  • Mass flow metering of the delivered test gas at flow rates up to 4000 SLPM
  • Electronic pressure controller allows the user to control the pressure of the leak rate gas being delivered to the internal mass flow meter
  • Control of isolation and delivery valves to evaluate different portions of the device under test
  • All-digital control eliminates analog calibration requirements and inaccuracies
  • Ethernet Interface for simple configuration and expansion!
  • System-wide control of all Fideris® Test System Components using FCPower Software, Labview, or other programming language
  • Integrated hardwired Run/Standby signal
  • Power Over Ethernet (PoE) for redundant power
  • Front panel LED status of Ethernet communications, test gas pressure, leak rate module enabled, and power
  • Pressure regulator on inlet gas line to provide the highest degree of accuracy and check valves for gas back flow prevention

Each module provides a turnkey solution for leak testing and measuring. The Leak Rate Module includes an electronic pressure controller, a bubble-tight inlet valve, a reverse flow protection check-valve, an upstream pressure regulator, and a pressure switch to provide status of the test gas inlet. Front panel display of flow rate and status provides for quick verification and easy diagnostics. The module comes in a standard rack mount size for simple integration into an existing fuel cell test stand or as part of a custom configured Fideris Fuel Cell Test Stand.
