Flotect Flow Switches
Flotect Series V10 Flow Switch
Proof of Flow or No Flow in 1/2” to 2” Pipe — Low Cost — Leak Proof Body — Weatherproof
Flotect Series V10
The Flotect Series V10 Flow Switch is designed to provide an inexpensive, reliable unit to monitor the presence or absence of flow in a system. The V10 flow switch is used to monitor unattended equipment and protect it from costly damage.
The V10 utilizes a rugged, hermetically sealed reed switch encapsulated in a polypropylene switch housing that fits into a standard heavy-duty leak-proof brass body or optional 303 Stainless Steel body. The switch adjustment allows the user to change the switch to Normally Open (NO) or Normally Closed (NC) in the field merely by loosening two screws.
The switch housing is located outside the process media, making switch change-over or maintenance easy without interruption of process flow. Perfect for proving flow in boilers, hot water heaters, and chillers.

Application Examples
- Boiler flow verification
- Hot water heater protection
- Chiller flow monitoring
- Monitoring presence or absence of flow in unattended systems
- Protecting equipment from costly damage due to flow loss
- Low-cost flow/no-flow detection in small pipelines
Trimmable Vane & Installation Template
A full-size, trimmable stainless steel vane is provided with a removable laminated template calibrated for brass or ductile iron reducing tees and forged steel straight tee/bushing combinations. This allows field installation in pipelines from 1/2” to 2” diameter without special tools or factory pre-configuration.
