Pulse-pause ratio
The pulse duration and the pulse value can be calculated with following MIN/MAX-Formula:
Calculating the min. "pulse value" or the max. "pulse duration":
IMPW_MIN = NORMV_MAX [m³/h] * IMPL [s] / 1200
IMPL_MAX = IMPW [m³] * 1200 / NORMV_MAX [m³/h]

The totalized consumption is stored every minute and is retained even if the supply voltage is
interrupted.
The totalized consumption can be shown on the display. A reset of the consumption meter can be
performed via the display menu or the EE-PCS Product Configurator Software.

Digital Interface
The EE741 is available in three different digital interface versions, with Modbus RTU, M-Bus
or IO-Link interface. The Modbus RTU and M-Bus interface parameters can be accessed and
changed with the help of the EE-PCS Product Configurator Software.
