DF550 wireless GPRS/GPS/GSM fuel tank level sensor for truckWidely used to be a fuel level sensor, water level meter and other liquid level sensor.The F550 is one type of ultrasonic level sensor which measure the air height ,
in the container directly and calculate the level height ,
based on the total height of the container.
The resolution is 1mm or 0.1%FS (the bigger value).

It is applicable for the close container or open container.
Furthermore it can calculate the volume of the container or the liquid.
As with RS485, it is easy to integrate into the embedded system or SCADA.

In order to realize remote monitoring, there are
wireless version for F550, including zigbee, Wifi, GPRS, 3G.
Furthermore, GPS module is one optional for the F550.
As a result, F550 can be used as gps tracker also.

InstallationAfter installation, the user should input the total heighttank type and other parameter
in order that the sensor can calculate the liquid height, volume and etc.

Q1 Can we use the DF550 to detect solid level / height?
Yes, the DF550 is air distance sensor, solid level sensor and liquid level sensor.
It can directly measure the distance from transducer to the solid/liquid.
Then it can draw out the solid height or liquid height.
Formula is solid height = total height- air height.
Q2 Can the DF550 use for chemical tank?
Yes, the DF550 can use for chemical tank.
And it has PTFE/PVD version which is good for erosive environment.
Q3 Can the DF550 be used for open cover case?
Yes, it can use for covered or open case. E.g.
It can be used to detect tide / river level or solid height.
Q4 What is the IP level for the DF550?
It is IP66.
Q5 Can the DF550 be used for high temperature case?
No, if more than 70, the DF550 maybe work out of control.
Q6 Is the DF550 with ATEX certificate?
No, it is qualified with CE EMC, RTTE, Rohs. But not with ATEX certificate.
Q7 Can the DF550 used to measure powder height?
Yes, If the powder is stable on the ground, not floating in air. It can measure.
Q8 Can we use the DF550 for covered container?
Yes, it can work. But the user should drill hole at top.
Below is the recommend installation for underground tank.
