  Vertical Float and Displacer Switches

  Vertical Float and Displacer Switches

  For extreme conditions, this vertically mounted hermetically sealed switch provides dependable control.  Specifically designed to handle corrosive atmospheres and low temperatures, the magnet switch mechanism provides a positive snap shut action.  With less moving parts there is less maintenance and greater reliability.  This product is ATEX accredited.

  Key Features

  • No springs in switch mechanism – positive snap action switching
  • Vibration resistant – eliminates spurious trips
  • Multiple switch point options – cost effective control
  • Genuine hermetically-sealed switch option – totally safe and secure
  • Extensive range of chambers – suitable for most applications
  • Relevant chambers are supplied CE marked and fully compliant with the Pressure Equipment Directive (97/23/EC)
  • Designed to ASME B31.3
  • Weld procedures approved to EN ISO 15614-1 and ASME IX
  • SIL Certified

  Vibrating Fork Level Switch for Solids and Liquids – DMS & DMT

  Vibrating Fork Level Switch for Solids and Liquids – DMS & DMT

  The Vibrating Fork Level Switch (DMS & DMT series) is the perfect completion of Delta Mobrey’s range of level detection solutions. This instrument completes the range of products for the control of level in tank, silos and pump protection. Solid products like grains or aggregate can be controlled with the Vibrating Rod (VLS), and the application can be expanded to granules and powders with the Vibrating Fork series.

  The same is also available for the controls of liquids, in combination with the Ultrasonic series 003 and all the mechanical float types.

  The vibrating forks are energized and kept in resonance by an electronic circuit. When covered by material, the damping of the vibration is detected by the electronics, which switch the output relay after a configurable time delay. The vibrating fork level switch is the perfect solution for single point level switching in free flowing solids and liquids across a wide density range, covering all the needs from industrial applications to the compactness requirements typical of the applications on machines.

  Key Features

  • Configurable action
  • Threaded or flanged connection
  • Side or top mounting
  • Compact and mini construction available
  • Robust aluminium housing
  • IP67 ingress protection
  • AC or DC supply voltages
  • ATEX approved

  Boiler Water Level Controls

  Boiler Water Level Controls

  This family of Boiler Water Level Controls are designed to regulate the flow of feed water into the boiler in proportion to the steam demand by using the change in boiler level as a load indicator. They consist of the following elements:

  Modulating Controller:

  The Delta Mobrey Modulating Controller is a single element electro-hydraulic control with an electronic feedback, used for controlling the flow of feed water into the boiler. Designed to be used alongside the Delta Mobrey
  Vertical Air Break Controls (VABC).

  Sequencing blowdown valves:

  The Delta Mobrey sequencing valve is designed to function as a combined water isolating valve and a sequencing blowdown valve to provide positive purging of the water connection, float chamber and steam connection of a boiler control. The operation of the valve helps to ensure the water port does not become blocked by sediment, mud or debris. It also provides a positive test of the boiler water level control, ensuring that any associated equipment, such as the feedwater pump or valve, and any alarms, cutouts or lockouts operate as expected.

  Vertical Air Break Controls

  The Delta Mobrey Vertical Air Break Controls (VABC) are a comprehensive range of magnetically operated water level controls for steam boilers. They are designed to meet all requirements for automatic on/off control of boiler feed pump, burner cut out, high and/or low level alarm or any combination of these. Models available with Industrial (NEMA4) or Marine Heads. TÜV approved models are available in chambers and for direct mounting. The Delta Mobrey VABC is a gland-less construction. A primary permanent magnet is attached to the float rod and slides vertically inside a non-magnetic stainless steel centre tube. Movements of the float are transmitted to a secondary magnet in each switch unit.
