Ultrasonic flow-meter for liquids
Echotel® 355 MAGNETROL

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 and false echoes exist.
