The ICON Truflo UltraFlo 4000 series ultrasonic flow meter uses ultrasonic technology to measure both conductive and non-conductive liquids, and is an excellent choice for very corrosive liquids such as strong acids and alkalis. UltraFlo has no moving parts and can measure pulsating, dosing, and metering flow applications. All parts that contact liquid are made of corrosion-resistant Polysulfone. The UltraFlo 4000 is characterized by its high measurement accuracy and its heavy-duty design.

Available in 1/2, 3/4, 1, and 1-1/4 inch sizes, with measuring ranges from 0.3-21 LPM up to 5.0-240 LPM (0.08-63 GPM). Outputs include RS-485, 4-20mA, and pulse relay. The IP67 enclosure ensures protection in harsh environments. PVC-CPVC true union ends are optional.
