Liquid Mixing & Delivery

Standard Features

  • Mix and Match modules to deliver various flow rates and liquids. Gas delivery modules are also available
  • Flow rates are controlled by liquid mass flow controllers, peristaltic metering, positive displacement diaphragm, or piston metering pumps
  • Ethernet Interface for simple configuration and expansion!
  • The output from multiple Liquid Delivery Modules may be combined to provide dynamically controlled gas flow rates and compositions, including Stoichiometric control
  • 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, inlet liquid pressure, liquid enabled, and power
  • Pressure regulator on inlet liquid lines to provide the highest degree of accuracy, and check valves for liquid backflow prevention

Typical Applications

  • Fuel Cell Testing
  • Liquid Blending
  • Sensor Testing
  • Environmental Chambers
  • Catalyst Testing and Evaluation

Modules Available

  • Liquid Delivery- offers flow control of one liquid
  • Dual Liquid Delivery- separate inlets, liquid flow controllers, and outlets of two distinct liquids
  • Liquid Blending Module- two independent flow controlled liquid streams are mixed before exiting the module
  • Extended Range Module- contains both a high flow and a low flow liquid flow controller which allows for a turndown ratio of up to 1000 to 1 in a single module

Optional Features

  • Also available as dual channel, liquid blending, and extended range
  • Upgrade to ultra high purity materials and surface finish
  • Manifolds and static mixers Hot Swap-Ability! When the system is running, it has the capability of swapping a redundant module (if so equipped) for the primary module
  • Pneumatic valve shutoff
