HIGH TEMPERATURE FLOW METER

Lake’s High Temperature Flow Meters enable flow monitoring of barrel heating fluids, thermal transfer fluids such as Syltherm® coolant flows, hydraulic circuits, and sub-circuits. Select from aluminum, brass, or stainless steel design for media compatibility requirements. High temperature flow meters are available for air, water, and oil flow measurement with maximum temperature of 600°F.
