Low Flow Rate Flow Meters

Designed For Extreme Low Flow Rate Applications

The low flow meters are designed to measure flow ranges from .007 to 3gpm. Ideal for critical process measurement including ratio-metric batching in pharmaceutical or fuel blending. The LF series is available in a variety of process connections including flared, NPT, FNPT, and tube fitting. Manufactured to withstand pressures up to 20,000 psi and temperatures from -450 to 500°F, the LF Series is an ideal meter for your low flow applications.

Low Flow Frequently Asked Questions

Low flow rate meters are specialized flow meters designed to accurately measure very low flow rates, typically for applications where flow volumes are minimal.

Low flow rate meters are commonly used in industries requiring precise flow measurements at small scales, such as pharmaceuticals, chemical dosing, water treatment, laboratory research, and fuel or gas measurements.

Low flow meters can typically measure most liquids; however, the fluid’s viscosity, density, and particle content should match the specifications of the meter to maintain measurement accuracy and avoid wear.

Choosing the right low flow meter involves considering fluid type, flow rate range, required accuracy, pressure and temperature limits, and compatibility with your application’s environment.

Low flow turbine meters have excellent repeatability (the LF Series offers +/- 0.25% repeatability). This can be combined with a signal conditioner to offer linearity.
