Understanding Flowmeter Mounting Options

• Top Mount – Installs on top of horizontal piping.
• Vertical Mount – Fits directly into vertical pipe runs.
• Side Mount – Attaches to the side of horizontal pipe when clearance is limited.

Pool Flowmeter FAQs

What does a pool flowmeter do?

A pool flowmeter measures the rate of water flow through your plumbing system, helping ensure proper circulation, filtration, and equipment performance.

Why is correct water flow important?

Proper flow protects equipment like heaters, chlorinators, and filters while ensuring efficient water treatment and balanced pool chemistry.

How do I know which size flowmeter I need?

Flowmeter size is based on your plumbing diameter and system flow rate. Common sizes include 1.5″, 2″, 4″, and 6″ for residential and commercial pools.

What’s the difference between top mount, vertical mount, and side mount flowmeters?

Top mount installs on horizontal pipe, vertical mount fits vertical pipe runs, and side mount attaches to horizontal pipe when vertical clearance is limited.

Can a flowmeter be replaced without cutting plumbing?

Many flowmeters are designed as direct replacements and can be serviced or replaced without modifying existing Schedule 40 PVC plumbing.
