Ultrasonic Compact / EchoTREK® for Liquids



The EasyTREK and EchoTREK high performance level transmitters are based on NIVELCO’s 35 years of experience with ultrasonic
level measurement. Whether for liquid level measurement in sumps or tanks, for tank contents measurement, or open channel
flow measurement, EasyTREK & EchoTREK transmitters provide the answer. Installed on the tank roof, or above the liquid surface
to be measured, the transmitters give analogue output proportional to liquid level or transmit HART® digital data. 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 EasyTREK high performance level transmitters are IP68 rated units have their transducer and processing electronics incorporated in one single housing. The EasyTREK transmitters utilize HART® (HART® 7 in case of SP-500 series) communication so they
can be used in multidrop systems connected to MultiCONT process controller/display, or to a PC with the help of the UNICOMM
HART®-USB modem or similar. The transmitters can be connected wirelessly to a PC with the SAT-504 Bluetooth® HART® modem.
The members of the new EasyTREK SP-500 series can be recognised from the more compact size, the increased maximum
measuring range and the decreased minimum measuring range and can be remotely programmed also with Handheld Field
Both models can be used in multi-drop systems connected to NIVELCO’s MultiCONT process controller/display, or to a PC with
the help of the UNICOMM HART® USB / RS485 modem or similar. EasyTREK and EchoTREK are available with measurement
ranges up to 25 m (82 ft) providing wide application possibilities. Both ultrasonic level transmitters are using NIVELCO’s
established 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.
