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. Up to 6 m (20 ft) range F E AT U R E S • 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 Agency ATEX Open channel flow flumes and weirs Paint, ink and solvent tanks Chemical storage Thick and viscous media Batch and day tanks ➀ Consult factory for proper model numbers and classifications.

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 chart to calculate the realistic rangeability of your application. 6 m (20 ft) x Performance multiplier (see table below) as per described process condition. OPERATING PARAMETER SURFACE AGITATION: Surface agitation or waves can degrade the performance. Moderate agitation results in only slight degradation of performance. The worst case is when the surface is a good reflector, but in the wrong direction. VAPORS AND STEAM: Vapors can cause problems when the liquid process temperature is well above the temperature of the airspace. The greater the difference, the more expected vapor problems. The problems result from condensation or layering in the sound path, both of which attenuate the sound signal, and degrade performance. If a vent is used, be sure that it is well away from the transducer. BEAM SPREAD INTERFERENCE: It is recommended that no obstructions, such as ladder rungs, fill pipes, support struts, etc, be allowed within the 10° ultrasonic beam. If an obstruction is unavoidable, make it as far as possible from the transducer. Interference from agitator blades is only an intermittent interference that usually has little effect on performance. A special software algorithm can also help suppress false echoes from agitator blades that are within the beam angle. FOAM: Foam can attenuate the ultrasound and render the system inoperative. If possible, moving the transducer to an area in the tank where there is less foam will improve the performance. Thick, heavy-density foams can sometimes produce a reflection from the top of the foam. The multipliers shown at right are general guidelines. For further assistance consult the factory.
