Parker FDHB500UK Series Flow Meter 2 to 20 L/min, 1-1/4 in, 1/4 in, 1/2 in, 3/4 in BSP FDHB500UK

Parker FDHB500UK Series Flow Meter is a robust and precise flow measurement instrument supporting flow rates from 2 L/min up to 20 L/min. Featuring selectable BSP connection thread sizes including 1-1/4 inch, 1/4 inch, 1/2 inch, and 3/4 inch, this flow meter adapts to diverse piping configurations in industrial settings.

This flow meter operates through an oil calibrated variable area mechanism where the flow passes through an annular orifice pushing a piston against a calibrated spring. The movement is indicated clearly with an indicator line against an indelibly printed colour-coded scale on a transparent tube, allowing direct and reliable flow rate readings without fogging or clouding.

Engineered to work reliably in any orientation, the FDHB500UK is suitable for horizontal or vertical installation, handling pressures up to 350 bar and operating temperatures up to 90°C. Its wetted materials include brass, fluoroelastomer, and stainless steel, selected for durability and corrosion resistance in various industrial and hydraulic applications.

The device boasts a flow accuracy within ±5% of full scale deflection (FSD) and repeatability of ±1% FSD, making it an excellent choice for process monitoring, hydraulic oil flow measurement, and other fluid handling systems requiring precise flow regulation.

This flow meter series conforms to British standards BS970/1:1991:316S31, BS 2056 EN 58J, and BS 2874 CZ114 ensuring compliance with recognized industry quality benchmarks. Its robust construction and proven design support reliable performance in automotive, manufacturing, water treatment, and laboratory environments.
