Parker Conflow’s Code 477 is an in-line flowmeter that provides both flow and pressure measurement functions in one compact unit, allowing a diagnostic check on ITP systems on coal cutting machines.

The product combines the Parker Conflow Code 452 flowmeter, together with a pressure gauge block built in-line on the outlet. The pressure gauge block encompasses the features of the Code 91 Mine Gauge with the addition of an isolating valve built-in to the block. This isolates the pressure gauge from the system so that the gauge tube is only subject to the system pressure when a reading needs to be taken. The isolating valve is also used to restrict the hydraulic pulsation in certain circumstances so that a steady pointer indication ensues.

Code 477 is available in sizes from 3/4" up to 1 1/2" and to a maximum working pressure of 315 bar (1" unit).

Markets:
• Quarrying
• Mining

Features/Benefits:
• Extremely accurate as individually calibrated to -/±2% of indicated reading.
• Based on the reliable, robust 452 Flowmeter
• Glycerine filled for steady reading.

Applications:
• On board monitoring of ITP systems on coal cutting machines as a diagnostic check to ensure pressure and flow of water circuit is above the required trip levels.
