Characteristics of the electronic calculating and indicating device
In Table 1 the general characteristics of the electronic calculating and indicating device are presented. The construction of the electronic calculating and indicating device is recorded in the Documentation folder no. TC12658-1.
$ \mathrm{Sigma}^{3} $ is a panel mounted or rack mounted flow computer designed for fiscal measurement, custody transfer and batch loading of petroleum products in liquid phases. $ \mathrm{Sigma}^{3} $ can be configured in single or multi stream operation with dual pulse input.
It consists of 8 channels of pure HART and 8 channels of analog I/O with HART.
16 channels for digital input are also available.
Sigma $ ^{3} $ is equipped with a 7" touch screen for easy setup and control. Serial and Ethernet communication ports and runs in a Linux environment on ARM architecture.
The Sigma $ ^{3} $ is always combined with the human interface software type HMI-207CE by the same
manufacturer that can be used on a remote computer and is intended for reading measurements, stored measurement data and for setting of parameters for the flow computer. This can act as an additional indicating device of the flow computer.
