H&B Sensors offer two versions of Ultrasonic Level Transmitter. The ECHOTEL® 335 and ECHOTEL® 355 are both intergral mount, high performance non contact Ultrasonic Level Transmitters which can be used for level, volume or open channel flow measurement. Both models are available with either a Polypropylene (PP) or Kynar® (PVDF) transducer.

The ECHOTEL® 335 has a maximum measuring range of 8 metres and is suitable for process temperatures between -30°C and +90°C. The 335 model features a 4 to 20mA output and SPDT relay which can be used for level control, alarm diagnostics or remote flow totalisation. The aluminium housing encloses a LCD indicator which clearly displays the echo strength.

The ECHOTEL® 355 has a maximum measuring range of 6 metres and is suitable for use with process temperatures between -40°C and +80°C. The 355 model is available with or without HART® communication and be specified with either ATEX Exia or ATEX Exd approvals. A 2-line x 16 character LCD display and 4 button keypad is enclosed inside the aluminium or Lexan® plastic housing allowing for fast and easy configuration.
