Flow meters for low flow applications

A leak-test engineer needs to catch 2 sccm of nitrogen bleeding past a valve seal, and the plant's standard inline meter shows nothing. That gap, rates too small for ordinary instruments to register but too important to ignore, is what this category of equipment is built to cover.

A low flow flowmeter (also called a small flow meter) is a specialized flow measurement instrument designed to accurately measure and monitor very low flow rates of fluids or gases, typically expressed in units such as SCCM (standard cubic centimeters per minute), ml/min (milliliters per minute), or g/h (grams per hour).

These instruments fall into two measurement types. Volume meters, such as positive displacement or turbine designs, count discrete volumes or rotor turns. Mass meters, such as Coriolis or thermal dispersion designs, measure the substance directly, with no pressure or temperature correction needed.

Silver Automation Instruments builds and stocks the following low flow models, with tested low-end ranges:

Application	Our meter	Low end of range
