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 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.

No-Guide-Rail Design

No-Guide-Rail Design

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

PSU Body Material for Chemical Solutions

PSU (Polysulfone), which is acid, alkali, and electrolyte resistant, suitable for chemicals like sulfuric acid and sodium hydroxide, etc.

Unique Turning Machined Fittings, Smooth Insertion Installation

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!

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.

⚠️ Important Notice Before Ordering
  • Liquid flow data is based on tests with clean water at 20°C; gas flow data is based on air at 0°C under 1 atmosphere of pressure.
  • This is a rail-less flowmeter. Due to design considerations related to specific gravity, the float material is fixed according to the flow range and cannot be replaced.
  • To ensure product quality, all items are manufactured under ISO 9001 procedures. Same-day or next-day delivery and on-site pickup services are not available. We apologize for any inconvenience.
  • As application conditions vary widely across industries, please select the appropriate model based on your actual needs. The temperature and pressure resistance data listed above are for reference only and may not apply to all environments. If you have any questions, feel free to contact our sales team.
