Product Details:

Dwyer Instruments V10 Flotect flow switch is designed for use with motors, pumps, boilers, chillers and water heaters to control & monitor the flow of air, steam or liquid. It automatically starts or stops auxiliary pumps & engines to protect motors and other equipment against low or no flow.

Features:

  • This Dwyer V10 Flotect flow switch features brass construction for corrosion resistance and durability.
  • The hermetically sealed reed switch features magnetically actuated switching mechanism and the field-trimmable, full-size vane offers user convenience.
  • This mini-size unit allows a simple field switch adjustment facility for easy toggle between normally closed and normally open configurations without changing the electrical connections.
  • It has an external switch housing for easy switch changeover and maintenance without interrupting the process flow.
  • The model meets NEMA 4X IP66 enclosure rating for waterproof performance.

Standards and Approvals:

  • CE
  • RoHS
  • UL
  • CSA
  • cUR
  • UR

Frequently Asked Questions:

Q. Can the V10 flow switch be mounted for use in a vertical up-flow application?

A. Yes, the vane on the standard V10 features a spring return that enables attachment in any orientation.

Q. What do actuation and de-actuation mean?

A. Actuation refers to the phenomena when microswitch trips or the contacts of a microswitch change their state. De-actuation occurs when the flow rate is low enough for the microswitch to revert to its default setting.

Q. How to install this Dwyer flow switch?

A.

  • Make sure you carefully unpack the switch and take any packaging out of the lower housing.
  • The vane should be trimmed at the proper mark depending on the pipe size being utilised.
  • Install the switch in the system piping with the arrow on the side pointing in the direction of flow and then apply pipe thread sealant to the 1/2 inch male NPT mounting threads.
  • Install wiring in accordance with regional electrical regulations.
  • When assessing system loads and currents, use caution.
  • After installation, set the switch action to NO (usually open) or NC (normally closed).
  • When a reed switch is activated by an increase in flow, usually closed connections open and normally open contacts close.
  • The two screws on the top cap must be loosened but not removed in order to replace them.
  • To reveal the specified switch action, slide the reed switch assembly.
  • When the adjustment is finished, tighten the screws.

Q. What is the difference between inductive, capacitive and lamp load current ratings?

A.

  • An inductive load is due to an electromagnetic solenoid, electromagnetic relay and electromagnetic counter with an inductive component as a circuit load.
  • A capacitive load is a capacitor connected in series or parallel with reed switch control. In a closed circuit, a cable length, generally greater than 50 metres, is used to connect the reed switch which may also evolve static capacitance.
  • A lamp load can occur because of a tungsten filament lamp load.
