Heat Cost Allocators

QUNDIS - Heat Cost Allocator

QUNDIS is the market leader in the field of heat cost allocators. At our plant in Erfurt more than 4 million devices are produced and sold on the world market every year. Our speciality: metering accuracy. While heat cost allocators based on the evaporation principle have a measurement tolerance of up to 15 percent, the Q caloric technology (2-sensor models) ensures a maximum deviation of 2 percent.

Heat Meters

QUNDIS - Radio Integrated Heat Meter

Radio-integrated for even more convenience. The new, Q heat 5.5 R compact heat meter with integrated radio technology stands out in terms of its flexibility for future-proof use in apartment buildings as well as commercial premises.

QUNDIS - Radio Integrated Ultrasonic Heat Meter

Metering accuracy meets future-proof features. Ultrasonic metering technology stands for precision, long-term stable readings and easy handling during installation. If this is combined with integrated radio technology, it becomes a highly convenient package in the field of consumption data acquisition. The short, static metering cycle of every 12 seconds with the 10-year battery (optional every 4 seconds with the 7-year battery), the dynamic range of up to 1:250 as well as the Class 2 metering accuracy all result in a very high level of reading precision.

QUNDIS - Electronic Heat Meter

Compact and versatile. The Q heat 5 / Q heat 5.5 electronic heat meter is fitted with an IrDA interface as standard. It is available as a screw-type version and a measuring capsule version for the connection interfaces IST (G2″ – Ista), A1 (M77 x 1,5 – Allmess) and TE1 (M62 x 2 – Techem). If data transmission is to be implemented by radio (Q AMR, Q walk-by) or by cable (Q M-Bus), the device can simply be retrofitted with an add-on module.

QUNDIS - Heat Meter

Perfect integration into M-Bus networks. QUNDIS offers two new versions of its tried-and-tested Q heat 5 screw-type heat meter. The Q heat 5 M-Bus / Impulse-IN has integrated M-Bus and Impulse-IN communications interfaces. This enables up to 2 water meters to be integrated into an existing M-Bus network via a standard load. Thanks to the unique operating concept, parameterising the heat meters is child’s play. This significantly reduces the installation work and the cost of integration into an M-Bus network. The Q heat 5 M-Bus does without the Impuls-IN interface. Because of their compact design and removable calculator unit, the heat meters are ideal for installation situations where space is limited. In its class, at only 63.6 mm the Q heat 5 M-Bus / Impulse-IN heat meter features the smallest installation height on the market.
