A precision instrument for the measuring and
documentation of water flow in heating, cooling
and drinking water systems.
PFM-2000 is a meter for pressure and flow meas-
urements across, for example, balancing valves.
Valve characteristics for a number of valves from
different manufacturers are stored in the
PFM-2000's memory. The valve database is
updated continuously. Every instrument unit is
delivered with a CD-ROM containing demo
programs, valve data and manuals.
