EPR Series Paddle Wheel Flow Meter

Introduction – EPR Series Paddle Wheel Flow Meter

The EPR Series Paddle Wheel Flow Meter is designed to measure liquid flow using a rotating blade mechanism that accurately captures velocity changes within the medium. Its paddle structure is engineered to operate reliably across a linear velocity range of 0–10 m/s, ensuring responsive flow measurement without causing hydraulic shock or reducing flow speed. The compact and miniaturized construction supports efficient installation while maintaining high measurement integrity.

To achieve precise results, the EPR Series eliminates common mechanical error sources such as bearing friction, axial friction coefficient variations, and blade resistance effects. Each unit undergoes real flow testing, enabling accurate K-factor calibration based on actual measurement conditions. The system is suitable for applications requiring consistent and dependable flow monitoring in industrial processes, including those served by Dubai Sensor in the UAE and wider MENA region.

Equipped with a separate display unit and a reliable sensing body, the instrument supports clear data visibility and stable operation. The device integrates advanced electronics, including a 128×64 LCM display, 4–20 mA analog output, MOSFET SSR switching output, and RS485 Modbus communication. With wide voltage tolerance and FRAM-based cumulative flow storage, the EPR Series offers durability and long-term operational confidence across diverse flow measurement environments.
