To provision a device, please provide the following information by emailing it to info@axistech.co
- Sensor name (typically the name of the location or tank name)
- Location (latitude/longitude)
- Offset (configuration instructions below)
- Sensor Display Limits, Minimum and Maximum level (configuration instructions below)
Configure the Offset
- Go to the Sensors -> Select the Sensor -> Sensor Setup Tab -> Display Settings Section
- Switch Offset Enabled to Yes;
- Fill the offset value in the Offset input field, the unit is indicated between the brackets next to Offset; the value should be the distance between the sensor and your chosen water level (0 water level could be the bottom of a water container, the Mean Sea Level, etc.);
- Click the Update button to confirm;
If the configuration is working, the offset value will be displayed in the Configuration section on the sensor’s information page. Please provide the offset value to us.
Configuring the Display Limits
The display limits of a sensor are the soft limits between which the water level will be displayed.
A sensor has two display limits – Minimum Level and Maximum Level. More particularly, if the water level is at or below the minimum level, the water level percentage will be 0% whereas if it is at the maximum level, the percentage will be 100%.
Admins and the owner of the organisation can configure the display limits in the following way:
- Go to the Sensors -> Sensor Setup Tab -> Display Settings.
- You’ll need to enable the Offset to access this feature.
- Make sure the Offset input field is filled. Read more about setting up the offset.
- Under the title Display Limits, put the Minimum display limit on the left input field while the Maximum on the right.
- Please provide us with the two display limits and click the Update button to confirm.
