New Two-Wire Non-Contact Ultrasonic Transmitter

The new Echotel® 355 two-wire, loop-powered, non-contact ultrasonic transmitter from Magnetrol International (Belgium) measures liquid level, volume and open channel flow with unsurpassed performance and ease of operation. This new low-cost, integral mount unit features a powerful 60 kHz ultrasonic transducer and advanced digital signal processing to reliably measure out to a 6m maximum range.

The Echotel® 355 can be configured locally, with the menu-driven four-pushbutton LCD display, or remotely, with HART® digital communications or PACTwareTM, with the extra capability of capturing echo wave forms, 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.

Volume and open channel flow configuration has never been easier than with the Echotel Model 355 Transmitter. Volume applications are easily configured by selecting the tank shape and inputting 1 – 3 tank dimensions. Open channel flow configurations are accomplished by merely selecting one of the 35 flume and weir curves stored in the transmitter, and setting multipliers for the resettable and non-resettable 7-digit flow totalizers.
