FAUN — calculator (heat calculator) for compact heat and cold meters for metering stations, Qp 0.6–3 000 m³/h
Country: Poland · Model: FAUN
FAUN is a calculator for compact heat and cold meters that works with flow meters of nominal flow from 0.6 to 3 000 m³/h. Depending on the setting, it meters heat, cold, or both in one circuit. It is installed in heating substations, heating network metering stations, and residential, public and industrial buildings.

Description
The calculator works with ultrasonic and mechanical flow transducers and with matched Pt500 or Pt100 temperature sensors in a 2- or 4-wire connection, including those of other manufacturers. The temperature range is 1–180 °C, the temperature difference 3–175 K, the error limit Ec = ±(0.5 + ΔΘmin/ΔΘ) %. Energy is shown in GJ, MWh, kWh or Gcal, and volume in m³ on a large eight-digit display. The archive holds more than 5 000 registers, with two independent tariff registers, leak monitoring with two flow meters, and four pulse inputs for water, electricity or gas meters. Supply is from a 3.6 V lithium battery (AA, 2×AA, C or D, 6–12 years) or from 230 V AC or 24 V AC/DC mains. Two communication modules are installed without breaking the verification seals, including M-Bus, RS232, RS485, pulse outputs, analog outputs 4–20 mA or 1–10 V, LonWorks, Wireless M-Bus and IMR. The environment class is EN 1434 C, MID E1/M1, ambient temperature 5–55 °C, protection rating IP54, IP65 or IP68.
How to choose
The mode is set in the configuration: heat only, cold only, or both in one circuit. Switching to cold occurs when the supply temperature is lower than the return temperature and the set threshold. Communication modules are selected for the data collection system, and the M-Bus, Modbus, Lumbus and LonWorks protocols are supported. For mains supply take 230 V AC or 24 V AC/DC, and where there is no mains, the battery.

FAQ
Which flow meters does the FAUN calculator work with?
With ultrasonic and mechanical transducers of nominal flow from 0.6 to 3 000 m³/h, including those of other manufacturers.
Which temperature sensors connect to FAUN?
Matched Pt500 or Pt100 in a 2- or 4-wire connection.
Can FAUN meter cold?
Yes, it works as a heat meter, a cold meter or a combined one in one circuit. Switching to cold happens when the supply temperature is lower than the return temperature and the threshold.
How long does the FAUN battery last?
The 3.6 V lithium battery (AA, 2×AA, C or D) is rated for 6–12 years of operation. Supply of 230 V AC and 24 V AC/DC is also available.
Which interfaces can be installed in FAUN?
Two independent modules without breaking the verification seals, including M-Bus, RS232, RS485, pulse and analog outputs, LonWorks and Wireless M-Bus.
