F300 flange installtion Stainless steel capacitive level sensor 0-5V analog RS232 RS485 digital output
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.

Notes: If there is labels on sensor for pin definition, please act as the labels.
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.
The default baud rate is 9600bps, one start bit, eight data bit, one stop bit, no checksum bit.

Feedback from client
1. Can I use it with gps tracker?
Yes, it support any gps tracker with 0-5V analogue input or RS232 input. If RS232 interface, the gps tracker need to do integration with our sensor protocol.
2. Which is the gps tracker list it support?
Any gps tracker with 0-5V analogue input and RS232 input. such as A300, VT310, MVT400, MVT600 and etc.
3. What is the resolution?
0.1mm. If multiple with section area, we can conclude the liter resolution, normally less than 1 liter for vehicle tank.
4. Can we measure the liter changing with it?
Yes, create one map between level and liter, then can draw liter changing.
5. Why is it expensive than other floating sensor?
Because capacitance is more stable and higher resolution than floating sensor. So do not compare with different type of sensor. Just compare with other capacitance sensor, our will be the most cost-effective one.
6. Do you have support for integration with our application?
Yes, we have EE and SW engineers team to support for you with integration of our product.
7. Is it safe for using with gasoline?
Sure, we have ExtdIIT certification.
8. Can we cut short to adopt our tank?
No, it does not support user cutting short. We have another model F330 support customer resizing.
