• 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)
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.
Applications
• Coolant Flow
• Dosing
• Batch Dispensing
• Not recommended for Strong Oxidizers

Operating Temperature/Pressure Graphs
Note:
The pressure/temperature graphs are specifically for the Signet sensor. During system design the specifications
of all components must be considered. In the case of a metal piping system, a plastic sensor will reduce the
system specification.
