Summary for turbine flowmeter Discussion
Flow meters for a plating line were discussed in the context of measuring mains-water and DI-water usage so the shop could compare water input and output against wastewater treatment capacity. Ryan McGrory asked for recommendations for low-conductivity liquids, noting that many ultrasonic meters require at least 100 ppm and are not suited to very clean water such as 2 µS/cm DI water. In reply, Leon Gusak suggested looking at a turbine flowmeter, explaining that a small turbine inside the meter rotates in proportion to flow rate. He added that because the application is water rather than corrosive chemicals, there should be a wide range of suitable meter options. The thread does not report a final selection or field test, but it points to turbine meters as a practical place to start for this low-µS/cm plating-line application.
Q. Hi all,
Looking for some information for flow meters that can be used in plating line. The reason for this is to measure our water input & water output so we can check with our waste water treatment plant capacity.
Our plating line uses Mains water for rinsing tanks and DI water (2µS/cm) for process tanks, Would anyone have any recommendations for flow meters that they have used that would work successfully at low µS/cm? Most I’ve been looking at, i.e., ultrasonic, need a minimum of 100 ppm … not for clean liquids.
Is there anyone who has experience of using them on a plating line with DI tanks?
Any help would be appreciated.

A. Hi Ryan
Probably you can try to search for “turbine flowmeter”. They may work in your situation. Small turbine inside the flowmeter rotates proportionally to the liquid flow rate. As you plan to use it for water (not corrosive chemicals) it should be a very wide selection of different flowmeter options.
