Signet 2000 Micro Flow Sensor
*3-2000.090-1*
3-2000.090-1 Rev. 6 01/19
Description
The Signet 2000 Micro Flow Rotor Sensor is constructed of Polyphenylene Sulfi de (PPS)
which provides high material strength. The 2000 offers two fl ow ranges starting at 0.11 or
1.13 lpm (0.03 or 0.3 gpm), for clean process liquids, regardless of fl uid color or opacity.
This sensor can be connected to fl exible tubing or rigid pipe, and uses standard hardware
for mounting. Only one moving part and a low pressure drop across the sensor reduces
operating costs and maintenance requirements.
Features
• Operating range 0.11 to 12.11 lpm (0.03 to 3.2 U.S. gpm)
• Simple mounting
• ¼ in. NPT or ISO threads for simple pipe or tubing connection
• Measures opaque and transparent liquids
• Low pressure drop
• Standard cable 7.6 m (25 ft)

standards or other solutions) are warranted out of box but not
warranted against any damage, due to process or application
failures (e.g. high temperature,
mishandling (e.g. broken glass,
chemical poisoning, dry-out) or
damaged membrane, freezing
and/or extreme temperatures).
