Accurate and repeatable liquid flow measurement
Alicat’s L-series liquid flow meters uses our patented laminar flow design to provide users with fast, accurate, and repeatable volumetric flow measurement for water or selected other liquids (see Quick Specs below). At the heart of Alicat’s L-Series liquid flow meters is an internally compensated, laminar differential pressure measurement technology that yields linear results over a wide flow range.

L Liquid Flow Meters
- Alicat L-Series Part Numbers
- Alicat LB-Series Part Numbers
Monitor liquid flows down to 0.01 ccm with the fastest meter response time available in a liquid flow meter (20 ms).
Common Instrument Options
- In-line pressure sensor, provides simultaneous real-time readings of line pressure (up to 100 psig) in addition to flow and temperature readings.
- Flow totalizer, shows accumulated volumetric flow with display of elapsed time.
- 9-pin or 15-pin D-sub connectors, configured to match any existing pinout.
- Modbus-RTU, available over RS-232 or RS-485. PROFIBUS also available.
- Backlit color display, shines in low lighting environments.
