Who is Alicat Scientific?

Alicat Scientific

Made in the USA since 1991 More than 100,000 Alicat mass flow and pressure instruments are in operation around the world. They help monitor the air you breathe, prepare the food you eat, build the products you buy and make the world a safer place. Alicat’s product lines include mass flow meters and mass flow controllers, pressure controllers and digital pressure gauges for gases and liquids.

Our Relationship with Alicat Scientific

Action Instruments has been the sole importer to South Africa for Alicat Scientific’s instrumentation for over 10 years.

What does Alicat Scientific Do?

They make the world’s fastest mass flow meters, mass flow controllers and pressure controllers.

Mass Flow Meters and Controllers

Stable, responsive control of process flow rates and pressures with real-time readings of mass flow, volumetric flow, temperature and pressure. Portable flow calibrators provide instant verification of flow rates.

  • Available ranges: max 0–5000 SLPM; min 0–0.5 SCCM
  • Steady-state control range: 0.01% – 100% of full scale
  • Standard accuracy calibration, NIST-traceable: ±0.6% of reading or ±0.1% of the full scale
  • Optional high-accuracy calibration, NIST-traceable: ±0.5% of reading or ±0.1% of full scale
  • Repeatability: ±(0.1% of reading + 0.02% of full scale)
  • Typical control response time: as fast as 30 ms
  • Warm-up time: <1 s

Liquid Flow Meters and Controllers

Monitor and control liquid flows with industry-leading response times that can keep up with even the fastest of dosing and dispensing applications. Available with simultaneous line pressure readings.

Laminar Liquid flow meter

Simultaneously measure volumetric flow rate, liquid pressure, and liquid temperature in real-time.

  • Fast, multivariate data. Millisecond-response times immediately upon powering up, to display liquid flow, pressure, and temperature readings in real-time, in your choice of engineering units.
  • Easy integration. Custom process ports and electrical connectors in addition to your choice of EtherNet/IP, EtherCAT, DeviceNet, Profibus, Modbus (RTU and TCP/IP), or serial communications options enables easy integration into your industrial process.Available ranges: max 0–10 LPM, min 0–0.5 CCM
  • Flow measurement range: 2% – 100% of full scale
  • Calibration accuracy, NIST-traceable: ±2% of full scale
  • Repeatability: ±2% of full scale
  • Typical measurement response time: <10 ms
  • Warm-up time: <1 s

Coriolis Liquid and Gas Flowmeters

High accuracy measurement under extreme operating conditions. CODA meters are compatible with a wide range of liquids and gases (including many corrosives), and maintain high accuracy for pressures up to 4000 PSIA and flow rates down to 40 g/h.

  • Versatile measurement. Measure mass flow even when fluid composition is changing or unknown, with NIST-traceable accuracy to ±0.2% of reading and repeatability to ±0.05% of reading.
  • Robust material compatibility. Available with wetted materials that are compatible with a wide range of aggressive gases and liquids.
  • Insensitivity to external vibration. Inherent resistance to external vibrations mitigates environmental process disturbances.Available ranges: max 0–100 kg/h; min 0–40 g/h
  • Flow measurement range: 0.2% –100% of full scale
  • Accuracy calibration, NIST-traceable (liquid): ±0.2% of reading or ±0.05% of full scale, whichever is greater
  • Accuracy calibration, NIST-traceable (gas): ±0.5% of reading or ±0.05% of full scale, whichever is greater
  • Repeatability: ±0.05% of reading or ±0.025% of full scale, whichever is greater
  • Zero stability: ±0.05% of full scale
  • Typical measurement response time: <100m

Pressure Controllers and Gauges

Control the absolute, gauge or differential pressure of your flowing, dead-ended or vacuum applications in real-time. Dual-valve controllers eliminate the continuous outgassing of expensive process gases.

Pressure Controller Alicat with display front view.
  • Fast & accurate. Custom valve sizing and PID tuning ensure controllers reach pressure setpoints in milliseconds and maintain control with NIST-traceable accuracy to ±0.125% of full scale.
  • Versatile control. Maintain absolute pressure (referenced to vacuum) or gauge pressure (referenced to local barometric pressure) immediately upon powering up, with readings displayed in your choice of engineering units.
  • Easy integration. Custom process ports and electrical connectors, and your choice of EtherNet/IP, EtherCAT, DeviceNet, Profibus, Modbus (RTU and TCP/IP), or serial communications for easy integration into your industrial process
  • Available ranges:
    • Absolute: max 0–200 bar; min 0–1 bar
    • Gauge: max 0–200 bar; min 0–0.14 bar in H₂O*
    • Differential:  max –34 to +34 Bar; min –0.14 to +0.14 Bar in H₂O
  • Steady-state control range: 0.01% – 100% of full scale
  • Standard accuracy calibration, NIST-traceable: ±0.25% of full scale
  • Optional high-accuracy calibration, NIST-traceable: ±0.125% of full scale
  • Repeatability: 0.08% of full scale
  • Typical control response time: as fast as 50 ms
  • Warm-up time: <1 s

Action will help you find the right Alicat solution fast. All their instruments include NIST-traceable calibration and the industry’s only lifetime warranty. These are some of the reason why companies like NMISA, SABS, Sasol, Mintek etc has chosen these products over the years.
