The EchoTREK is an intelligent compact ultrasonic level transmitter with 4 – 20 mA output offering HART®protocol as option. Local reading is ensured by a plug-in display which can be removed if displaying is not needed. Four keys provide for programming, both display and keys are located under a removable cover. The unit is tank-top mountable only.

The level transmitters can be used in multi-drop systems connected to NIVELCO's MultiCONTprocess controller / display, or to a PC with the help of the UNICOMM HART®-USB / RS485 modem or similar. EchoTREK are available with measurement ranges up to 25 m providing wide application possibilities. The ultrasonic level transmitters are using NIVELCO'sestablished SenSonic range transducers with a full beam angle of 5 to 7 degrees connected to the intelligent electronics featuring the QUEST+ advanced signal processing algorithm
