पैडल व्हील फ्लोमीटर कैसे काम करता है?
Paddle wheel flow meter measure flow by using fluid to drive the rotation of blades, with the rotational speed proportional to the flow rate. Suitable for measuring low-viscosity liquids like water, oil, and chemicals, these meters are characterized by moderate accuracy, quick response, and easy installation and maintenance. Due to direct contact with the liquid, regular cleaning and inspection are required.
Wider Detection Range
Traditional paddle wheel flow meter often have significant errors or cannot detect flow at low flow rates in the fluid inside the pipe. Upgrade your flow measurement capabilities with LORRIC's AxleSense technology! No more worries about inaccurate readings or missed low flow rates. Our advanced innovation ensures enhanced accuracy and a broader measurement range, spanning from 0.15 m/s to 10 m/s—double that of competing brands.
Bi-Directional Flow Detection
AxleSense's patented technology enables bidirectional flow detection by measuring paddlewheel rotation direction, overcoming the limitations of other brands that use Hall effect sensors, which can detect rotation but not direction. This technology also provides fluid flow direction information, positive/negative/net flow calculations, and a 14-day history of daily accumulations, optimizing operations and enhancing on-site management efficiency.
Real-Time Smart Detection
Provides clear paddle anomaly alerts, essential for Industry 4.0 integration. It quickly resolves flow issues by syncing with factory management systems. Built-in magnetic sensing checks paddlewheel magnet strength, ensuring consistent flow accuracy through regular monitoring and scheduled replacements.
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.
Screen can be switched according to vertical or horizontal piping
Adjust the viewing direction of the screen according to the piping direction, which is convenient for flow monitoring in different piping situations.

Multiple Communication Outputs
FU-ES supports various communication modes like Analog output with self-powered 16-bit 4-20mA, Modbus RTU RS485, 2-wire photoelectric switch signal (compatible with NPN/PNP). No need for additional communication modules – we've got you covered!

Pulse 2.0 Technology
Traditional pulse output paddle wheel flow meter use a constant K-value across the entire range, leading to higher errors, especially at varying flow rates. For instance, a conventional paddle wheel flow meter in a DN15 pipe outputs one signal every 90 degrees, with 106.55 pulses equaling 1L, regardless of flow speed.
LORRIC’s exclusive Pulse 2.0, powered by AxleSense technology, outputs one pulse per 0.01L, reducing errors by adjusting for different flow speeds.

* 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.
