Echotel® 335 - 1

Echotel® Model 335 Non-Contact Ultrasonic Transmitter for Level, Volume, or Open Channel Flow Echotel® Model 335 is a high performance, non-contact ultrasonic transmitter for liquid level, volume, and open channel flow measurement. The extremely powerful and flexible software incorporated in the Echotel 335 results in virtually unsurpassed measurement performance. Advanced digital signal processing enables the 335 to perform in applications involving in-tank obstructions, light foam and agitation. The custom graphics LCD display module facilitates complete setup and configuration, and displays level, volume, flow and temperature, as well as diagnostic information. LEDs reflect the strength of the echo. A bar graph displays echo strength from the return signal, or tank level as a percentage of span.

TECHNOLOGY Non-contact ultrasonic level technology is a proven method for accurate liquid level measurement. This technology features the ability to measure the level or volume of the fluid without making physical contact with the material. This is especially important in applications containing corrosive materials, suspended solids or coating media. The level measurement is made by emitting an ultrasonic pulse from the transducer and measuring the time required for the echo to reflect from the liquid surface and return to the transducer. The powerful electronics measure the time of the...
