EchoSmart™ Sludge interface level measurement Ultrasonic measuring system with submerged sensor (Sonar) EchoSmart™ sensors EchoSmart sensors generate and process the ultrasound signal for real time measurement with maximum flexibility of the liquid/solid interface. They have greater signal control and the performance of the control algorithms, specifically developed and field tested, has been confirmed in the U.S. and around the world. EchoSmart Network Options available: • EchoSmart sensor in conjunction with the EchoSmart controller • An EchoSmart network is composed of between 2 and 128 sensors connected together with a wired or wireless network • EchoSmart sensor in conjunction with the power supply unit (remote programming via EchoSmart Console SW) • RS 485 or Ethernet connections are available for wired networks. EchoSmart Networks • Network interconnection of up to 128 EchoSmart sensors • Communication via RS-485 or Ethernet • RF compatible ZigBee network integration Easy to use • Large display with intuitive screens for quick entry of parameters • Soft key operation with guide for all settings • Initialisation and automatic calibration for quick start-up with no process interruption • The ZigBee wireless system is also available and is the ideal choice, given the enormous reduction plant engineering (wiring and piping) costs. Characteristics – Up to 16 EchoSmart sensors can be connected in a network with a single EchoSmart controller with optimised operation and significantly reduced costs – ZigBee with “self-healing” mesh technology ensures reliable communication by eliminating unnecessary piping and wiring costs
