QALCOSONIC E3 is designed for commercial accounting of heating and cooling energy when heating media is water and is used in centrally heated objects: residential houses or heat supply objects.
Integrated into the front panel of calculator. It is designed
for data reading via M-bus protocol and parameterization
of the meter.
The internal radio provides data reading via WMBUS telegram:
S1, T1 OMS mode, LoRa
WMBUS telegram:
Time of storage of all measured integral data, also without power supply to the electronic unit: at least 15 years

| Nominal pressure [bar] | PN16/25 bar | |
| Pressure loss | 0,63 / (0,25) bar | |
| Battery lifetime | 15+1 years | |
| Flow sensor cable length | 1,2 m (2,5 m or 5 m – special order) | |
| Temperature sensor Pt500, two-wire connection, cable length | Up to 10 m | |
| Temperature measurement range | 0°C – 90°C, 0 0C – 130°C | |
| Mounting of calculator | Mounting on standard DIN-rail or on the wall | |
| Number of configurable pulse inputs/ outputs | 2 or no (to be specified when ordering), OB – in the operating mode; OD – in the test mode |
When the output is configured for energy, the value of its pulses can be selected from the list (depending on the rated flow qp and energy measurement units):
| Energy pulse value, when units are “kWh” or “MWh” | 0,00001 - 10 000 MWh/pulse |
| Energy pulse value, when units are “GJ” | 0,0001 - 10 000 GJ/pulse |
| Energy pulse value, when units are “Gcal” | 0,0001 - 1 000 Gcal/pulse |
| Water volume pulse value, m3/pulse | 0,001 - 10 m3/pulse |
f the meter is ordered with the pulse input-output device, then a permanently connected 1.5 m length cable is fitted in the
meter for connecting the inputs-outputs:
| Permanent flow rate qp, m3/h | Upper flow-rate qs, m3/h | Lower flow-rate qi, m3/h | Threshold value of flow rate, m3/h | Length of the flow sensor L, mm | Pressure losses at qp, kPa | Joining to the pipeline (Thread – G, flange – DN) |
