MEMS-Thermal Mass Flow Meters & Controllers

Small flow instruments with premier performance

Alicat Scientific’s smallest BASIS 2 mass flow instrument line uses MEMS thermal technology to measure mass flow.

Cost-effective, small enough to fit in the palm of your hand and yet packed with impressive performance. Work with our engineering team for custom manifolds and gas mixing arrays.

  • Accurate flow control in a compact, durable, metal flow body.
  • Run sophisticated flow-control scripts using a fast, robust Alicat ASCII command set.
  • Dispense dosing and batches with a built-in totalizer.

Quickly establish fast control

Control device optimization can provide the best device response for a particular process and environment. Automated optimization, such as Alicat’s Autotune function, makes it possible to measure current performance and improve it, without requiring extensive knowledge of control systems and parameters.

Learn how to optimize your control response with Autotune with this whitepaper on response time optimization.
