LDI ROW Non-Contact Oil Detector X-Series Integration Guide


The LDI ROW Non-Contact Oil Detector is an autonomous non-contact sensor for the detection of oil on water in industrial and environmental applications. It easily integrates with NexSens X-Series data loggers using the RS-485 sensor interface.

An LDI ROW Stainless Steel Non-Contact Oil Detector is illustrated on the right with a line pointing to the left where an X3 is transmitting data waves to a cloud above which has a line to a phone screen on the far left which displays fluorescence signal data on the screen in the WQData LIVE mobile app view.

Sensor Setup

Before the sensor can be deployed, it must first be set up through the LDI ROW Configurator Software. Follow the manufacturer’s guidelines for sensor setup.

 

Connecting with X-Series Loggers

Next, the LDI ROW will need to be set up for the X-Series logger using CONNECT software. If you have not yet done so, set up the project in WQData LIVE.

  1. Connect the sensor using the supplied cable to one of the open sensor ports on the logger and note the port number.
  2. Plug the X3 into the USB port of the computer and power it on with the AC power cable.
  3. Open CONNECT and select the SENSOR tab.
    Open CONNECT and select the SENSOR tab.
  4. Click Add and select LDI from the Manufacturer drop-down. Then select the appropriate model.
  5. Adjust the Modbus address if needed and select the port number.
  6. Select either Continuous or Switch in the Power drop-down.
    1. Switch is recommended for the LDI ROW.

  7. Select Save Sensor Profile.
  8. Complete the setup for all other sensors, and then click Save.
  9. Name the Sensor Profile List and select Ok.
    Save Sensor Profile List.
  10. Complete system setup by clicking Deploy.

  11. Confirm that data is being transferred to WQData LIVE at the next interval (default is 10 minutes).

 

Mounting

Deployment setups will vary based on the platform, application, and site location. For general buoy mounting, see below.

 

Buoy-Based Deployments

First, follow the appropriate User Guide in the Knowledge Base for buoy assembly. Next, use the CB-ROW-M to mount the sensor on the buoy’s solar tower following the steps below.

  1. Attach the sensor bracket to the mounting arm.
    Attach the LDI ROW to the mounting arm bracket.
  2. Be sure to counterbalance the system in order to prevent tipping. Counterbalance weight should equal the weight of the sensor and mount.
