11.2 Power Supplies
The Supercal 5 is always supplied with a battery and can also be supplied with mains power
supply module. These can be modified and retrofitted at any time.

11.2.3 Estimating the Battery Life of an M-Bus Application
The battery life of Supercal 5 doesn’t depend on any of these parameters:

Number of M-Bus devices attached to the M-Bus network

Network specifications, communication speed

Ambient temperature (5 °C–55 °C)
11.3 Measurement concept

The Supercal 5 measurement calculation is based on volume calculation. The number of
electrical pulses determines the volume directly.

Once the volume is determined, the flow rate is calculated according to this volume, and
the time taken for the pulses to occur.

The heat transfer is calculated from flow rate and the difference between “high temper -
ature” and “low temperature”.

The heat capacity and density of the heat transfer medium are included in the calcula-
tion.
