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.

Flowmeter scale customization

Flowmeter scale customization

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

Unique Turning Machined Fittings, Smooth Insertion Installation

Don't settle for the struggles of traditional intubation joints. LORRIC's innovation brings you turning-processed joints with a specially designed pipe wall, ensuring a silky-smooth installation experience. Say goodbye to tight fits and hello to effortless installation!

Unique Turning Machined Fittings, Smooth Insertion Installation
Flat Contact Surfaces on Fittings, Paired with Oring for Leak-Proof Assurance

Flat Contact Surfaces on Fittings, Paired with Oring for Leak-Proof Assurance

Most market-available fittings are injection molded, leading to wavy surfaces due to cooling shrinkage. LORRIC uniquely produces fittings by turning, resulting in a smooth surface without depressions, paired with an Oring seal for a worry-free, leak-proof experience.

 

No-Guide-Rail Design

The float is made of special materials, particularly suitable for solutions corrosive to metals and environments requiring high chemical resistance.

Three easy steps! Effortlessly install the rotameter!

Step1
Step1

Ensure the main line is vertically installed and that there is ample space to accommodate the flow meter size.

Step2
Step2

Loosen the upper and lower interfaces, including the nuts, and affix them to the pipe using adhesive until the glue sets.

Step3
Step3

Position the body in the center and secure the upper and lower unions.
