Heat Quantity Measurememt in any Environment
The FLUXUS F704 Thermal Energy is specially designed for heat and cold quantity metering within industrial environments and is thus also available as hazardous area approved variants (ATEX, IECEx Zone 2).
Descripción.
Like all measuring systems of the FLUXUS series, the F704 Thermal Energy measures the volumetric flow rate
non-invasively via its clamp-on ultrasonic transducers. Simultaneously, temperature probes monitor the
temperatures at the supply and return lines of the heating or cooling system - either non-invasively with clamp-on
technology or by use of wetted temperature probes.
From the temperature difference as well as the measured volume flow rate and on the basis of the physical media parameters stored in the internal database
of the transmitter, the heating or cooling performance is calculated. With the help of the built-in totalizer function the FLUXUS F704 Thermal Energy can
also be used as an energy meter.
Further, the FLUXUS F704 Thermal Energy can also be equipped with two measurement channels to:
- allow for a complete energetic monitoring of a heat exchanger,
- to simultaneously measures at two heat- or cold carrying lines or
- to allow accurate measurements even at strongly disturbed flow profiles by compensating these.
Another important advantage of FLUXUS F704 Thermal Energy lies within its high zero point stability and unrivalled
accuracy even at very low flow rates - signal drift and significant measurement uncertainty, as it can often be observed at
magnetive-inductive heat quantity meters when measuring at low flow rates, can be ruled out. Moreover, even potential mineral deposits
on the inner pipe wall cannot influence the measurement.
The range of applications of the F704 Thermal Energy is almost unlimited, not only in terms of pipe dimensions (from 6 mm up to
12.000 mm), pipe materials and their manufactured quality (e.g. badly manufactured GRP pipes or rusty steel pipes) and temperatures
(from -190 ° C up to + 650 ° C) but also in terms of flowing media - from process and cooling water, to thermal oils or cryogenic media.
Both the ultrasonic transducers and temperature probes are carefully paired and matched by FLEXIM.
Due to these processes, the system measures with a high degree of accuracy and repeatability - even in applications
with only small temperature differences, such as in cooling water circuits. The clamp-on ultrasonic sensors are well
protected in extremely robust stainless steel mounting fixtures and withstand even the harshest mechanical stresses.
Thus, the FLUXUS F704 Thermal Energy offers the best metrological basis in terms of precision, long-life time, maintenance-free as well as
cost-effective monitoring of thermal energy flows within industrial environments and thus forms the foundation for further process optimization
tasks within the scope of a holistic energy management system - e.g. according to DIN ISO 50001.
Ventajas:
