Alicat L Series Liquid Flow Meter

  • Fast, accurate and repeatable volumetric flow measurement
  • 20-ms speed of response
  • Full scale flow rates from 0.5 CCM up to 10 LPM
  • ±2% of full scale accuracy
  • No warm-up time required

Alicat L Series liquid flow meters use patented laminar flow design to provide a fast, accurate and repeatable volumetric flow measurement. Every device allows simultaneous display of the volumetric flow rate and line temperature, there is an option to add line pressure also.

Like all Alicat devices there is no warmup time so the meter is ready to go in one second.

Full scale flow rates are from as little as 0.5 CCM up to 10 Litres per minute with a meter turn down ratio of 50:1. Alternate calibrations are available for methanol, iso-propanol, ethanol, ammonia, dimethylether, iso-pentane, thiophene, iso-octane and heptane.

Devices are available with a 0-5, 1-10, 0-10 Vdc or 4-20 mA analog outputs. RS 232 comms are standard with other options also available.

Easy to access front bleed ports for easy removal of trapped air.

CSA/ATEX area classification is optional. Ex nA IIC, T4 Tamb. -40°C ≤ Ta ≤ +50°C
