Echotel ® Model 355 is a two-wire, loop-powered, noncontact ultrasonic transmitter that performs liquid level, volume, and open channel flow measurement. Model 355 Transmitters feature a powerful 60 kHz ultrasonic transducer and advanced digital signal processing to reliably measure out to a 20 feet (6 m) maximum range.
The Model 355 provides unsurpassed ease of configuration with either the menu-driven 4-push-button, 2-line ¥ 16-character display, HART® digital communications, or PACTware™. This enables a complete configuration to be performed via the local user interface, or remotely with the extra capability of capturing echo wave forms, and viewing trend data, diagnostic conditions, and all transmitter configuration parameters.
The integral mount electronics are housed in either a cast aluminum housing or Lexan® thermoplastic housing. The intelligent electronics analyze the ultrasonic echo profile, apply temperature compensation, reject echoes from false targets, and then processes the true echo from the liquid surface. This results in an extremely reliable measurement even when applications difficulties like turbulence, rapid level changes, or echoes from false targets exist.
The 60 kHz ultrasonic transducer is offered in polypropylene, or Kynar® Flex for superior performance in harsh environments. These powerful transducers feature a 10° conical beam and 10″ (250 mm) blocking distance to maximize measurement capabilities in a wide variety of applications.
