Operating Instructions
Description
Features
The Signet 2000 Micro Flow Rotor Sensor is constructed of Polyphenylene Sulfide (PPS)
which provides high material strength. The 2000 offers two flow ranges starting at 0.11 or
1.13 lpm (0.03 or 0.3 gpm), for clean process liquids, regardless of fluid color or opacity.
This sensor can be connected to flexible 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.
• 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)
