Mass Flow Controllers & Meters


L-Series: Liquid Flow Meters

Alicat L-series liquid flow meters simultaneously measure volumetric flow rate, liquid pressure, and liquid temperature in real time. Add an optional totalizer to track cumulative flow over time.

  • Fast, accurate, multivariate data. Immediately upon powering up, the meter is ready to display instantaneous volumetric flow rate, liquid pressure, and liquid temperature readings with NIST-traceable accuracy of 2% of full scale – 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 device ranges for L-Series

Alicat offers liquid meters with custom flow ranges from 0.5 CCM full scale to 10 LPM full scale, each with a measurement range of 2% to 100% of full scale. Custom devices are ranged to best meet your specific application needs for full scale flow rate and operating range.

It is important to note that some device specifications vary depending on the full scale flow rate.

Liquid flow characterization

Characterize the flow rate of water through a pump, or of saline fluid through medical tubing. The optional flow totalizer makes it easy to quantify the total volume of liquid that has flowed during the test.
