FAQ

Which flow meter is best for extremely low water flow rates?

It depends on the flow range and media conductivity. For sub-10mL/min (10 ccm) ranges, an oval gear flow meter is the standard choice. or if you flow down to 1 ml/min, you can consider our micro Coriolis flow meter. For conductive water, a low flow magnetic flow meter works well. For non-conductive or ultrapure water, use a micro turbine or micro Coriolis flow meter instead.

Can a low flow magnetic flow meter measure pure or deionized water?

No. Magnetic flow meters rely on the conductivity of the media. Pure water and deionized water have conductivity too low for accurate measurement. Use a micro turbine or micro Coriolis flow meter for these applications.

Which is more accurate for low water flow, a rotameter or a turbine flow meter?

Turbine flow meters are generally more accurate and can output a pulse signal for automation and control. Rotameters are simpler and lower cost, typically used for local visual indication, but offer lower accuracy and slower response.

Does accuracy suffer at such low flow rates with a Coriolis meter?

No. Coriolis meters measure mass flow directly and are not affected by density, viscosity, or conductivity. Even at flow rates as low as 40 g/h, accuracy remains stable, which is why Coriolis meters are common in lab and ultrapure water applications.

Do these low flow water meters need regular calibration?
