The Oval PD-UA-4 Flow Meter (LC293-UAO-C115-412) is a high-precision, industrial-grade flow measurement instrument designed by Oval Corporation Japan, a globally recognized leader in flow technology. Developed for demanding industrial and marine environments, this Ultra Oval positive displacement flow meter offers superior accuracy, repeatability, and long-term reliability for liquid flow applications.
Featuring a maximum operating pressure of 14 kgf/cm² and a wide temperature tolerance ranging from -10°C to 60°C (fluid temperature up to 120°C), the PD-UA-4 is ideally suited for LDO (Light Diesel Oil) measurement, fuel management, lubrication systems, and high-precision fluid flow monitoring. Its robust construction ensures stable performance under varying flow conditions.
The meter supports internal flow rates between 6–90 m³/h, continuous flow between 6–70 m³/h, and a full-scale range of 0–70 m³/h. The integrated pulse output with a resolution of 0.001 m³/p enables real-time monitoring and integration with PLC, SCADA, automation systems, and fuel consumption management platforms.
Built with explosion-proof certification Exd II BT4 / Exia II BT4, this flow meter is suitable for hazardous industrial zones, petrochemical plants, marine engine rooms, offshore rigs, and fuel storage systems. Powered by 45 VDC with low current consumption, it ensures efficient and safe long-term operation.
