The Alicat Scientific L Series liquid flow meter measures differential pressure within a laminar flow region to determine volumetric flow rate. This proven method of flow measurement allows the L series to achieve substantial turndown, accuracy, and linearity across a wide flow range making it a cost effective solution for a number of liquid flow applications. A flow controller version of this meter, The LC Series, is also available.

The Alicat Scientific L Series differential pressure flow meter features a flow range from 0.5 cubic centimeters to 10 liters per minute full-scale, with standard turndowns of 50:1. The meter has a basic accuracy of ±2% FS and is repeatable to ±0.5% FS. The a digital display shows process conditions like liquid temperature and liquid pressure in addition to liquid flow rate. The L series liquid flow meter can act as three measurement devices which simplifies any process. A variety of connection, alarm and output options are available making this a truly versatile instrument.

The Alicat Scientific LC Series liquid flow controller utilizes a proportional valve coupled to a flow meter body creating a unique closed-loop flow controller system for ranges from 5 to 500 cubic centimeters/minute. The integral PID controller positions the valve according to the flow set points. These devices accept a selectable analog or digital control signal from either external devices or locally. Multiple input and output options are available. The LC Series has a dynamic digital display that simultaneously shows all the measured parameters within the meter plus a push button operator interface allows the user to select a specific parameter for the main display, make set point and control adjustments or tare the meter.

Alicat Scientific L Series flow meters and LC Series flow controllers are small enough to fit in your hand and, when combined with the battery pack accessory, are completely portable making them true stand-alone measurement devices that can be used in remote systems where power is not available or as calibration devices for embedded meters in the field. The L and LC series come ready to install from the factory.
