Flow sensor Panasonic BE-A301P, operating voltage 5–24 V DC, dimensions 20×15.5×16.5 mm

Panasonic BE-A301P is a compact flow sensor for inline fluid monitoring that operates on a low-voltage DC supply. With an operating voltage range of 5–24 V DC and conservative external dimensions of 20 × 15.5 × 16.5 mm, this sensor is designed for integration into space-constrained systems and OEM assemblies. It detects liquid flow and provides a straightforward means to monitor movement of fluids in control panels, laboratory instruments, or automated machinery.

Advantages

The sensor combines a wide low-voltage operating range with a very small physical footprint, enabling installation in tight spaces without additional power-conversion hardware. Its compact size reduces the need for panel real estate and supports easy integration into existing fluid lines. The design supports reliable flow detection in small-scale applications where stable low-voltage operation is required.

Suitable for

• Inline monitoring of liquid flow in control panels and small fluid circuits
• Laboratory equipment and benchtop instruments with limited space
• OEM assemblies and compact automated machinery
• Low-voltage applications and battery-powered systems

Key specifications

• Operating voltage: 5–24 V DC
• External dimensions: 20 × 15.5 × 16.5 mm
• Function: liquid flow detection (inline)
• Mounting: designed for integration into small fluid lines and assemblies

How to use

Install the sensor inline with the fluid path ensuring correct flow direction and secure connections to prevent leaks. Connect the device to a compatible 5–24 V DC supply and interface its signal output to the monitoring or control system according to the system’s input requirements. Verify electrical connections and perform a functional check with fluid flow at expected operating conditions to confirm detection and signal reliability.

Recommendations

For consistent performance, mount the sensor where flow is steady and free from air pockets, and avoid locations subject to excessive vibration or temperature extremes. Follow system-level wiring and protection practices, including appropriate fusing or current limiting for the chosen supply voltage. If integrating into sensitive instrumentation, validate signal compatibility and, if necessary, use buffering or filtering to match downstream electronics.
