Installation Instructions for Volumetric Piston Water Meters

Protecting the Meter
Start by ensuring all plastic water meters are covered post installation. This protects the meter from direct sunlight, which can be done using a housing or meter box.

Sizing
Make sure the water meter is correctly sized according to the pipe size or the flow rate.

Flushing Pipework
Flush all pipework to remove debris or sand, ensuring a clean pipeline.

Meter Orientation

Install piston meters either horizontally or vertically.

Avoiding Pressure
Ensure no pressure is applied to the meter during installation from misaligned pipes or excessive vibration, which can lead to failure.

Fitting Installation
Avoid over-tightening fittings and excessive use of sealing materials like sealing tape, which can cause leaks.

Thread Treatment
Only use thread tape or PTFE tape, ideally with tailpieces.

Soldering Precautions
Avoid soldering near the meter, especially where brass fittings are involved, to prevent damage from heat.

Water Type
Ensure the meter installed for cold water is not used in a hot water pipeline.

Appropriate Usage
Use the meter only for clean potable water to avoid damage and inaccuracies.

Handling Care

Handle the meter carefully as it is a precision measuring instrument. Do not drop it or break the meter seal.

Thread Fittings
Avoid using tapered thread fittings; Use of tailpieces is preferable.

Additional Protection
Install a strainer before the water meter to protect it from sand or foreign debris.

FAQ

Q: What is a volumetric piston water meter?

A: A volumetric piston water meter is a type of water - measuring device that uses pistons to measure the volume of water passing through it. It operates by trapping and displacing known volumes of water, and counting the number of these displacements to determine the total volume of water consumed.

Q: How does a volumetric piston water meter work?

A: As water enters the meter, it forces pistons to move within chambers. Each piston displacement represents a fixed volume of water. The movement of the pistons is transferred through a mechanical linkage to a register or digital display, which accumulates and shows the total volume of water that has flowed through the meter.

Q: What are the main components of a volumetric piston water meter?

A: Its main components include pistons, measuring chambers, a drive mechanism (such as gears), a register or display unit, and a housing that encloses all these parts and connects to the water pipeline.

Q: How often should a volumetric piston water meter be calibrated?

A: It is recommended to calibrate volumetric piston water meters every 5 - 10 years, depending on factors such as water quality, usage frequency, and the criticality of accurate measurement. In some cases, more frequent calibration may be required if the meter is used in harsh conditions.

Q: What is the typical lifespan of a volumetric piston water meter?

A: With proper installation, regular maintenance, and suitable operating conditions, a volumetric piston water meter can last 10 - 20 years or even longer.

Q: How do you maintain a volumetric piston water meter?

A: Regularly check for leaks around the meter connections. Clean or replace the strainer if installed. Periodically inspect the meter for any signs of wear or damage to the internal components. If the meter is not in use for an extended period, it should be drained to prevent corrosion.
