    • Weight:No parameters
    • Brand :ultrasonic Fuel Level Sensor
    • No.: DF520

    The DF520 is non-touch ultrasonic level sensor, which is applicable for fleet fuel management for generators, engine fuel tank, fuel shipping tank, or construction engine fuel tank

    1. Detailed information

    1.Overview

    The DF520 is non-touch ultrasonic level sensor, which is applicable for fleet fuel management for generators, engine fuel tank, fuel shipping tank, or construction engine fuel tank. It works for kinds of tank, aluminium alloy, plastic, iron, stainless steel and etc.

    For the standard version, it is one type of ultrasonic level sensor which measure the liquid level without drilling hole on container. The resolution is 1mm or 0.1%FS (the bigger value). The measurement ranges from 0-2 meters.

    The standard version work for up to 3mm thickness tank. If your tank thickness is more than 3mm, you can try the enhanced version DF521, which can work for 10mm thickness tank, such as construction machine and etc.

    For the DF520/520, there is wireless option available. It is integrated with GPRS+GPS (or WCDMA+GPS), so it can upload data to server directly.  Also It supports to upload data to third party IOT platform, such as Thingspeak™.  

    It is opened for customized design (OEM/ODM) on hardware or software.

    Notes: The brand name Thingspeak is owned by Thingspeak company.
