The Flocat LA10-A gas flow meter uses two of the best-studied physical properties of gases to measure flow: Pressure and Viscosity. Differential pressure measurement across a laminar flow element results in a gas flow meter that is inherently linear. Flocat LA10-A gas flow meters measure within the laminar region to achieve turndowns of 100:1 typically. A very wide range of measurement, 0.5 milliliter per minute full-scale to 1500 liters per minute full-scale, is standard. Unique laminar flow elements, along with modern electronics, ensure that each Flocat LA10-A gas flow meter is both affordable and accurate.

The Flocat LA10-A gas flow meter is a simple yet rugged device. The membrane switch user interface and dynamically labeled graphic display combine to provide exceedingly flexible and user-friendly operation. The Flocat LA10-A gas flow meter can have several screen "modes" depending on how the device is ordered.

Volumetric Flocat LA10-A gas flow meters are intended for use in low pressure applications. This is because an accurate measurement of the volumetric flow rate by means of differential pressure requires the flow at the differential pressure sensor to be in a laminar state.

The Flocat LA10-A is also available with flow control capability.
