• Use in conjunction with batch or flow controller for precise pump control • PFA sensors meet requirements of US Pharmacopeia Class VI These liquid turbine flow sensors are corrosion resistant for long-term, trouble-free performance in demanding situations. Sensor is positioned in close proximity to the edges of the rotor blades to provide accurate flow measurements for all colored liquids. Flow in your tubing is picked up via the IR beam in the sensor connection, and converted into a 5 to 30 V square wave pulse output. One meter of PVC cable is included with an RVC jack for input into the batch or flow controllers (sold separately below). If using a recorder, panel meter, or PLC, simply remove the jack to expose the two-wire cable for installation of voltage output.Mount these turbine flow sensors in any position; they do not require a flow straightener or other specialized installation. The PFA and PVDF sensors are replaceable for single-use applications or can be set up as permanent flow sensors. PFA and PVDF sensors come standard with a mounting clip; polypropylene tube holders are also available (contact our Application Specialists). Sensors are available with hose barb or threaded fittings. PVDF Turbine Sensors<\/b> are available with hose barb connections for lab or process use. PVDF sensors are generally used in applications requiring high-purity flow sensing of solvents, acids, and bases.
