• Industrial Lubrication: Monitoring the flow of lubricating oils in heavy machinery to prevent catastrophic mechanical failures.

Unlock New Capabilities (Project Evolution)

• Durability Upgrade: Replace standard impeller-based water sensors with this OF05ZAT to prevent sensor failure when measuring thicker or harsher fluids like oil and diesel.

• System Integration: Pair this sensor's pulse output with an intelligent digital counting meter (like the CY7 series) to create automated shut-off systems when a precise volume of liquid is dispensed.

Package Includes: 

• 1 x OF05ZAT Liquid Flow Sensor (G1/2 DN15)

FREQUENTLY ASKED QUESTIONS (FAQ)

1. What liquids is this sensor designed for? It is specially designed to handle milk, gasoline, oil, and diesel, alongside standard water.

2. What size are the threaded ports? It features standard G1/2" (DN15) male threads on both ends.

3. How do I know which way the fluid should flow? There is a prominent arrow printed on the red label indicating the correct flow direction.

4. What kind of output signal does it provide? It provides a digital pulse output (typically via a Hall effect sensor) proportional to the fluid flow.

5. What do the wire colours mean? Typically, Red is VCC (Power), Black is GND (Ground), and Yellow is the Signal Output.

6. Where is this sensor manufactured? It is an authentic AICHI product, made in Japan.

7. What are the dimensions of the main body? The main black housing measures 46mm x 37mm x 47mm.

8. Can I use this with an Arduino? Yes, the pulse output can be easily read by an Arduino using an interrupt pin.

9. Do I need a pull-up resistor? Depending on your microcontroller, you may need a 10k pull-up resistor on the signal wire if the board doesn't have internal pull-ups.

10. Is it food-grade safe? It is widely used for milk measurement; however, ensure you follow proper sanitation protocols for your specific food-grade application.

11. Can it handle highly corrosive acids? No, it is designed for fuels, oils, and dairy. Strong acids may degrade the internal components.

12. How do I calculate the volume? You must multiply the number of pulses received by the specific "K-factor" (pulses per litre) provided in the sensor's datasheet.

13. Is the sensor waterproof? The internal fluid pathway is sealed, but the external electrical connector and wiring should be protected from direct water exposure.

14. What does DN15 mean? DN15 is a nominal pipe size designation, roughly equivalent to a 1/2-inch inner diameter.

15. Can I mount it vertically? Yes, but ensure the fluid flows upwards to prevent trapped air bubbles from causing inaccurate readings.

16. Why use this over a cheap plastic water flow sensor? Standard water sensors will quickly seize or degrade when exposed to the viscosity of oils or the harshness of gasoline.

17. What is the maximum operating pressure? Please consult the official Aichi datasheet for exact pressure limits, but it is built for standard industrial pumping pressures.

18. Does it include a digital screen? No, this is a raw sensor that requires an external microcontroller or counting meter to display the data.

19. What type of mechanism is inside? Sensors rated for oils and viscous fluids often use oval gear or specialised positive displacement rotors rather than simple impellers.

20. Is the white cable protected? The cable features a thick white outer jacket to protect the internal wires from industrial wear and tear.
