Overview
The Omega FP-5300 flow sensor is an electro-mechanical paddlewheel transducer designed for accurate volumetric flow measurement in industrial and commercial systems. This sensor generates a sine-wave output with a frequency and amplitude linearly proportional to flow rate, making it ideal for process control, monitoring, and data logging applications. The FP-5300 handles flow ranges up to 20 feet per second and operates reliably across a broad temperature range.
Key Features
- Flow rate range 0.3 to 6 m/s (1 to 20 ft/s) with ±1% linearity and ±0.5% repeatability
- Accuracy of ±1% full scale with 1 V peak-to-peak output signal at 6 Hz per fps nominal frequency
- Open-cell rotor design eliminates cavitation at flow rates up to 50 FPS, maintaining superior linearity
- Designed for operation in 1/2 inch through 4 inch pipes with fully developed flow
- Sinusoidal AC voltage output proportional to flow velocity
- Flexible mounting options: horizontal pipes in upright position for best performance, or at maximum 45° when air bubbles present; vertical pipes require upward flow only
