Additional notes
K-Factors (pulses per fluid volume)
| Range Code | Body Size | Flow Range (ml/min) | Pulses per Gallon | Pulses per Liter |
|---|---|---|---|---|
| 10 | S1 | 30-300 | 181,336 | 47,909 |
| 20 | S2 | 100-1000 | 81,509 | 21,535 |
| 30 | S3 | 200-2000 | 42,051 | 13,752 |
| 40 | S4 | 300-3000 | 25,153 | 6,646 |
| 50 | S5 | 500-5000 | 15,737 | 4,157 |
| 60 | S6 | 700-7000 | 9,375 | 2,477 |
- Rate scale factor = 60 / K; rate scale factor x Hz = flow rate in volume per minute
- Total scale factor = 1 / K; total scale factor x pulses = total volume
Sensor Wiring
| Wire | Function |
|---|---|
| Red | + 8 to 28 VDC (positive) |
| Bare | + 5 VDC (signal output) |
| Black | - (ground) |
Installation with Blue-White Metering Pumps
- Diaphragm pump: mount the sensor on the discharge (outlet) side of the pump head, directly on the head or anywhere along the discharge tubing
- Peristaltic pump: mount the sensor on the suction (inlet) side of the pump head
- If chemical fails to inject within the pump's shut-down time, the pump stops and an alarm relay closes for remote alarm indication or a back-up pump
Working Range with CHEM-FEED Pumps
| Sensor | Published Flow Range (ml/min) | Actual Working Range with CHEM-FEED Pump (ml/min) |
|---|---|---|
| FV-100 | 30-300 | 30-200 |
| FV-200 | 100-1000 | 50-900 |
| FV-300 | 200-2000 | 100-1800 |
| FV-400 | 300-3000 | 300-3000 |
| FV-500 | 500-5000 | 500-5000 |
| FV-600 | 700-7000 | 700-7000 |
- For low viscosity (water-like) fluids only; consult the factory for viscous fluids
- If pump output is below the sensor's minimum range, the sensor will not detect chemical and the pump will alarm
