Circular Gear Flow Meter
This positive-displacement circular gear flow meter measures liquid flow in pipelines, providing instantaneous and cumulative flow data with ±0.5% accuracy and flow ranges from 0.0028 L/min to 120 L/min by size. It offers pulse, 4–20 mA, and RS485 outputs, 24 V DC or 3.6 V battery power, and is suitable for industrial liquid metering requiring high repeatability across wide viscosity and temperature ranges.
- Accuracy
- ±0.5% of measured value (viscosity >20 cSt DN6; >30 cSt DN8–DN20); repeatability ±0.05% under identical operating conditions
- Temperature range
- -60℃ to 150℃
- Output signal
- Original pulse, equivalent pulse, 4–20 mA two-wire/three-wire (optional), RS485 (optional)
- Power supply
- 24 V DC or 3.6 V lithium battery (automatic switching); <1.5 mW
- Measures various fluids with different clearances, bearing types and materials
- Wide measurement range and multiple specifications for different applications
- Measurement unaffected by viscosity within specified range
- Low pressure drop, low noise
- High-sensitivity measurement with high precision and outstanding repeatability
- Output signal unaffected by temperature; high accuracy at low flow measurement range
