Flow & Pressure Meters Code 477G

The Conflow Code 477 – Flow and Pressure Meter indicates the volume rate of flow and the system pressure in a fluid pipeline. The product is the Code 452 Flowmeter together with a pressure gauge block built in line on the outlet.

This concept overcomes the normal problem of fitting a standard pressure gauge in a vulnerable position on the side of a flowmeter. 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.

Typical 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

Features

  • Sizes from 3/4" up to 1 1/2"
  • Maximum working pressure 315 bar (1" unit)
  • Individually calibrated to ±2% of indicated reading
  • Provides the ability to monitor Flow and Pressure within the water circuit
  • Based on the reliable 452 Flowmeter
  • Glycerine filled for steady reading
