Truflo® Multi-Function UltraFlo 4000 Flow Meter

UltraFlo 4000 Flow Meter

Continuous + Dosing + Pulsating Flow

All Plastic Ultrasonic Measurement Technology – Plug & Play

UltraFlo 4000 is a Flow Meter calculating the volume Flow of Liquids. Based on ultrasonic technology the UltraFlo 4000 is able to measure both conductive and non conductive liquids, as well as very corrosive liquids such as strong acids and alkalis. UIltra Truflo® has no moving parts and is absolutely free of wear. The design of the pipe minimizes dead space over the whole geometry. All parts having contact to the liquid is corrosion resistant Polysufon. UltraFlo is characterised by its high measurement accuracy and repeatability.
