Function
CONTECA
EASY ULTRA is an ultrasonic heat meter, especially
®
suited to measuring thermal energy consumption in residential
buildings; thanks to a double memory register, it can also meter
energy in both heating and cooling modes (option code 755810).
The device comprises an electronic calculator unit, an ultrasonic
flow meter and two temperature probes. The CONTECA
ULTRA meter is extremely simple to install and requires no special
maintenance.
The flow is measured using the two-way ultrasound technique, based
on the transit time method. As it has no moving parts, the device
is therefore not very susceptible to build-up issues and offers an
extremely low pressure drop.
The CONTECA
EASY ULTRA meter is equipped with an 8-digit LCD
®
display that can be switched on with a key. This display enables easy
reading of both energy consumption values and technical data, for
appliance operating status evaluation and data logging.
The CONTECA
EASY ULTRA meter is able to acquire up to 4
®
additional pulse inputs and two additional alarm-status digital inputs,
and is equipped for centralised teletransmission (max. 250 users) in
M-Bus protocol, on the RS-485 network. The device also supports
MODBUS RTU protocol.
