level sensor directions for use

capacitive fuel sensor is according to the principle of capacitance, using rf capacitor jump to change measuring technology to realize the measurement of height of liquid. Output signal with high level change and continuous change, no steps, high accuracy, high reliability. The elastic components, is no moving parts, impact resistance, easy installation, can be installed on all occasions for gasoline, diesel oil, oil level of the hydraulic oil and other various liquid for accurate measurement and control.


The liquid level meter response:

ASCII : *RFV01000.0197

RFV as for reading level to return to sign.

For the current oil level sensor 01 ID number.

000.01 to the current oil a value, percentage said, high for 100.00. Fixed to XXX. XX form expression, less than a to zero added. Such as 012.21, 12.21% said.

98 for collation and

Hex: 2 A 52 46 56 30 31 30 30 30 2 E 30 31 39 38 0 D 0 A


2. the current level of read AD value

By a terminal or computer to send to level meter command (a filter) :

ASCII : $!RY0151

Hex: 24 52 59 30 and 35 21 31 0 D 0 A

Level meter reply:

ASCII : *CFV0100FA32B6

FA32 for the current AD value, for less than 6 bytes fill 0 instead of, FA32 for the current oil a AD value of ASCII said hexadecimal, which means that the current oil a value of 0 for xFA32.

this AD value of oil a 0% ~ 100% change and the corresponding 000000 ~ ~ of AD value FFFF

3. Set level instrument ID

By a terminal or computer to send to level meter command: (ID 0-99)

ASCII: $!ID0133

ID for command

01 for ID value

Hex: 24 and 31 and 33 49 44 30 0 D 0 A

The liquid level meter response:

ASCII: * SID01OKOKOK39 says success

* SID01NONONO42 said failure

An 01 result indicates set ID value, OKOKOK said set success, ONONON says setting failure.

Hex: 2 A 53 49 44 30 31 4 F 4 B 4 F 4 B 4 F 4 B 33 39 0 D 0 A

2 A 53 49 44 30 31 4 E and F 4 E and F 4 E and F and 32 0 D


4. Set filter coefficients:

By a terminal or computer to send to the level of command

ASCII: $!Z40134

Z for command

01 for ID value

4 for filter coefficients, optional parameters for: 0,1,2,3,4,5,6,7,8,9 the rest parameters is invalid

Hex: 24 21 5 A 34 30 31 33 34 0 D 0 A

If the old car to be removed the original sensor. The installation of the new car directly installed;

② before installation, please check the attachment: rubber pad, fixed screws are complete and consistent;

③ the tank by way of a good way to install a good hole, hole size before the 30-40mm diameter can be;

⑤ the sensor inserted into the tank lock can be fixed screws;

⑥ according to the definition were connected to the power line and communication lines; ⑦ check the line is normal, you can then connect to the fuel tank,

⑧ sensor installation location (before and after the left and right) should be as close as possible to the tank center, thereby reducing the car in the uphill when the oil caused by the tilt and oil surface fluctuations in its shadow
