Meter Installation
Install the water meter in the pipeline using the correct orientation, flow direction, and valve arrangement. Proper mechanical installation is required for reliable metering performance and leak-free operation.
Steps
- Install the water meter in a horizontal position with the register facing upward.
- Ensure the flow direction arrow on the meter body matches the direction of water flow.
- Install an upstream isolation valve to allow maintenance and meter replacement.
- A downstream isolation valve is recommended for easier servicing and leak testing.
- Use correctly sized gaskets and couplings to ensure a leak-tight installation.
- Install the meter in an accessible location for reading, inspection, and maintenance.
- Tighten connections only as required to achieve a proper seal — do not over-tighten.
- Do not use pipe sealant, thread compound, or PTFE / Teflon tape on meter threads.
Commissioning & Final Inspection
After installation, commission the meter carefully to verify proper operation, remove trapped air, and confirm that the register is recording flow correctly.
Steps
- Thoroughly flush the service line before installing the meter to remove dirt, sand, and debris.
- Slowly open the upstream isolation valve and allow the meter to fill with water.
- Open a nearby faucet or outlet to release trapped air from the pipeline.
- Once a steady flow of water is achieved, close the faucet.
- Inspect all connections, couplings, and joints for leaks.
- Verify that the meter register is operating correctly and recording flow.
- Confirm the meter is installed horizontally with the register facing upward.
- Ensure no leaks are detected and the meter is accessible for reading and maintenance.
Final Inspection Checklist
Use this checklist before handing over the installation or proceeding to communication setup.
Steps
- Meter installed horizontally.
- Register facing upward.
- Flow direction correct.
- Gaskets properly installed.
- Isolation valves installed.
- No leaks detected.
- Air removed from the pipeline.
- Meter operating normally.
- Meter accessible for reading and maintenance.
Important Installation Notes
Follow these precautions during installation and service.
Steps
- Always flush the pipeline before installing the meter.
- Replace gaskets whenever the meter is removed and reinstalled.
- Protect the meter from physical damage and environmental exposure.
- Ensure adequate clearance around the meter for future maintenance and inspection.
