Wireless LPG Tank Monitor Sensor/Gas Tank Sensor with NB-IoT/LoraWAN module

The DF530 is one kind of ultrasonic liquid level sensor, which can detect the LPG tank liquid level by outside bottom installation without drilling holes. The tank thickness can be up to 10mm. (For special thickness, please contact with CNDingtek for confirmation.) The resolution is 1mm or 0.1%FS (the bigger value). The measurement ranges from 0-10 meters. It can be used for kinds of tanks, including iron, aluminium alloy, plastic and etc. It is applicable for automotive, oil station, chemical storage, LPG tank, and other industrial tanks to realize realtime monitoring of storage, online inventory management, statistics and estimation of production. It is optional with wireless module,like LoRaWAN, NB-IoT, Sigfox, GPRS, 3g/4g and etc. It is with inner battery. It is opened for customized design (OEM/ODM) on hardware or software.

Example of LoRaWAN:

The data from device will be collect from the DF530 Sensor will be received to the gateway then the gateway send the data to LoRaWAN network server through internet. After that the data from usage sensor of LoRaWAN network will be transferred through the internet to the application server. So the user can monitor the level status through web or mobile app.

It is already supported by some lorawan network server, like the Things NetworkMydevices and etc.

Glue

-

one component RTV Silicon Adhesive 703

 

 *: The couplant and glue is forbidden to delivery for airplane shipping or express shipping. So we do not offer them in the standard package.  

It is applicable if you can find one of the RTV silicon adhesive 703.  (if you can not find recommend glue, you can choose other glues, and their freezing time is less than 10 minutes )


6 Installation 

 

6.1 Preparation & Cleaning 

Before installation, please make sure the tank is horizontal so that the sensor can be

perpendicular to the liquid level. Otherwise, the sensor maybe can not get correct

value or even no value output.

Select one flat area on bottom of the container, and clean the dirt on the flat area to

make it smooth. If paint cover on the steel tank, please use the abrasive paper to

remove the paint cover. After cleaning, there is no any part between the transducer

and the bottom shell of the container.

6.2 Installation with butter

Put the probe into the probe holder and apply butter. To avoid air, put a little more

butter on the energy and tighten the back cover of the holder. Attach the probe to the


position marked in the previous step. Monitor the status values on the server to

ensure that the liquid level is correct. Tighten the three fixing bracket screws to

ensure that there is no gap between the probe and the tank bottom.


6.3 Data Checking

Check the data by online web page, the original data is liquid level in mm.
