Product Details

The EchoTREK high performance level transmitters are based on NIVELCO’s more than 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, 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 level transmitters can be used in multi-drop systems connected to a PC with the help of the SAT-304 HART®-USB modem or similar. EchoTREK are available with measurement ranges up to 25 m providing wide application possibilities. The 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.
