Product Description
F300 capacitive level sensor liquid level measurement sensors diesel tank level sensor
1 overview
The DF300 is one kind of high resolution capacitance level sensor, the resolution is 0.1%FS or 1mm (the bigger value). It is made of stainless steel 304 (optional for 316). It is robust for vibration, such as vehicle, generator, railway train and etc. Also it is good for bad quality liquid, such as sewage or other water.
It is applicable for the close container or open container or pool or river. As with RS485, it is easy to integrate into the embedded system or SCADA.
In order to realize remote monitoring, there are wireless module optional for DF300, including zigbee, Wifi, GPRS, 3G. Furthermore, GPS module is one optional for the DF300. As a result, DF300 can be used as gps tracker also.

7 Installation & Cases
7.1 Installation
Before the installation, please check sensor and accessory,such as rubber blanket,screws and tools for drilling hole.
If your tank have a old probe sensor ,you need to remove ,then put the new sensor on your tank . Otherwise,you can directly go to next step.
Drill big hole on the tank according to the following diagram, diameter is 30-40mm. Then put the flange on the big hole, and position the small screw, then drill small hole for screw.
Put the glue on the rubber blanket ,then put it under the flange
Put the sensor in the tank at first ,screw to fix it
Connect the power line and signal line according to the definition
Notes: Mounting Position of the sensor should be close to the center of the tank, which can reduce the oil level slope and oil level wave when the vehicles are uphill and downhill.
The sensor is automatically calibrated, so no need to do special calibration.
Put the glue on the rubber blanket ,then put it under the flange
Put the sensor in the tank at first ,screw to fix it
Connect the power line and signal line according to the definition
8 Protocol (for RS232/485/wireless version)
The default baud rate is 9600bps, one start bit, eight data bit, one stop bit, no checksum bit.
