Mass flow controllers
Flow meters and controllers from Alicat
Hositrad represents Alicat Scientific, a manufacturer of flow meters and controllers. We source the devices through Hositrad.
Alicat does not measure thermally but via the pressure drop across a laminar flow element. A single device therefore shows mass and volumetric flow, pressure and temperature at the same time and can be installed in any orientation.
Response time
from 4 ms
Measuring range
0.5 sccm to 500 slpm
Measured variables
4 in one device
Mounting orientation
any
Features
- Mass flow meters and controllers for gases
- Whisper series with very low pressure drop (from 0.2 psid, around 14 mbar)
- Flow meters and controllers for liquids
- Pressure controllers, also for vacuum control, and IVC integrated vacuum controller
- measures mass flow, volumetric flow, pressure and temperature
- can be installed in any orientation without recalibration
- with traceable calibration certificate (NIST)

Which version is right?
The flange, material, pressure range and process determine the version. We clarify this with you and Hositrad and also source custom-made parts to drawing.
