Georg Fischer 7000/7001 Data Sheet

Signet 7000/7001 Vortex Flow Sensors

Blind Transmitter or Frequency Sensor

End connectors not shown.

Description

Signet Vortex Flow Sensors provide
extremely accurate and reliable flow
measurement with no moving parts.
Constructed of durable PVC, these
sensors can accommodate applica­tions such as chemical delivery.

Each unit is injection-molded to
achieve a smooth surface finish for
cleanliness and better chemical
compatibility. This drastically reduc­es manufacturing inconsistencies
and in-service particulation associ­ated with machined surfaces. End
connectors simplify installation and
allow unparalleled configuration
versatility.

The sensors feature either frequency
output or fixed 4 to 20 mA current
output, and can be used with the
comprehensive offering of Signet
flow instruments to achieve en­hanced system functionality. Integral
transmitters with local displays and
many additional features are avail­able as accessories, or select from
a wider variety of panel-mount flow
instruments.
