Wireless LPG Tank Monitor Sensor DF530 Datasheet NB-IOT
- weight:200g
- Brand :CNDingtek
- Model:80*78*30mm
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.

5 Installation
Put the tank from vertical to horizontal, put glue on the transducer surface, stick them on the center of the tank bottom. Keep it for 5 minutes or more, then the glue solid the transducer.
Restore the tank to be vertical again.After about 12 hours later, the glue will be solid totally.
The controller box can be put near the bottom of tank. If there is not so much space for the wire route out, pleas use some bracket to lift higher the tank.
