The Eurosens Difference T4 controller is a 4-channel analog-digital converter. Usually it is used as a part of eurosens Difference onboard weighing system.

1. Acquiring data from a sensor with an analog or pulse output.
2. Storing calibration tables for all sensors, with 1–3 tables assignable to each sensor. When a pulse output is connected, a conversion factor is used instead of a table.
3. Calculation of data using specified calibration tables.
4. Transmission of the resulting data via the RS-485 interface. Data is transmitted using the MODBUS or LLS protocol.

This device can be used to monitor fuel dispensers—the fuel dispenser’s flow meter count output is connected to one of the Difference T4’s count inputs. Thus, all four fuel dispenser hoses can be connected to the four inputs of the Difference T4.
