANCHUAN supplies water meters for apartments and multi-unit residential projects, including mechanical, ultrasonic, prepaid and NB-IoT models. Each individual water meter records unit-level consumption for fair billing. A smart water meter for apartments can add remote reading, leak alerts and valve control, while wireless water meters for apartments support centralized data collection. Compare the options below by meter type, DN size, reading method and communication requirement, then request specifications or a project quotation.
| Project Requirement | Recommended Configuration | Current Models | Main Selection Point |
| Basic unit-level billing with low system complexity | Mechanical meter | LXSG-D3 | Confirm DN15–DN20, installation space, reading method and pulse-output requirement |
| Remote reading, leak alerts and valve control | Ultrasonic + NB-IoT meter | U540 / U550 | Confirm network coverage, protocol, platform integration and valve requirement |
| Pay-before-use billing | Prepaid card meter | LXSZK | Confirm top-up workflow, tariff rules, shut-off policy and billing integration |
Apartment sub-metering ensures fair billing—tenants pay for actual usage rather than shared estimates—leading to 15–30% reduced water consumption and enhanced leak detection when equipped with modern water meters for apartments. It also boosts property value, lowers operating costs, and aids in regulatory compliance by promoting accountability and sustainability.
SANCHUAN offers both mechanical water meter and ultrasonic smart water meter with individual unit monitoring. Ultrasonic models provide high precision, no moving parts, optional NB-IoT connectivity, and valve control. Mechanical types are durable and cost-effective. Both support pulse output and automated readings for tenant billing .
Project cost and payback depend on meter type, installation conditions, communication infrastructure and billing integration. Buyers should evaluate these factors against expected reductions in manual reading, billing disputes and leak-response time.
Choose mechanical models for cost-sensitive, no-network applications.
Opt for ultrasonic + NB-IoT to enable remote reads, leak alerts, and valve control.
Ensure size (DN15–DN20) fits your plumbing needs.
Check certifications (ISO/OIML/CE) for legal and trade compliance.
Consider scalability and integration with existing AMR/AMI/Billing platforms.
Confirm the number of units, pipe size, installation position, reading method, prepaid or postpaid billing, communication coverage and destination-market certification.
In apartments, a submeter (installed downstream of the main meter) measures each unit’s water usage independently. It tracks flow volume—mechanical meters via moving parts, ultrasonic via sound waves—and can transmit data automatically for tenant billing and leak detection
Water is measured in cubic meters (m³) or gallons. Submeters record total volume using mechanical registers or electronic displays. Smart meters often add pulse or wireless output for remote reading, enabling transparency and usage-based billing.
Select a model with a compatible communication option such as NB-IoT. Confirm network coverage, protocol, platform integration and whether valve control is required before ordering.
Integration depends on the meter output, communication protocol and the billing platform’s interface. Provide the existing platform or API requirements before quotation.
