Laboratories, industrial plants, process facilities and field technicians have all gained substantial advantages from Alicat portable flow meters.

Instead of spending your time finding (or hard wiring) a power source, you can utilize our portable meter with gas selection and multiple parameter measurement features to:

• Verify proper operation of equipment, including other manufacturer’s mass flow meters and mass flow controllers.
• Maintain proper equipment settings as components within the system wear down.
• Search for leaks in the system utilizing the pressure reading or the flow reading.
• Install equipment and perform initial tuning and adjustments in the field.
• Perform periodic system checks for quality control and verification.

A common 9Vdc battery powers one of Alicat's M Series mass flow meters for 8 - 10 hours! A low battery warning indicator alerts users to replace the battery. (MB units only)
This affordable device displays mass flow & volumetric flow along with process temperature and pressure for 30 field selectable gases.
The unit can also be powered with an optional AC/DC plug-in adaptor.

Add Alicat's Industrial Carrying Case for a rugged, field ready flow verification device or transfer standard.


Many of our customization features are compatible with our Portable Meters, including:
