Set pulse valence
To the pulses of UMG 505, energy can be assigned.
The energy per pulse is called pulse valence Iw in
Wh/pulse.
Iw = energy/pulse
The pulse valence may not be confused with the
meter constant. The meter constant is given in rota-
tion per kWh.
The correlation between pulse valence and meter
constant is:
Meter constant = 1/pulse valence
Pulse valence = 1/meter constant

Example 1.: The pulse frequency for a total power
of 500kW should be calculated, when the pulse
valence should be 250Wh/pulse.
Ptot [kW]
Pulse-Freq. [Hz] = ----------------------------------
Pulse valence [Wh] • 3,6
500 kW
Pulse-Freq. = ------------------- = 0,55 Hz
250 Wh • 3,6
Example 2.: The pulse valence for a total power of
100kW should be calculated, if the pulse frequency
should be 2Hz.
Ptot [kW]
Pulse valence [Wh] = -----------------------------
Pulse-Freq. [Hz] • 3,6
100 kW
Pulse valence = -------------- = 13,88 Wh
2 Hz • 3,6
