F500 ultrasonic fuel level sensor ultrasonic level transmitter water tank level indicator with 0-5v output no drilling hole

1 Overview

The DF500 is one type of ultrasonic level sensor which measure the liquid level without drilling hole on container. The resolution is 1mm or 0.1%FS (the bigger value).It is applicable for the close container or open container which thickness is less than 5mm. Steel tank or plastic are applicable. Output is optional for 0-5V, RS232 and RS485, it is easy to integrate into the embedded system or SCADA.In order to realize remote monitoring, there are wireless version for DF500, including zigbee, Wifi, GPRS,3G by working with our wireless module. Furthermore, GPS module is one optional for the DF500.

Pin 1: Red Line: V+,
Pin 2: Black Line: GND
Notes: If there is labels on sensor for pin definition, please act as the labels.

Press the two button at the same time for more than 3 seconds, it will come into the installation mode. In this mode, there are two screens. One is the level value in cm. The other is the signal status. For the signal status, it is 0-2. 2 is the best status, you can directly use this position for the final installation point. 1 is the secondary option when you can not find the signal status of 2 on this container. 0 is bad point to install, do not recommend to install on point with status 0

7.3 Installation with double faced tape

If it is aluminium alloy or plastic tank, please use the double faced tape to install.

Then use the tie to fasten the transducer with the container.

7.4 Installation with glue

Glue is applicable for steel tank as well as aluminium alloy or plastic tank.
Put glue on the transducer surface, stick them on the position you remarked at previous step. Monitor the status value on the LED display, make sure it is 2 (1 is secondary option if no 2), fasten the transducer with the container. Keep it while the glue solid the transducer.
Install the transducer protection part and fasten the transducer with the tie.

7.5 Routing wire

Use insulative tape to protect the connecting part of the transducer and the extended cable as well as the signal, power connection part.
Fasten the cable around the device or vehicle, make sure to avoid the heat part.

8 Protocol

8.1 Baud Rate and Bits

The default baud rate is 9600bps, one start bit, eight data bit, one stop bit, no checksum bit.

8.2 Packet from Device to Sensor

Header: $! In ASCII or 0x24 0x 21 in Hex.
Command: to show which kind of command.
ID: sensor id number, from 01 to 99 in ASCII. Or 0x30 0x31 to 0x39 0x30 in Hex.
Checksum: Sum of bytes from header to id, then select the low 8 bit, finally convert to ASCII and show in Hex. E.g. If sum is 0x0356, then low 8 bit is 0x56, to ascii, the value is 56(0x35 0x36 in Hex).
End: 0x0D 0x0A.

8.3 Packet from Sensor to Device

Header: * In ASCII or 0x2A in Hex.
Command: to show which kind of command.
ID: sensor id number, from 01 to 99 in ASCII. Or 0x30 0x31 to 0x39 0x30 in Hex.
Data: Replied data.
Checksum: Sum of bytes from header to data, then select the low 8 bit, finally convert to ASCII and show in Hex. E.g. If sum is 0x0356, then low 8 bit is 0x56, to ascii, the value is 56(0x35 0x36 in Hex).
End: 0x0D 0x0A.

8.4 Read LevelAD Value

Request: From device to sensor.
ASCII: $!RY0151
Hex: 24 21 52 59 30 31 35 31 0D 0A
$! is header, RYis command, 01 is sensor id, 51 is end.

Reply: From sensor to device
ASCII: *CFV0100FA32B6
Hex: 2A 43 46 56 30 31 30 30 46 41 33 32 42 36 0D 0A
* is header, CFV is reply command. 01 is sensor id. 00FA32 is AD value for level. 00 is the padding to fulfill 6 bytes of data section required. FA32 is the level AD value. Level 0%~100% equals with 000000~00FFFF.

8.5 Read Level Percent

Request: From device to sensor.
ASCII: $!DO0139
Hex: 24 21 44 4F 30 31 33 39 0D 0A
$! is header, DO is command, 01 is sensor id, 39 is end.

Reply: From sensor to device
ASCII: *RFV01000.0198
Hex: 2A 52 46 56 30 31 30 30 30 2E 30 31 39 38 0D 0A
* is header, RFV is reply command. 01 is sensor id. 000.01 is the level value in percent. Max is 100.00.

Notes: The protocol maybe update without notification. Please contact with us for the latest protocol.

9 Analog Value Interpretation

For the analog output, it is 0-5V map to 0-100cm linearly. For example, if the output is 2.5V, then the
level is 50cm.
Please notified that, there is voltage lost on the cables. So if the controller box output 2.5V, maybe
your device can only get 2.4V after the signal cable transmission.
