SCYLAR INT M

SCYLAR INT M

CALCULATOR

Application

The calculator SCYLAR INT M is a two-channel calculator for measuring thermal energy in heating and cooling circuits. It includes the functions of two calculators. 2 independent energy measurements can be made in one housing at the same time. It is highly suitable in an industrial surrounding. Billing-relevant data can be calculated in the range of local heating and district heating with very high precision. Due to its variety of additional functions it is also very well prepared for future requirements.

  • Verification change

    In case the calculator needs to be exchanged (e.g. after the end of the verification period)
    this can easily be done with just a few simple steps.

    .) The simple disconnection via the plug system,
    .) Removeable connecting plate,
    .) Top-hat rail fixing of the housing,
    .) or simple separation of the upper part form the lower part

    enables a simple and fast exchange of the calculator.
