Page 5: Rs485 Interface
RS485 interface allows for connection of multiple sensors to a single terminal (pictures 1 and 2). All of the MIELTA terminals support connecting up to 8 sensors or other peripheral devices on the RS485. Picture 1. Network topology "star". - Page 6 Picture 2. Network topology "bus". Network topology «bus» is used for connecting multiple sensors to a single terminal on the distance up to 100 m. In this case it is necessary to connect a terminal resistor of 120 Ω 0,25 W near the furthest sensor in the network. If the network length in greater than 20 m it is recommended to use shielded twisted pair.

Page 8: Installation
Installation The sensor is mounted in the highest point of the tank and above the lowest point of the tank. The mounting surface should be horizontal. Picture 3. Sizes of FLS mounting plate. The center hole should have a diameter at least Ø25 mm. The screw holes’ diameters are chosen according to the material of the tank. - Page 9 Picture 4. Sizes of FLS. Installation steps: 1. Select the installation place and clean it. 2. Mark the holes according to the installation plate sizes, drill and clean them. 3. Measure the depth of the tank from the bottom to the installation place. 4.
- Page 10 When necessary to avoid obstacles in the complex shaped tanks, the measuring rod might be bent. Bending is done using a pipe bender with the bend radius not shorter than 250 mm. Bend angle should be no more than 15° (picture 5). Picture 5.

Page 12: Configuration
Configuration 5.1. Connection For configuring the FLS the MieltaDM Android application is used. Configuration can only be done using a smartphone with an NFC- module. For the appropriate operation of the configurator the user should allow all the requested permissions. When the FLS is unpowered, the user can only read the current configuration. - Page 13 FLS, company name and the reason for the master password request with the official signature and/or stamp of the company. If the correct password is provided, the parameters window is opened, in which all the FLS parameters are displayed.

In the upper right corner the “Link” indicator is located. It lights green when the sensor is connected to the configurator and a new data packet is received. When the connection is not active all the user’s actions are stored in the tasks queue, the length of which is displayed in the “Tasks”... -
Page 15: Main Settings
5.3. Main settings There are the following settings available in the configurator: RS-485 bus speed (9600, 19200, 38400, 57600, 115200); RS-485 bus address (0..254); Output mode: No automatic output; Automatic output in binary format; Automatic output in character format; ... -
Page 16: Calibration
5.4. Calibration Before usage the FLS should be calibrated for the empty and full tank. These values will correspond to 0% and 100% accordingly. The calibration should be done in the following way: 1. Cut the measuring tube and the central electrode to the length 20 mm shorter than the depth of the tank;... - Page 17 mounting plate); 5. After waiting for the level to stabilize, save the calibration value for the full tank. For that press the “Set value” button on the “Full tank” parameter; 6. Get the FLS out of fuel and wait for it to drain for about 5 minutes; After waiting for the level to stabilize, save the calibration value for the empty tank.

5.5. Service settings The service settings menu contains following settings: Changing the password; Updating the FLS firmware (the firmware update file is selected from the smartphone’s memory and should be downloaded beforehand); Other commands: Restart the sensor; ... -
Page 19: Taring
Taring Sensor’s taring – creating a mapping table from the FLS output to the actual volume of the fuel in the tank. The taring is done separately for separate tanks and is necessary to convert the output of the FLS to the fuel volume in liters. The more complex the shape of the tank is, the more taring points should be done. - Page 20 Pour the necessary volume of fuel into the tank, wait for the level to stabilize and write the volume of added fuel and the output of the sensor to any data storage, for example, an Excel table. Repeat those steps, sequentially adding fuel to the tank by the selected taring step and writing the values until the tank is full.

Page 21: Transportation And Storage
Transportation and storage FLS should be stored in a storage facility with the temperature from -20°С to +50°С and relative humidity not higher than 85%. The sensor should not be exposed to water or other liquids. Transporting of the sensor should be done in a package. Warranty The manufacturer guarantees the operating of the FLS for 3 years since the day of purchase if the storage, transportation, installation and usage requirements are met. -
