Compact Energy Meter
The compact meter PolluCom E is used for measuring energy consumption in heating or cooling circuits. On account of its high-precision flow sensor the application range reaches from district heating transfer stations to consumption billing for individual apartments. Optionally our PolluCom E can also be supplied as combined heating / cooling meter. For this version the switchover point between heating and cooling energy metering is programmable, so that, even for already installed meters, corrections according to plant specifications are possible (e.g. for buildings with concrete core activation).
Regarding meter remote reading and data communication the following modules are available:
• M-Bus according to EN 1434-3 with unlimited number of readouts & play interface for radio reading systems
• Mini-Bus for „garden gate reading” or as plug & play interface for radio reading systems
• M-Bus according to EN 1434-3 or Mini-Bus with withtwo inputs for consumption meters with remote reading pulse output
• Integrated data logger
• Potential- and bounce-free remote reading pulses (1 kWh per pulse)
-
Approval in class 2 according to EN 1434, measuring range
-
Temperature range of the flow sensor from 5 to 90 °C, thus also ideal applicability for so-called „6/12 °C chilling systems”
-
Optionally available with removable integrator for narrow installation sites:
-
PolluCom E/S with ca. 0.3 m connection cable and PolluCom E/SL with ca.1.2 m connection cable
-
Fast updating of measuring values (2 seconds for temperatures, 4 seconds for heating output and flow rate)
-
Standard optical interface
-
Tariff function for differentiated consumption billing (e.g. in dependencyon heating output)
-
Password protected parameter selections right on the meter itself without additional peripheral equipment
-
Temperature sensors Pt 500 with overall length 45 mm / diameter 5.2 mm,also available in overall length 45 mm / diameter 5.0 mm as well as in type DS 27.5 according to EN 1434-2
