Description Vendor

ACE DPFM/DPFC500 is the larger high-flow differential-pressure mass-flow controller series for gases including hydrogen. The current ACE page lists a 1,000–5,000 SLM target range and 1,000, 2,000 and 3,000 SLM full-scale configurations, while explicitly limiting hydrogen service to a maximum of 1,000 SLM. The design uses minute differential-pressure measurement to reduce pressure loss and maintain compact high-flow plumbing. ACE specifies ±3% FS accuracy, ±0.5% FS repeatability and a typical response within two seconds for the listed configurations.

Use Cases

  • High-flow hydrogen test systems
  • Fuel-cell gas supply infrastructure
  • Industrial hydrogen flow control where low pressure loss is required

Capabilities

  • Measures and regulates high gas flows using minute differential pressure
  • Maintains low pressure loss at high flow
  • Supports hydrogen operation up to the stated hydrogen limit
  • Provides fast closed-loop flow response
ACE Inc. Our company was established and founded in March 1999 as ACE Co., Ltd. It began business with the primary business of developing components and providing application equipment based on fluid measurement, control, and monitoring technologies. Since then, through the development of gas analysis equipment, gas mixing equipment, surface treatment technologies, and more, our products and systems are active in a variety of fields, including semiconductors and liquid crystal displays, fuel cells, environmental analysis, and general industrial fields. With our motto of "Creation and Challenge," we will continue to make further efforts and improve our technology in order to meet our customers' expectations.
