2018 no drill hole ultrasonic level sensor for tank level measurement with wireless to iot platform or gps tracker

1.  Overview the ultrasonic fuel / water level sensor

The DF520 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).It is applicable for the close container or open container which thickness is less than 3mm. Steel tank or plastic are applicable. Output is optional for 0-5V, RS232 and RS485, it is easy to integrate into the embedded system or SCADA.In order to realize remote monitoring, there are wireless version for DF520, including zigbee, Wifi, GPRS,3G by working with our wireless module. Furthermore, GPS module is one optional for the DF500.

Notes: If there is labels on sensor for pin definition, please act as the labels.

 

 

 

 

Press the two button at the same time for more than 3 seconds, it will come into the installation mode. In this mode, there are two screens. One is the level value in cm. The other is the signal status. For the signal status, it is 0-2. 2 is the best status, you can directly use this position for the final installation point. 1 is the secondary option when you can not find the signal status of 2 on this container. 0 is bad point to install, do not recommend to install on point with status 0

7.3 Installation with double faced tape

If it is aluminium alloy or plastic tank, please use the double faced tape to install.

 

7.4 Installation with glue


Glue is applicable for steel tank as well as aluminium alloy or plastic tank.
Put glue on the transducer surface, stick them on the position you remarked at previous step. Monitor the status value on the LED display, make sure it is 2 (1 is secondary option if no 2), fasten the transducer with the container. Keep it while the glue solid the transducer.
Install the transducer protection part and fasten the transducer with the tie.

 

7.5 Routing wire

Use insulative tape to protect the connecting part of the transducer and the extended cable as well as the signal, power connection part.
Fasten the cable around the device or vehicle, make sure to avoid the heat part.
