Flow

Flow switches

Flow switches for flow/no-flow detection, alarms, pump protection, cooling circuits, and process control duties.

Products Flow Flow switches

Specifications, switching points, process connections, pressure ratings, materials, outputs, and enclosure options can be supplied according to project requirements.

Paddle flow switch

Paddle flow switches

  • Flow switches for liquid line monitoring, pump protection, cooling circuits, and process interlocks.
  • Available with paddle, rotor, inline, and compact body configurations depending on the installation.
  • Switching range, mounting orientation, process connection, and electrical output can be selected based on the required duty.
  • Suitable options are available for water, cooling water, utility fluids, oil, and selected process media.
  • Pressure rating, temperature rating, enclosure protection, and materials can be matched to the application environment.
  • Optional features may include adjustable switching points, plug connections, analog or pulse outputs, and service accessories.
  • Final selection depends on pipe size, fluid type, flow range, pressure, temperature, and site wiring requirements.

Thermal calorimetric flow switch

Thermal / calorimetric flow switches

  • Electronic flow switches for applications where no moving mechanical paddle is preferred.
  • Calorimetric sensing monitors heat removal at the sensor tip to detect flow or no-flow conditions.
  • Suitable for minimum flow alarms, maximum flow alarms, pump protection, and process protection duties.
  • Switching point, hysteresis, delay timing, and min/max monitoring can be configured according to the application.
  • Available for non-viscous liquids, with oil or gas suitability depending on selected model and process conditions.
  • Sensor length, process adapter, pressure rating, temperature range, and electrical connection can be selected as needed.
  • Useful for compact pipework, machinery, cooling systems, skids, and industrial automation panels.

Piston reed flow switch

Piston / reed flow switches

  • Mechanical flow switches for simple flow-rate supervision and fast no-flow signalling.
  • Magnetically actuated reed contact designs keep the electrical section separate from the mechanical flow path.
  • Suitable for liquid and gas services where a robust on/off flow signal is required.
  • Available with different switch settings, body materials, pressure ratings, mounting orientations, and process connections.
  • Electrical head, connection type, contact rating, and enclosure protection can be selected for the site wiring standard.
  • Low pressure loss and no-calibration options are available depending on the selected design.
  • Final configuration is matched to flow range, media, pressure, temperature, mounting position, and alarm function.
