VORTEX FLOWMETER (DELTA FLOWPET)
DATA SHEET
FMR, M
This instrument is a Karman vortex flowmeter capable of
measuring the flow rate of liquid, gas, and vapor. The heavy-
duty detecting section made of stainless steel ensures high
accuracy of the instrument.
FEATURES
1. The total flow and instantaneous flow rate can exter-
nally be selected and monitored.
2. The standard is a rainproof type that can be used out-
doors.
3. Heavy-duty stainless steel main body having the struc-
ture without moving part ensures high durability
4. It does not impose limitations to its mounting positions.
5. Remotely controllable external output (total pulse or
instantaneous analog) is available.

Within ±1% of full scale (or, for nominal diameter 10 mm, within ±2% of full scale).^(Note)
For liquid: FS = 8 m/s. For gas with nominal diameter 10 to 50 mm: FS = 30 m/s.
For gas with nominal diameter 80, 100 mm: FS = 50 m/s.
