The new Platon Fire Sprinkler flow-meter Model LPCB, from Roxspur Measurement and Control, was developed to meet the requirement for a direct reading flow-meter for use in automatic sprinkler installations, water spray or deluge systems. The Model LPCB provides a direct reading flow-meter for 50mm-200mm pipelines, and is suitable for installation in horizontal or vertical pipes. The Model LPCB is installed between flanges or Victaulic connections on the main water delivery line. The measurement principle is based on an orifice plate in the main flow line, which produces a pressure drop dependent on flow rate. Model LPCB features full bore isolating valves to close the bypass flow line, allowing meter isolation for filter cleaning or flow tube replacement. A key feature of the design is the housing with its polycarbonate window, which protects the flow-meter glass tube on site. All the flow tubes have a 100mm long fused-in ceramic scale, calibrated at the various test flows specified by LPCB. The test flows used range from 500 to 9000 dm3/minute.
