VF-2200
Vortex Flow Sensorfor water

OUTLINE
The VF-2200 Flow Sensor is an improved version of well-received
VF-2000 and has wider flow range than VF-2000. The VF-2200 FlowSensor offers a cost-effective instrument for the measurement ofliquid flow.
A simple and compact design makes the VF-2200 a good choice forthe measurement of water, pure water, cooling water.
Current output model, Pulse output model and Display model withcurrent / alarm outputs are available. Fitting is selectable from various types according to use.

FEATURES❏ Simple and Compact Design
The VF-2200 Flow Sensor is assembled with a few pieces ofcomponents. The sensor body and Shedder bar (vortex generator) 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 isdesigned to eliminate deposits.
❏ No Maintenance Cost
Since the VF-2200 has no moving parts, no maintenance isneeded.
❏ Low Pressure Loss
A combination of straight flow path and Shedder bar gives a lower
pressure loss compared with other types of flowmeters.
❏ Linear Output
Output signal is proportional to a volumetric flow rate.
❏ Display Model with Current and Alarm Output
3-digit LED display for flow rate, current output and alarm outputs(2-point) are provided in compact design.
❏ CE Marking
The VF-2200 meets the EC directive for CE mark.

OPERATING PRINCIPLE
A bluff body or Shedder bar in the flow generates a street of vortices
downstream. The VF-2200 Flow Sensor measures the flow rate bycounting the number of vortices with a piezoelectric sensor.
