SINGLE Flow Meters
DFM4 Series
SINGLE fl ow meters of the DFM4 series measure the fl ow
rate of temperature and cooling circuits. For applications
using water as a transfer medium, DFM4 monitors the fl ow
rate and measures medium temperatures up to 200 °C.
Used for applications with heat transfer oil, the fl ow meter
measures temperatures of up to 350 °C. The DFM4 fl ow
meter offers comprehensive process information as well
as monitoring and alarm functions.
In contrast to many conventional fl ow meters used for
temperature control applications, SINGLE DFM4 operates
without moving components and measures the fl ow rate
by means of the differential pressure across an orifi ce
plate. Hence, it is virtually maintenance-free and unaffected
by contamination.
The fl ow rate can be displayed in l/min or m³/h as required.
The temperature is displayed in °C. A variety of
different metering ranges are available for both water and
oil as transfer media. Each DFM4 fl ow meter is delivered
with technical documentation including CE mark and factory
certifi cation.
