Echotel® 355 - 1

ECHOTEL® 355 Ultrasonic non contact transmitter for level, volume or open channel flow DESCRIPTION The Echotel® 355 is an integral mount, high performance ultrasonic non contact transmitter for liquid level, volume and open channel flow measurement. The electronics are housed in a single compartment cast aluminium or Lexan® 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 application difficulties like turbulence and false echoes exist. FEATURES • 2-wire, intrinsically safe loop powered • Fast and easy configuration via 2 x 16 character display and 4-pushbutton keypad • False target rejection identifies true echo from liquid surface • Common tank shapes and 20-point custom table for volume calculations. • Flume/weir primary elements and generic equation for open channel flow. • Two 7-digit totalizers for flow: - resettable - continuous totalizer ® Consult factory for proper model numbers and classifications. APPLICATIONS • Open channel flow flumes and weirs • Paint, ink and solvent tanks • Chemical storage • Thick and viscous media • Batch and day tanks AGENCY APPROVALS Worldwide level and flow solutions

Echotel® 355 - 2

The level measurement is accomplished by emitting an ultrasonic pulse from the transducer face and measuring the travelling time between sending this pulse and its reflected echo from the liquid surface. Since the speed of sound is temperature dependant, the transducer also measures ambient temperature to compensate for the changing velocity. Measurement Range Calculations Ultrasonic non-contact measurement transmitters are typically rated for their maximum rangeability. Depending process conditions, their maximum range needs to be reduced for getting an optimal measuring result. Use below...
