M13 requires no water shutdown during installation or maintenance, ensuring uninterrupted supply—ideal for ret-rofitting critical systems.
M13 also eliminates on-site welding, reducing time, safety risks, and water contamination, making them ecient for high-hygiene applications.
The crosshair-equipped viewing window is critical for measurement accuracy, providing a visual reference to align the insertion rod’s depth and ensure initial position- ing precision, thus avoiding velocity sampling and flow calculation errors caused by improper insertion.
The adjustable base adapts to uneven surfaces or pipeline orientations by adjusting vertical alignment and horizontal parallelism, stabilizing positioning and optimiz- ing the insertion rod’s alignment with the pipeline’s internal flow path to reduce measurement discrepancies.
Two fixing bolts lock the insertion rod at a consistent depth, preventing displacement from water pressure or vibrations.
The safety rope acts as a fail-safe, securing the rod against sudden ejection to protect equipment and install ers, ensuring long-term measurement stability.
M13 integrates a pressure sensor with a non-protruding design, minimizing damage during transportation/installation.
One-time setup enables simultaneous flow and pressure monitoring, enhancing eciency while reducing costs and space usage.
M13 incorporates an external lithium battery, enabling standalone operation without external power dependence. Engineered for durability, this battery delivers a service life exceeding 6 years for compact meter and 7 years for remote version with one battery pack (with 9-second measurement intervals and 6-hour upload cycles).
Ideal for locations lacking reliable power infrastructure, it allows seamless installation in remote or o-grid sites.
For models with hybrid power supply, the battery acts as a dependable backup, ensuring continuous operation during external power interruptions.
M13 enables timely reporting of potential measurement-impacting incidents, with rapid early warnings for proactive resolution, reducing trade settlement disputes and safeguarding both parties' interests.
Internal measuring components are also IP68 waterproofed, ensuring accurate measurements even if water ingress occurs.
M13 employs 128-bit AES encryption for remote transmission data, eectively preventing illegal access or tampering during transmission and fully ensuring data security.
Cable length for remote version of M13 reaches up to 100 meters, 10 times longer than conventional models. The extended length enhances installation flexibility, simplifying deployment and reducing post-installation inspection/- maintenance diculty.
