Portable Flow Meters

Alicat's new rechargeable portable mass flow meter

Alicat’s rechargeable portable mass flow meter

A full featured mass flow meter that fits in your pocket

A rechargeable battery-powered instrument, Alicat’s MB series mass flow meter is the perfect instrument for verifying flow rates in places that are off the beaten path. With 18 hours of continuous operation on a single charge and +/-0.8% of reading accuracy, these handheld meters bring laboratory-class accuracy to field flow verification and validation applications in the environmental, manufacturing and metrology industries.

Due to the low power consumption inherent to Alicat’s M series mass flow meter Alicat has created the MB series portable mass flow meter. Drawing from a rechargeable battery as a power source the Alicat MB series mass flow meter is routinely used a portable transfer standard or hand carry flow meter. The MB series meter is also equipped with a connectors for hard power and for analog and digital output, allowing it to be used as in fixed installations while relying on its rechargeable battery as a backup power source should hard power be lost.


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.

Full featured

    • A rechargeable battery powers one of Alicat’s M Series mass flow meters for 18 hours! A battery life remaining indicator alerts users to charge the battery. (MB units only)
    • The MB series device displays mass flow & volumetric flow along with process temperature and pressure for 30 field selectable gases allowing the device to be used in a variety of applications and under a variety of conditions.
    • The MB series device can also be powered with an 5V micro USB adapter allowing it to be used a backup device of to be hardwired into the a process relying on the battery as backup power.
    • Battery power remaining indicator
    • Auto switch between battery and hard power when hard power is present.
    • 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:
