Georg Fischer Signet 2000 User manual

Signet 2000 Micro Flow Sensor
Technical Notes:
• Horizontal surface mount (±30°) recommended for
optimum performance.
• Suitable for clean fluids only. Suspended solids will cause
mechanical failure.
• 1/4 in. NPT or ISO 7/1 - R1/4 (male) port connections
• NEMA 4X/IP65 splashproof enclosure
2. Recommended Sensor Position
1. Compatible Instrument Wiring
Technical Notes:
• Use 2-conductor twisted-pair shielded cable for sensor cable splices up to 300 m (1000 ft) max.
• Maintain cable shield through cable splice.
• Route sensor cable away from AC power lines.
• AUX power required when used with any Signet 8550 Process Pro Flow Transmitter.

5. Calibration
The K-Factors listed below represent the number of pulses the sensor will generate for each engineering unit of fluid which passes.
They are listed in U.S. gallons, liters and ml by sensor model:
Conversion Formulas:
1 U.S. gallon =
0.83267 Imperial gallon
Technical Notes:
• Compatible fittings (customer supplied): Female union (shown), reducer, or hose barb type.
• Always apply thread sealant to sensor port threads to prevent leakage.
