Many meters in Bulgaria are read manually at a visit by a reader, typically because the property has the first version of the electronic meters or evaporation meters (capillary meters).

Futura Heat can be read inside the flat by a service technician using a hand terminal. The terminal checks the entered data and informs the reader if an unusual reading occurs. The message is subsequently reviewed by the accounts personnel at Dalsia before the consumption accounts are prepared.

An evaporation meter has two ampoules with differently coloured liquids. The left ampoule shows last year’s consumption and the right the current year’s. Dalsia`s service technician reads two figures on the meter scale:

• This year’s consumption, which is used for the consumption accounts (right side).
• Last year’s consumption, which is used as control figure (left side).

Both figures are entered into a hand terminal, which immediately checks the entered data.
