Ultrasonic Liquid Flowmeters 
Model SLF-500
   -The Model SLF-500 Ultrasonic Liquid Flowmeter is an accurate, reliable and 
    cost-effective clamp-on ultrasonic instrument capable of measuring bidirectional 
    flow through metal, plastic and   even lined pipes without altering the piping.
   -Typical applications include corrosive chemicals in the process industry, 
    DI water and chemicals in the semiconductor market, fluids in the sanitary industry, 
    or any installation where it is preferable not to have an instrument exposed to the 
    process fluid.
