Features
OF-Z flow sensor is suitable for measuring oil (heavy oil, light oil, heating oil, etc.). It is a flow sensor with elliptic gears that measures microflow with accuracy.
- Measures heavy, light, heating oil, etc.
- Measures the microflow range with superior manufacturing technology.
- Good at measuring pulsating flow.
- Amplifier's built-in magnetic sensor, which is strong against noise, is output in proportion to the flow velocity.
- Pulse output by open collectors or voltage pulse.
- Measures a wide range of flow rates with high accuracy.
- Simple structure due to the elliptic gears employed as a measuring principle.
- Capable of measuring various liquids.
- RoHS compliant (Complies with the RoHS directive to address the environmental issues.)
Flow Rate
The flow rate for the OF05ZAT Oval Gear Flow Meter Sensor depends directly on the viscosity of the liquid you are measuring. Because it utilizes high-precision elliptical/oval gears, higher-density or higher-viscosity liquids actually allow the sensor to capture micro-flows more accurately by reducing fluid slippage past the gears.
Depending on your specific version or fluid choice, the rated flow ranges break down as follows:
1. General Flow Range
- Standard Operating Range: 1 to 10 Liters/minute (L/min), which translates to roughly 60 to 600 Liters/hour (L/H).
- Low-End Start-Up Range: For highly viscous fluids like heavy oils or honey, it can accurately monitor micro-flows as low as 0.5 to 5 Liters/hour (L/H).
2. Flow Rate by Fluid Viscosity
According to the original manufacturer technical specifications (Aichi Tokei), the official precision guaranteed ranges are:
| Fluid Example / Viscosity | Flow Rate Range |
| High Viscosity (5.0 to 200 mPa·s) — Heavy oil, Honey, Syrups | 0.0085 to 0.85 L/min (approx. 0.5 to 50 L/H) |
| Medium Viscosity (2.0 to 5.0 mPa·s) — Diesel oil, Light oil | 0.017 to 0.85 L/min (approx. 1 to 50 L/H) |
| Low Viscosity (0.8 to 2.0 mPa·s) — Water, Kerosene, Milk | 0.05 to 0.85 L/min (approx. 3 to 50 L/H) |
(Note: Certain aftermarket variants optimized with a larger G1/2" internal clearance can handle broader generic ranges up to 5–300 L/H or 30–300 L/H depending on the specific model's internal cavity calibration.)
3. Pulse Calibration (For Programming)
If you are hooking this up to a microcontroller (like an Arduino, ESP32, or PLC) to calculate live flow rates, use these parameters:
- Pulse Constant: 0.46 mL per Pulse (0.46mL/P)
- Output Formula: 1 Liter of fluid yields approximately 2,174 pulses.
- To calculate the instant flow rate, you can use:
Flow Rate (mL/min) = Pulses per minute x 0.46 - Maximum Output Frequency: ~30 Hz to 31 Hz (at maximum guaranteed flow).
For many flow meters, the flow rate \( Q \) can be calculated using the following equation:
