Cost-effective instrument

VF-2000

Vortex Flow Sensor

The VF-2000 Flow Sensor offers a cost-effective instrument for the

measurement of liquid flow.

A simple and compact design makes the VF-2000 a good choice for

the measurement of water, pure water, cooling water.

Current output model, Pulse output model and Display model with

current / alarm outputs are available.

Features

❏ Simple and Compact Design

The VF-2000 Flow Sensor is assembled with a few pieces of

components. The sensor body and Shedder bar (vortex genera-

tor) are molded as one component. This design approach has

reduced the cost as well as the size and weight of the flowmeter.

Sensor body is made of PPS (Polyphenylene sulfide) and is de-

signed to eliminate deposits.

❑ No Maintenance Cost

Since the VF-2000 has no moving parts, no maintenance is

needed.

❑ Low Pressure Loss

A combination of straight flow path and Shedder bar gives a

lower pressure loss compared with other types of flowmeters.

❑ Display Model with Current and Alarm Output

3-digit LED display for flow rate, current output and alarm out-

puts (2-point) are provided in compact design.

❑ CE Marking

The VF-2000 meets the EC directive for CE mark.

Operating Principle

A bluff body or Shedder bar in the flow generates a street of vorti-

ces downstream. The VF-2000 Flow Sensor measures the flow rate

by counting the number of vortices with a piezoelectric sensor.
