2. Safety Information
Please read and understand all instructions before installing or operating the flowmeter. Failure to follow these guidelines may result in damage to the device or injury.
- Pressure and Temperature Limits: Never exceed the specified pressure and temperature limits for this device. Refer to the Technical Specifications section for details.
- Medium Compatibility: Ensure the liquid medium being measured is compatible with the flowmeter's acrylic and metal components.
- Proper Installation: Install the flowmeter securely and according to the instructions to prevent leaks or disconnections.
- Handling: Handle the device with care to avoid physical damage to the transparent body or internal components.

3. Setup and Installation
The LZM-15T flowmeter is designed for panel mounting and easy integration into existing liquid systems.
- Prepare the Installation Site: Identify a suitable location for panel mounting, ensuring easy access for reading and maintenance.
- Connect Inlet/Outlet: The flowmeter features a 1/2in male thread for the inlet and a 1/4in female thread for the outlet. Connect your PVC pipes or other compatible plumbing using appropriate sealants (e.g., PTFE tape) to ensure a leak-free connection. Ensure the flow direction matches the arrow on the flowmeter body, if present.
- Secure Mounting: Secure the flowmeter to the panel using the designated mounting points. Ensure it is vertically aligned for accurate readings.
- System Flush (Optional but Recommended): Before final operation, it is advisable to flush the system to remove any debris that could affect flowmeter accuracy or cause damage.

4. Operation
Once installed, the flowmeter provides real-time flow rate readings for liquid mediums.
- Initiate Flow: Begin the flow of the liquid medium through the system.
- Read the Scale: The internal float will rise in proportion to the flow rate. Read the flow rate at the widest part of the float against the GPM (Gallons Per Minute) or LPM (Liters Per Minute) scale.
- Adjust Flow (if applicable): If your system allows, use the adjustable knob at the bottom of the flowmeter to fine-tune the flow rate as needed. Turning the knob clockwise typically restricts flow, while counter-clockwise increases it.
- Monitoring: Continuously monitor the flow rate to ensure it remains within desired parameters.

5. Maintenance
Regular maintenance ensures the longevity and accuracy of your flowmeter.
- Cleaning: Periodically inspect the transparent body for any buildup or discoloration. If necessary, disconnect the flowmeter from the system and gently clean the interior and exterior with a soft cloth and mild, non-abrasive cleaner. Avoid harsh chemicals that could damage the acrylic.
- Inspection: Check connections regularly for any signs of leaks or wear. Ensure the mounting remains secure.
- Storage: If storing the flowmeter for an extended period, ensure it is clean, dry, and stored in a cool, dry place away from direct sunlight and extreme temperatures.
6. Troubleshooting
This section addresses common issues you might encounter with your flowmeter.
| Problem | Possible Cause | Solution |
|---|---|---|
| No flow reading / Float stuck | No liquid flow; Debris inside; Incorrect installation (e.g., not vertical). | Verify liquid supply; Disconnect and clean the flowmeter; Reinstall correctly, ensuring vertical alignment. |
| Inaccurate readings | Air bubbles in the system; Debris affecting float movement; Incorrect calibration (unlikely for this model); Not installed vertically. | Bleed air from the system; Clean the flowmeter; Ensure vertical installation. |
| Leaks at connections | Improperly sealed threads; Damaged threads; Overtightened/undertightened connections. | Reapply thread sealant (e.g., PTFE tape); Inspect threads for damage; Adjust tightening torque. |
