Heard of the Kamstrup Heat Meters? What Does a Heat Meter Do? Each building and apartment connected to
a district heating system consume thermal energy to maintain an optimum temperature in premises. A device
that controls the amount of thermal energy consumed is called a heat meter. The heat meters can also control
the parameters of a heat sensor (water circulating in the heaters).
By using a heat meter such as the kamstrup heat meters, you only pay for the heat consumed. Therefore, if
you are implementing energy-saving measures in your building, such as thermal insulation of walls and floors,
replacing entrance doors or replacing windows on stairs, etc., you still need a heat meter to record the
decrease in the amount of heat consumed and reduce the heating bill accordingly. And these savings can
reach 40% of actual spending.
What is a kamstrup heat meter?
A kamstrup heat meter is a device to measure the thermal energy consumed or transmitted. It consists of a
flow meter, a temperature sensor, and output temperature sensors and an electronic calculator. Given the flow
and temperature data, the meter can calculate the amount of heat consumed by a building or apartment.
To measure the amount of heat the following formula is used: the heat consumed is equal to the amount of
heat supplied by the flow meter, multiplied by the temperature difference of the heat conveyed in the feed.
Mathematically a heat meter is: (heat consumed = heat supplied by a flow meter x Temperature difference of
the heat conveyed in the feed). The product of the return line and the thermal coefficient characteristics that
characterize the thermal parameters.
The current legislative and regulatory framework of the heat meter defines certain rules for its installation. For
instance, a temperature or heat meter must be included in a status register of measuring instruments, similar
to other measuring instruments.
Information on the inclusion of the Kamstrup Multical heat meter in the record of measuring instruments can be found on the internet. Also, the flow meter shall be installed in straight sections and temperature sensors shall
be installed in tubes with a diameter of at least 70 mm and shall include additional accessories such as filters,
ball valves, pressure gauges and thermometers. This set of equipment is called the commercial unit of
measurement of thermal energy.
