Pulse emission

Pulses are emitted at intervals of 1 second. The number of pulses to be emitted is calculated every second. Pulses
are emitted in bursts with a pulse duration of 2…5 ms and pauses depending on the current pulse frequency. The
duration of the pauses between the individual bursts is approx. 30 ms.

The transmitted pulse signal is the average determination of a series of flow measurements. This means that
during start-up there will be a transient phenomenon until correct flow signal has been obtained. Furthermore, this
brings about a pulse tail of up to 8 seconds in case of sudden hold.

Accuracy

ULTRAFLOW

®

54 and 34 have been developed as a volume flow sensor for use with energy meters according to

DS/EN 1434. Permitted tolerances in DS/EN 1434 for flow sensors with a dynamic range of 1:100 (q

i

:q

p

) are shown

in

Diagram 14

. The tolerances are defined for classes 2 and 3 with following formulas:

Class 2:

q

but max. 5 %

Class 3:

q

q

p

×

+

05

.

but max. 5 %

DS/EN 1434 defines following dynamic ranges (q

i

:q

p

): 1:10, 1:25, 1:50, 1:100 and 1:250.

In connection with accuracies the range from q

p

to q

s

is defined as max. flow short-term, where tolerances are

adhered to. There are no requirements as to the relationship between q

p

and q

s

. See

Table 1

for information on q

s

for ULTRAFLOW

®

.

To ensure that the sensors meet the tolerance requirements, DS/EN 1434-5 specifies calibration requirements in
connection with verification of sensors. The requirements for flow sensors are that they have to be tested at
following 3 points:

q

i

…1.1 x q

i

, 0.1 x q

p

..0.11 x q

p

and 0.9 x q

p

…q

p

During testing the water temperature must be 50 °C ±5 °C for ULTRAFLOW

®

as a heat meter.

For ULTRAFLOW

®

as a cooling meter the water temperature must be 15 °C ±5 °C

Further requirements are that the tolerance of the equipment used to perform the test must be less than 1/5 MPE
(Max. Permissible Error) in order for the acceptance limit to be equal to MPE. If the equipment does not meet this
standard, the acceptance limit must be reduced by the tolerance of the equipment.

ULTRAFLOW

®

will typically do better than half of the permitted tolerance according to DS/EN 1434 class 2.
