Ultrasonic level meter

Sensor Function Analog

The analog output can be set through RS485, and the sensor can work in 8 modes. The specific reference is as follows:

Step 1: Connect to the host computer through serial port debugging assistant or modus debugging assistant.

Step 2: is to set a near point reference distance point.

Step 3:  set a far point reference point

Step 4:  is to set the output voltage or current of the near-point reference point.

Step 5: Set the output voltage or current of the remote reference point.

Step 6:is to set the analog output as the switch characteristic selection.

Step7: is to set the analog output as a linear output or switch output option.

Step 8: reset the sensor to make the new parameters take effect.

8 working modes of the sensor.

1: Open window mode by default

2: The window mode is closed by default

3: Single point mode is turned on by default

4: Single point mode is turned off by default

5: Single-point hysteresis mode is turned on by default

6: Single-point hysteresis mode is turned off by default

7: The presence or absence detection mode is turned on by default

8: The presence or absence detection mode is turned off by default

For the RS485 output type.

There are 2 kinds of working style,

One for auto measure, the sensor will measure the distance or level repeatedly, and the measurement period can be set by the UART. The measure result can be fetched every time.

The other style is power save mode when the sensor is sleep, until the sensor received the inquiry command with pre-code. Communication protocol is Modus-RTU.

For example, the measure result can be read by access the register 0x101 by Modbus protocol.
