100975 TMT Flow Switch – 12 GPM, 3/8" FPT Inlet/Outlet for Hot Water Pressure Washers

100975 TMT Flow Switch – 12 GPM, 3/8" FPT Inlet/Outlet for Hot Water Pressure Washers

The 100975 TMT Flow Switch provides dependable water-flow sensing for burner control on commercial hot water pressure washers. Rated for flow rates up to 12 GPM, this switch features 3/8" Female NPT inlet and outlet connections for easy installation into compatible high-pressure plumbing systems.

The flow switch detects water movement through the pressure washer and provides the switching action needed for burner control, helping ensure the burner operates only when water is flowing through the heating system.

Specifications:

What it does:

The 100975 TMT Flow Switch senses water moving through the pressure washer plumbing. When sufficient flow is detected, the switch changes electrical state to allow the burner control circuit to operate. When water flow stops, the switch changes state again, allowing the burner to shut down.

Why it matters:

A properly functioning flow switch helps prevent:

• Burner operation without adequate water flow

• Heating coil overheating

• Excessively high water temperatures

• Unnecessary burner operation

• Premature heating system damage

With its 12 GPM capacity and 3/8" Female NPT inlet and outlet, the 100975 TMT Flow Switch is a dependable replacement for compatible commercial hot water pressure washer systems.
