The OV 16 flow meter is particularly suitable for measuring the flow rate of highly viscous fluids such as syrup, oil, or detergent concentrates.
The device contains two gear wheels driven directly by the fluid.
Every full revolution represents a fixed, known volume of liquid.
Each wheel has an embedded magnet that, when passing a Hall‑effect sensor, produces pulses whose count is proportional to the flow rate.
PRECAUTIONS
The Mini/Maxi flow ranges may vary depending on the viscosity, temperature, and pressure of the fluid.
Below is a reference with cola syrup:
| Cola syrup | - Viscosity 24 cSt at 20 °C - Pressure 5 bar - Min. 6 cm³/min - Linear output from 30 cm³/min - Max. 5,600 cm³/min |
The fluid must be free of solid particles that could interfere with the wheels.
| Flow range | 0.06...16 l/min (depending on viscosity) | |
| Accuracy | ± 1% (depending on viscosity) | |
| Repeatability | < ± 0.25 % | |
| Operating temperature | -10 ... +65 °C | |
| Pressure limit | 10 bar at 20 °C | |
| Mounting position | Horizontal (recommended) | |
| Couplings | Inner diameter: 7 mm | |
| Viscosity range | 5 ... 8,000 cSt |
Electrical characteristics:
| Power supply | 4.5...24 V DC (12 V DC recommended) | |
| Consumption | < 20.1 mA | |
| Output | NPN, open collector | |
| Signal voltage | 0 V GND | |
| Signal load | Max. 5 mA | |
| Leak current | Max. 10 μA | |
| Connector | 3-pin AMP 2.8 x 0.8 mm | |
| Signal | Square pulse | |
| Service cycle | Approximately 50% |
Materials:
| Housing | PEEK 150 GL 30 | |
