Parker Conflow’s Code 452 is a highly accurate flow meter that indicates the volume rate of fluid flow in a pipeline or hydraulic system in mining or quarrying applications and is suitable for systems with varying flow and/or extreme oscillation.

With Code 452, readings are accurate throughout the full scale to +/-2% due to factory setting and hand marking of the scale. The flow meter is also glycerine-filled to protect from any bouncing of the needle, enabling reliable readings to be taken.

Code 452 enables flow to be set to specific rates, with a wide range of rates available to suit customer requirements.
Filtration must occur before the meter to prevent inaccurate readings or no response due to a blockage.

Code 452 is available in 1/2" to 3" sizes and operates to a maximum working pressure of 315 bar (1" unit).

Markets:
• Quarrying
• Mining

Features/Benefits:
• Individually calibrated to ±2% of indicated reading.
• Heavy duty construction.
• Glycerine filled to damp needle pulsations and prevent misting of viewing window.
• Units equipped with side ports, for pressure gauge fitting.
• Rugged and compact unit.
• Has a side connection so it can fit a pressure gauge.
• Hand marked to ensure accuracy.
• Readings in single or dual scales, litres or gallons per minute.

Applications:
• Monitoring water or oil flows to the various systems on coal cutting machines, AFC gearboxes and roof bolting machinery.
• Monitoring water lines for dust suppression, motor cooling, ITP systems and fire fighting.
