Multi-jet meter Semi-dry model ASN-EM-SD

The Aria Sanjesh ASN-EM-SD Multi-Jet Semi-Dry Dial Water Meter delivers R160 accuracy, low pressure loss, and stable performance. Designed for residential applications and urban water distribution networks, this meter can be equipped with AMR (Automated Meter Reading) systems, making it a practical and cost-effective solution for modern water consumption measurement.

The ASN-EM-SD operates on a multi-jet measurement mechanism, where the incoming water flow is divided into multiple jets to drive the measuring turbine. This design ensures uniform flow distribution and improves measurement accuracy across different flow rates. In this type of meter, the register mechanism is in indirect contact with the fluid, and its simple yet efficient structure provides stable operation and easy maintenance under normal service conditions.

With its cost-effective design, reliable accuracy, low pressure loss, and compatibility with remote reading systems, the ASN-EM-SD is well suited for water consumption measurement in residential applications and urban distribution networks.
