## Long description

Barrow WABW-255 OLED Black is an inline flow meter for liquid systems with an integrated OLED display that shows real‑time flow rate. The device installs directly into piping to measure liquid throughput and provides on‑device numerical readout and status information. Its compact, black housing and clear OLED panel make it suitable for visible monitoring in confined or exposed installations without requiring external display hardware.
Advantages
The flow meter delivers continuous flow measurement with an on‑unit OLED display for immediate visual feedback. Its inline design enables direct integration into closed liquid loops, reducing the need for remote sensors or long signal cables. The compact footprint and black finish allow discreet mounting in water‑cooling systems, laboratory rigs or process lines. The unit is designed for straightforward installation and maintenance, offering dependable readings for routine monitoring.
Suitable for
PC water‑cooling loops where visible flow monitoring is required
Laboratory or test-bench liquid circulation setups
Small industrial process lines and pilot systems
Applications needing compact, on‑device flow readout without separate displays
Key specifications
Inline liquid flow measurement with integrated OLED display
Compact black housing suitable for exposed or confined mounting
Real‑time numeric flow rate readout on device
Designed for installation into liquid piping and closed loops
Suitable for water‑based coolants and common laboratory liquids (verify compatibility with specific fluids)
How to use
Install the flow meter in the liquid circuit following the flow direction marked on the unit. Ensure compatible tubing or fittings are used to achieve a leak‑free connection and that the sensor is mounted in a location allowing clear visibility of the OLED display. Power and any required signal connections should be made according to system requirements; confirm electrical connections and sealing before filling the circuit. After installation, prime the loop and observe the OLED to verify stable flow readings. Periodic inspection of fittings and a visual check of the display are recommended to maintain reliable operation.
Usage recommendations
Use the Barrow WABW-255 in systems with clean, filtered liquids to reduce sediment buildup. Avoid aggressive chemicals or fluids not recommended for general-purpose flow sensors. Position the meter after a pump stabilizer or in a straight section of pipe to minimize turbulence for more accurate readings. Regularly check sealing points and clean the display area to ensure clear visibility of measurements.
