Rotameters

The area-type rotameter measures flow by balancing fluid buoyancy and float weight, ideal for direct flow observation. It requires vertical installation with fluid flowing bottom to top. Reading the float position varies by model. Widely used in chemical, pharmaceutical, and food processing industries to monitor liquid or gas flow.

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 rotameter 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.

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 rotameter's axis, contrasting with models lacking a guide rod which may lead to off-axis float movement and impact flow rate accuracy.

PC for Water, PSU for Chemical Solutions

The flow meter body is available in two materials: transparent PC (Polycarbonate) for tap water, and light yellow PSU (Polysulfone), which is acid, alkali, and electrolyte resistant, suitable for chemicals like sulfuric acid and sodium hydroxide, etc.

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 rotameters.

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

Rotameter 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.
