CERTEON FM-PS2216 Inline Optical Flow Sensor User Manual

1. Product Overview

The FM-PS2216 is a compact inline optical flow sensor designed to detect and monitor liquid flow in low-flow pipeline systems. It operates using a photoelectric sensing principle and generates pulse signals proportional to the flow rate. The magnet-free design ensures improved hygiene, reduced contamination risk, and long-term operational reliability.

This sensor is suitable for integration into coffee machines, aroma machines, water dispensers, water heaters, and similar low-flow liquid control systems.

2. Specifications

Note: Electrical parameters such as operating voltage, current consumption, and maximum pressure rating must be confirmed by the seller before installation.

3. Installation and Setup

3.1. Preparation

• Ensure the pipeline is clean and free of debris before installation.
• Confirm that the liquid medium is compatible with plastic materials.
• Verify the correct power supply specifications before electrical connection.

3.2. Installation Steps

1. Install the sensor inline with the pipeline.
2. Ensure the flow direction matches any indicated arrow on the sensor body.
3. Secure all connections to prevent leakage.
4. Connect the signal output wires to the control system according to the wiring configuration provided by the seller.

4. Operating Instructions

4.1. Data Reading

When liquid flows through the sensor, the internal impeller rotates and interrupts the optical path, generating pulse signals. The connected control system calculates the flow rate by measuring the pulse frequency or rotation time.

Calibration may be required within the host system to achieve accurate flow measurement.

5. Maintenance

• Store the product in a dry and ventilated environment. Avoid direct sunlight and high humidity conditions.
• If not used for an extended period, ensure the sensor is drained of liquid and dried internally.
• Clean the external housing with a soft, dry cloth. Do not use aggressive solvents or abrasive cleaning agents.
• Periodically inspect pipeline connections for leakage or mechanical stress.

6. Troubleshooting

This section addresses common issues and preventative measures.

6.1. General Precautions

• This product is intended for clean water or similar non-corrosive liquids only. Do not use with flammable, explosive, or highly viscous liquids.
• Ensure the operating pressure and temperature remain within limits specified by the seller. Excessive pressure may damage the internal impeller or housing.
• Do not disassemble the sensor housing. Internal components are factory-calibrated and not user-serviceable.
• Avoid mechanical shock or dropping the device during installation.
• Ensure proper electrical insulation and stable power supply to prevent signal interference.
• Keep away from strong electromagnetic interference sources.
