Dwyer Series AFS Piston Adjustable Flow Switch

Dwyer Series AFS Piston Adjustable Flow Switch

Flow includes Flow Transmitters, Flow Sensors, Flowmeters, Sight Flow Indicators and Water Meters. Mass Flowmeters, Controllers, Flow Indicators and Controllers are ideal for measurement of flow rates. Flow Switches come as paddle, thermal, piezo, and shuttle/piston. Flow Switch Sensors with an electrical contact output at a specific flow rate have different types of switches, which are paddle, thermal, piezo, and shuttle/piston.

Shuttle or piston flow switches are sensors with an electrical contact output at a specific flow rate. Models are used with oil, air, water and gases. Applications include oil flow control, low flow detection in cooling lines, and high pressure lubrication systems. Rugged construction and excellent chemical compatibility simplify flow/no flow detection. The Series AFS Adjustable Flow Switches are externally adjustable piston-type flow switches for oils, liquids and gases. This Series offers an infinite number of flow settings from 0.5 to 20 GPM.

Features

  • Externally adjustable flow set point
  • Offers a number of flow settings at pressures up to 1000 psig, with low pressure drop and precise repeatability

Application

  • Protecting machine tools from coolant flow failure
  • Protecting bearings from loss of lubricant
  • Assuring proper air flow
  • Water or compatible liquid control
  • Oil flow control
  • Control of gas flows
