UB1-025HM Senseca UB1 Flow Switch

The UB1-025HM is a mechanical paddle flow switch from the Senseca UB1 family for monitoring water flow in industrial pipework. Flow deflects a paddle supported by a metal bellows, which actuates a microswitch. The transparent cover allows visual function checks.

Key Features

  • Mechanical paddle-operated microswitch
  • DN 25 nominal pipe size
  • Process connection: R 1 inch male thread
  • Construction: Brass
  • Water switching range: 2.0–2.5 m³/h, as listed for horizontal inward flow with decreasing flow rate
  • Recommended maximum flow (Qmax): 4 m³/h
  • Ingress protection: IP65
  • Optional accessories/configurations may include signal lamp, double contact, M12 connector and aluminium hood; confirm availability when ordering

Technical Specifications

  • Switching contact: changeover microswitch
  • Electrical ratings depend on load type; datasheet lists up to 250 V AC/DC and 6 A for ohmic loads. Follow the datasheet limits for inductive loads and use suitable protective circuitry.
  • Media-contact materials: Brass version; exact seal/elastomer materials vary by version

Applications

Suitable for flow monitoring and flow-proving interlocks in water lines and industrial equipment. Confirm the selected switching range and material compatibility for the intended medium and operating conditions.

Installation and Ordering Notes

  • Standard installation is horizontal with flow inwards. Other positions may be possible, but mounting orientation affects the switching point and range.
  • Provide a straight calming section of 10 × DN at the inlet and outlet.
  • Install a filter if the medium contains dirt or particles.
  • For vibration-prone installations, secure the paddle fixing as recommended by the manufacturer.
  • For the flanged version, the flange seal is not included in the scope of delivery.
  • Specify flow direction, medium and required switching range when ordering.
