CERTEON FM-PS2216 Inline Optical Flow Sensor User Manual

1. Product Overview

The CERTEON 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. Safety Information and Precautions

General Warnings

• WARNING! Improper installation may result in leakage, equipment malfunction, or electrical hazards.
• Disconnect power before installation, maintenance, or inspection.
• Do not use the product outside its specified electrical and environmental limits.
• This device is not a safety-critical measurement instrument and should not be used as the sole protective control in hazardous systems.
• Keep out of reach of children.

Usage 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 in the specifications. 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.

3. Setup and Installation

Preparation

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

Installation Steps

1. Install the sensor inline with the pipeline, ensuring the flow direction matches the indicated arrow on the sensor body if present.
2. Secure all connections to prevent leakage.
3. Connect the signal output wires to the control system according to the wiring configuration provided below.

4. Operating Instructions

Working Principle

The sensor operates using an internal impeller that rotates when liquid flows through it. This impeller interrupts an optical path, generating pulse signals. By measuring the impeller's rotation time or pulse frequency, the connected control system accurately determines the water flow rate. This design, free of magnets and based on optical induction, is ideal for continuous monitoring of drinking water and other clean liquids.

Data Reading

When liquid flows through the sensor, the internal impeller rotates and interrupts the optical path, generating pulse signals. The control system calculates the flow rate by measuring pulse frequency or rotation time. Calibration may be required within the host system to achieve accurate flow measurement.

5. Maintenance

Storage

• 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.

Cleaning

• Clean the external housing with a soft, dry cloth.
• Do not use aggressive solvents or abrasive cleaning agents.

Inspection

• Periodically inspect pipeline connections for leakage or mechanical stress.

6. Troubleshooting

If the sensor is not providing expected readings or appears to be malfunctioning, please check the following:

• Power Supply: Ensure the sensor is receiving the correct voltage and current as specified.
• Connections: Verify all wiring connections (VCC, SG_OUT, GND) are secure and correctly assigned.
• Flow Direction: Confirm that the liquid is flowing in the correct direction through the sensor (if an arrow is present).
• Pipeline Obstructions: Check the pipeline for any debris or blockages that might impede flow or impeller rotation.
• Liquid Compatibility: Ensure the liquid being measured is clean, non-corrosive, and within the specified temperature and pressure limits.

If issues persist after checking these points, please contact customer support for further assistance.

7. Specifications

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

8. User Tips

• Always ensure the flow sensor is installed in the correct orientation to match the liquid flow direction for accurate readings.
• Before final installation, perform a quick test with a small amount of liquid to confirm basic functionality and check for leaks.
• For precise flow measurement, calibrate your control system according to the sensor's pulse output characteristics.
