Heat Meter
Electronic, battery-supplied meters for determining the heat consumption in
autonomous heating and service water systems.
Saving and displaying of cumulative values on a selectable due date. Available
as compact single-jet meter with nominal flow of 0.6 m
The electronic Siemeca
IrDa interface.
The heat meter is used for measuring heat energy. The major areas of application are
heating systems with central heating facilities in which the heating energy is supplied to
several consumers as required.
This is useful in:
• Apartment buildings
• Offices and administration buildings
Typical users are:
• Private building owners
• Residential building cooperatives
• Facility management providers
• Real estate management
