VORTEX FLOWMETER (DELTA FLOWPET)

EDS6-122a

Aug. 10, 2005

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.
