Principle

The area flow meter calculates flow rates by equating the upward thrust of the fluid, caused by variations in pipe diameter cross-sectional area, with the force of gravity acting on the float from below.

Principle
Patented dual-indicator

Patented dual-indicator

From the user's perspective, LORRIC employs a dual-pointer design to monitor upper and lower limit intervals, enabling users to easily identify the flow status at a glance. Users can simply flick the pointer to instantly set the flow monitoring range.

Laser engraved degree scales

LORRIC precisely calibrates each flow meter at the factory to compensate for float weight variations, ensuring ultimate performance. Unlike competitors using mass printing or stickers, our laser engraving offers both accuracy and durability.

Chemicals vary in specific gravity, affecting float buoyancy. LORRIC offers tailored customization for specific gravity, eliminating the need for on-site height adjustments.

Delicate machining for float

LORRIC leverages 30 years of industry expertise, applying fluid mechanics to refine float design. Using precision CNC machining, each float is crafted with jewelry-like precision, guaranteeing stable monitoring for area flow meters.

The unique turning-processed joint, ensuring smooth installation and insertion

Don't settle for subpar joints! While most are injection-molded, resulting in uneven surfaces due to cooling shrinkage, LORRIC's original turning-processed joints offer unmatched quality. With a flawlessly smooth surface, O-ring seal for safety, and zero leakage, choose LORRIC for superior performance!

The flat joint surface ensures O-ring seal without leakage

Guide Rail Design

Guide Rail Design

The guide rail design effectively limits the movement of the float within the pipe, reducing turbulence-induced oscillation or rotation. This design enhances measurement precision by ensuring the float remains aligned along the flow meter's axis, contrasting with models lacking a guide rod which may lead to off-axis float movement and impact flow rate accuracy.
