LORRIC's Patented Paddlewheel Flowmeter-AxleSense-

LORRIC's Patented Paddlewheel Flowmeter-AxleSense-

Introducing LORRIC AxleSense, a groundbreaking advancement in flow measurement technology. By incorporating our patented AxleSense innovation, we have transformed the traditional Hall effect, revolutionizing the way flow is measured. Our cutting-edge design strategically places induction magnets on the side of the axle, creating a continuous magnetic field that detects even the slightest rotation. This remarkable enhancement significantly boosts accuracy and empowers precise measurement of low flow rate fluids.

Traditional Paddlewheel Flowmeter- Hall effect -

Traditional Paddlewheel Flowmeter- Hall effect -

Traditional paddle wheel flowmeter commonly utilizes Hall effect measurement for flow monitoring. However, it has inherent limitations, particularly when it comes to accuracy and measuring low flow rates. These limitations arise primarily from the 90-degree spacing between the blades.

LORRIC AxleSense technology produces 120 signals per revolution.

LORRIC AxleSense technology produces 120 signals per revolution.

A revolutionary advancement in flow measurement. By strategically placing magnets on the side of the axle, our innovative solution generates a signal every 3° and produces 120 signals per revolution.

Traditional paddlewheel flowmeter only produces 4 signals per revolution.

Traditional paddlewheel flowmeter only produces 4 signals per revolution.

Since traditional paddle wheel flow meter utilizes this Hall effect which has the magnetic sensors placed on each blade for measurement. This design only generates a signal every 90° and only produces 4 signals per revolution.

Wider Detection Range

Premium-grade pipe fitting: Built to last and leak-free perfection

Experience the pinnacle of durability with LORRIC's precision-turned pipe fittings. Crafted from extruded rod material, these fittings offer unwavering size consistency and a flawless, wave-free inner surface. The result? Reduced disturbances and higher measurement precision. With superior strength compared to injection-molded alternatives, our machined plastic pipe fittings eliminate concerns like flash, short shots, and weld lines. Say goodbye to compromises and embrace the reliability and quality you deserve.

Traditional plastic injection molding methods often result in uneven surfaces and wave-like patterns on the inner walls of tee fittings. This is because the melted plastic is compressed, causing greater shrinkage in thicker areas. As a consequence, the pipe's cross-sectional area becomes inconsistent, leading to unstable fluid flow and inaccurate calculations. Additionally, injection-molded fittings are prone to issues like flash, short shots, and weak weld lines, making them more susceptible to damage over time. In contrast, LORRIC's tee fittings are manufactured using a different approach, ensuring smooth and reliable performance while overcoming the limitations of conventional techniques.

Dual LCD/LED screens for easy traffic and equipment status monitoring

  • High-brightness large LED screen for easy long-distance flow number reading.
  • LCD screen backlight with three-color warning light signal for visual monitoring of flow meter's normal and abnormal conditions.

* The device is calibrated with water at normal temperature before leaving the factory. Using fluids with viscosities different from water may result in inaccurate calibration values and could affect the minimum and maximum flow rates.
** The working temperature range for each material is provided as a reference. Please use your design experience to make the final material selection.
*** The measurement accuracy is determined through laboratory testing with clean water at a controlled room temperature of 25 degrees Celsius. Actual usage conditions may introduce errors.
**** IP66 stands for 'Ingress Protection,' which signifies the degree of protection an electrical device's enclosure offers against foreign object intrusion. The IP rating format consists of two digits, expressed as IPXX. The first digit denotes the level of protection against solid objects, particularly dust resistance, while the second digit indicates the waterproof protection level. A higher number signifies better protection. In the case of IP66, the first '6' indicates full dust protection, while the second '6' means no harm from high-pressure water splashes.
