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

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.

Guide Rail Design

Guide Rail Design

The drawback of float variations due to pipeline turbulence is mitigated by the constraints of the guide rail, which reduces the freedom of movement of the float. This results in more accurate measurements than flow meters without guide rails.

Patent Magnetic Pointer Design

Suitable for monitoring the flow of dark liquids, the patented magnetic pointer design ensures easy installation without leaks, easy adjustment, and precise positioning. The stable flow field, dual pointer design, and laser-engraved scales make flow monitoring more convenient. The connection can be changed to a flange type for increased durability and safety, extending the lifespan of the device.
