لول ترانسمیتر اُلتراسونیک (Ultrasonic level theransmiter) یکی از پرکاربردترین تجهیزات در صنعت ابزار دقیق بوده و برای اندازه گیری سطوح غیر تماسی در مایعات، رب، مواد فله درشت و اندازه گیری جریان در کانال های باز و یا در وایرها مناسب است.
مشخصات کلی
The Prosonic FMU40 sensor is suited for non-contact level measurement in fluids, pastes, coarse bulk material and flow measurement in open channels or at weirs. The two-wire or four-wire compact transmitter can be used in applications with storage tanks, agitators, on stockpiles and conveyor belts. The envelope curve can be shown on the on-site display for simple diagnosis. Linearization function (up to 32 points) for conversion of the measured value into any unit of length, volume or flow rate.
Two-wire or four-wire instrument for continuous non-contact level and flow measurement.
