Flow Control
FlowControl is the solution for reliable, fully automatic flow measurement of release agent and air for Wollin spray machines.
ESM: Flow Sensor Flow Control for Air & Release Agent (Optional)
On the new ESM machines, the flow sensor is installed directly on the machine horizontal unit (optional).
Flow measurement of the release agent quantity
- Automatic flow measurement per cycle
- Target / actual comparison of flow rate values
- Message in case of deviation above the permissible value
- Signal cycle stop in case of deviation
- Visualization of process data with storage for quality statistics
- Non-contact flow sensors (magnetic inductive)
Total air flow measurement (all spray circuits)
Compressed air consumption monitoring for total volume used per cycle. Process values are shown on the display of the flow sensor and on the PC3 control.
| Measuring range | 3...700 m3/h |
| Accuracy (within measuring range) | ± (3 % MW + 0,3 % MEW) |
| Repeatability [% of measured value] | ± 1,5 % MEW |
| Compressive strength | 16 bar |
Flow measurement of release agent per spray circuit
Each spray circuit can be measured individually.
| Measuring range | 0,1...25 l/min |
| Accuracy (within measuring range) | ±(0,8 % MW + 0,5 % MEW) |
| Repeatability [% of measured value] | ± 0,2% MEW |
| Compressive strength | 16 bar |
Flow measurement per spray circuit for machines with PC3 control system
- 4/6/8 circuits
- Minimum and maximum quantity in liters can be defined for each circuit
Stand-alone device with flow measurement
up to 5 sensors with control S7
- 1-4 sensors for release agent 1 sensor for concentrate
- Serves for measuring point monitoring
- Minimum and maximum limits are adjustable
- Display of the flow rate
- 2000 values can be stored per channel
- Non-contact flow sensors (magnetic inductive)
- Visualization of process data with storage for quality statistics
- für Qualitätsstatistik
- Optional:
- Flow meter with reducer
- With pressure switch for display of actual pressure
Concentrate flow measurement
We use a flow meter that determines the flow volume of liquids.
- Non-contact measurement
- Measurement of conductive and non-conductive liquids
- IP65, fully potted
| Measuring range | 8-3000 ml/min |
| Accuracy (within measuring range) | ≤ ± 1% MW +- 0,15% MEW |
| Repeatability [% of measured value] | ≤ 0,5% MW |
| Compressive strength | 7 bar |
