Turbine Flow Meter
ONICON INC | Part Number: F1211
Insertion turbine flow meters are suitable for measuring electrically conductive water-based liquids. Provides isolated 4-20 mA and 0-10 V isolated analog output signals that are linear with the flow rate.
Ships in 4-6 weeks
Patented electronic sensing is resistant to scale and particulate matter. Custom calibrated, highly accurate instrumentation at very competitive prices. Allows for insertion and removal by hand without system shutdown.
