(less is more) ECHOTEL Ultrasonic Level Switches ® The more you rely on ECHOTEL ultrasonic level switches, the less you will worry if a tuning fork is up to the job of providing the outstanding quality, reliability and overfill prevention your facility needs. ECHOTEL® ultrasonic switches provide continuously accurate and reliable level control that outperforms tuning fork technology. While tuning forks have been widely adapted by the industry, the fact is ECHOTEL ultrasonic switches offer more benefits More Performance HI LOW ECHOTEL® Tuning Fork Reads All Liquid Densities • ECHOTEL can read any liquid density, even below 0.6 SG, to provide continuously accurate and reliable level control – and superior overfill prevention. • Unlike tuning forks, which require you to configure a DIP switch to ensure density calibration – and may n ot be able to measure low-density liquids – no density adjustments are required with ECHOTEL. More Efficiency and Versatility Dual-Point Capability Dual-Point Capability Dual-Point Capability • In addition to the ECHOTEL Model 961 single-point option, the ECHOTEL Model 962 provides dual-point capability to give you two-point measurement from the same unit. • In contrast to tuning forks that require the purchase and installation of two units – and two separate tank openings – you only need one switch and one tank opening to measure dual-point level with ECHOTEL. Remote Mount Capable Remote Mount Up To 150 feet • While tuning forks require top-of-tank switch modification, ECHOTEL gives you versatile access and ease of control, with remote mounting capability that can be up to 150 feet away from the transducer. Get and Le Dual-Point Remote Mounting Switch Point < 6” Extensive Selection of Transducer Mat Advanced Self-Testing No Density Calibration Required More Information and Diagnostics Malfunction Level Alarm Two Separate Relay Outputs • ECHOTEL ultrasonic units allow you to configure two separate relay outputs for diagnostics and level alarms to give you more information – and ensure compliance with industry safety guidelines. Advanced Diagnostics Capabilities Red Light Indicates Fault • ECHOTEL also offers advanced diagnostics capabilities compared to tuning forks, with thorough testing of electronics, transducer, piezoelectric crystals and for the presence of electromagnetic noise. Transducer Gap More Advanced Technology Transducer Gap Receive Crystal Receive Crystal Transmit Crystal Transmit Crystal Ultrasonic Gap Technology • ECHOTEL uses pulsed signal technology that only transmits pulsed sound waves across the transducer gap when liquid media is present, so density does not matter. t More Performance – ess Worry – with ECHOTEL terials Green Light Indicates Normal Operation Echotel Tuning Forks Limited • When liquid is present in the transducer gap, a receive crystal senses the ultrasonic signal from the transmit crystal and converts it to an electrical signal to indicate liquid is present. With ECHOTEL ultrasonic level control, you’ll be assured of superior overfill prevention across your tank inventory. It’s a simple equation of more performance and less worry that you can count on from Magnetrol ® – the level control experts.
