Typical system giving the heat flow in W,kW, MW or BTU
All sensors are clamped external to the piping During
measuring

These systems are ideal
for energy efficiency optimization in industrial sectors
and buildings. EESIFLO™ offers a highly accurate,
low cost and robust Energy Management Solution.
The BTU (or Energy) Flow measurement systems can be
readily configured for almost any size of pipe and are
completely non-intrusive, since all the sensors are
installed on the outside of the pipes being measured.
Advantages over traditional type flowmeters are seen
by the accuracy ,sensitivity and longevity of the meters
since they are able to measure both high and low flow
rates with the same accuracy, due to the fact that the
transit time technology is not dependant on moving parts
and frictional wear and tear.

Using two additional clamp on temperature sensors (PT100) or
customer temperature inputs , we are ready to establish the
quantity of heat by a method known as the Differential Measurement
Priniciple.
Our systems can calculate the heat flow by taking into account
the temperature difference between the inlet and outlet ,the
flow at the outlet of the system in conjunction with some
other relevant properties of the medium (density and specific
heat capacity).
The co-efficents, which the instrument needs to know, in
order to measure the heat flow of various media are pre programmed
into the flowmeter.In cases where the temperatures of inflow
and/or outflow are known , or are constant during the whole
measuring period, you may enter these fixed temperatures manually
into the instrument.
In these instances, the temperature sensors need not be connected.

the following information is available:
- Volume flow
- Heat flow
- Flow velocity
- Total flow volume or heat quantity (if total counting
activated)
- Temperature T1 (inlet temperature)
- Temperature T2 (outlet temperature)
- Temperature difference T1-T2
EESIFLO™ heat meters give the option of displaying
two of these measured values (one in each line of the
display) and of configuring the display readings according
to your requirements |
