E1
and
E3
MULTICAL
603
calculates
energy
on
the
basis
of
the
formula
stated
in
EN
1434
‐
1,
which
uses
the
international
temperature
scale
issued
in
1990
(ITS
‐
90)
and
the
pressure
definition
of
16
bar.
In
a
simplified
form
the
energy
calculation
can
be
expressed
as:
Energy
=
V
x
x
k.
The
calculator
always
calculates
energy
in
Wh
,
and
then
converts
the
value
to
the
selected
measuring
unit.
E
Wh
=
V
x
x
k
x
1000
E
kWh
=
E
Wh
/
1,000
E
MWh
=
E
Wh
/
1,000,000
E
GJ
=
E
Wh
/
277,800
V
is
the
added
(or
simulated)
water
volume
in
m
3
is
the
measured
temperature
difference:
Heat
energy
(E1)
=
inlet
temperature
less
outlet
temperature
Cooling
energy
(E3)
=
outlet
temperature
less
inlet
temperature
Both
in
the
display
and
during
data
reading
each
energy
type
is
uniquely
defined,
e.g.
Heat
energy:
E1
=
V1(t1
‐
t2)k
Cooling
energy:
E3
=
V1(t2
‐
t1)k
k
is
the
heat
coefficient
of
water,
calculated
according
to
the
formula
of
EN
1434
and
OIML
R75
‐
1:2002.
