The EasyTREK SP–500 Pro series Ultrasonic Level Transmitter for Liquids embodies NIVELCO’s forty years of experience in ultrasonic level measurement. The devices are IP68 rated, their transducers and processing electronics combined in a single unit. EasyTREK transmitters use HART® 7 communication, they can be used in multidrop systems connected to a MultiCONT process controller/display or a PC via UNICOMM HART®–USB modem or similar. Transmitters can also be programmed remotely with the Handheld Field Communicator; They can be connected wirelessly to a computer via the SAT-504 Bluetooth® HART® modem. EasyTREK SP–500 Pro instruments are smaller in size, the maximum measuring range has been extended and the minimum measuring range has been reduced.

What are the General Features of Ultrasonic Level Transmitters?
EasyTREK ultrasonic level transmitters can be used not only to measure the level of liquids (fluids), but also for flow and tank volume measurement. Ultrasonic level measurement technology is based on the principle of measuring the time it takes for ultrasound pulses to travel the distance from the sensor to the level to be measured and return. The echoes returning from the surface of the medium to be measured reach the sensor surface after the flight time of the ultrasonic pulse. The time of flight of the reflected signal is measured and processed by the electronics and then converted into distance, level, volume or flow proportional data using customizable tank sizes or pre-programmed channel/sluice parameters. EasyTREK ultrasonic level transmitters use NIVELCO’s built-in SenSonic series transducers with a full beam angle of 5 to 7 degrees, connected to intelligent electronics with QUEST+ advanced signal processing algorithm. The intelligent QUEST+ process adaptive signal processing software system enables the electronics to identify and verify the liquid surface signal, providing reliable level monitoring.
