SENSECA MR1K-008GM004 Flow Switch – Brass G 1/4, 0.4–4 L/min

MR1K-008GM004 Flow Switch – Brass G 1/4, 0.4–4 L/min

The MR1K-008GM004 Flow Switch is a compact mechanical flow switch designed for reliable flow monitoring and switching in liquid media. It features a brass construction, G 1/4 female process connection and DN8 nominal size, making it suitable for compact fluid-flow applications where dependable switching performance is required.

The MR1K flow switch uses a spring-supported piston with magnetic triggering of a reed switch. When the flow reaches the defined switching point, the piston movement actuates the magnetic reed-switch mechanism to provide an electrical switching signal.

The MR1K-008GM004 has a standard switching range of 0.4–4 L/min for water (H₂O) under the specified horizontal installation and flow conditions. The switching head can be adjusted lengthwise when required to set the switching value, after which it is secured in position.

Technical Information

The MR1K series is designed for reliable mechanical flow detection. The manufacturer’s datasheet specifies brass medium-contact construction using CW614N nickel-plated/CW614N materials, along with hard ferrite and NBR components. The standard installation is horizontal with inward flow from the left; installation position can affect the switching point and switching range.

For correct selection, specify the flow direction, medium and required switching range. For viscous media, the manufacturer recommends providing the viscosity, temperature and medium details.

Applications

The MR1K-008GM004 can be considered for equipment and systems requiring mechanical flow monitoring or flow-dependent switching, including:

• Water-flow monitoring systems
• Fluid circulation systems
• Industrial machinery
• Cooling and process-water systems
• Pump and fluid-handling equipment
• Flow-dependent control systems
• Industrial automation and equipment protection

Note: Actual suitability depends on the fluid, operating conditions, flow direction, temperature, pressure and electrical load. Refer to the manufacturer’s technical specifications before selection and installation.
