Description
The GE552 volumetric single jet energy meter is characterised by its consistent
accuracy over time and its remarkable operating safety; high precision
measuring capability means that this device can be used across a wide range
of applications. The meter is available in 3/4” versions (nominal flow rate of
0,6 or 1,5 m³/h) and 1” versions (nominal flow rate of 2,5 m³/h). It is equipped
with a double register, and can therefore measure the thermal energy of both
heating and cooling operations. The temperature range of the meter makes
it ideal for metering energy consumption in residential buildings equipped
with a centralised heating/conditioning system and zone distribution.

Main characteristics
Its particularly compact structure makes it suitable for any type of installation.
The electronic part can be separated to allow installation in even the smallest
metering cabinets. Easy to use, by means of one single key. The display is
easy to read, and shows all the most important operating conditions. Its
reliability and notable measuring performance ensure excellent measuring
results throughout its working life. Thanks to the use of the most advanced
electronics (free of electromagnetic interference), it satisfies all the current
requisites in terms of measuring techniques for compact meters.
