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.

All-in-one liquid flow control system

Upgrade your existing pump system to be fully automated

Whether you are looking for an all-in-one solution or to upgrade your existing liquid pump system to full automation, CODA pump devices feature easy installation and accuracy up to ±0.2% of reading.

KG–Series Liquid Flow Pump Systems utilize a gear pump to create and control flow in an otherwise unpressurized system, while maintaining a setpoint measured through a CODA coriolis meter. This fully integrated system avoids the hassle of sourcing a pump and meter and developing a control system.
