Specifications - Installation and Operating Instructions

Rugged and reliable the Flotect®V4 flow switch operates automatically to

protect equipment and pipeline systems against damage from reduction or loss of
flow. The V4 is time tested being installed in thousands of pipelines and processing
plants around the world. A unique magnetically actuated switching design gives
superior performance. There are no bellows, springs, or seals to fail. Instead, a free­swinging vane attracts a magnet within the solid metal switch body, actuating a
snap switch by means of a simple lever arm.

FEATURES

• Leak proof body machined from bar stock

• Choice of custom vane calibrated for your application, Model V4, or field
adjustable multilayer vane, Model V4-2-U (see set point chart on page 4)

• Weatherproof, designed to meet NEMA 4

• Explosion-proof (listing included in specifications)

• Installs directly and easily into pipeline with a thredolet, tee, or flange (see
application drawings on page 4)

• Can be used in pipes 1-1/2˝ and up

• Electrical assembly can be easily replaced without removing the unit from
installation so that the process does not have to be shut down

• High pressure rating of 1000 psig (69 bar) with the brass body and 2000 psig (138
bar) with the 316 SS body

APPLICATIONS

• Protects pumps, motors and other equipment against low or no flow

• Controls sequential operation of pumps

• Automatically starts auxiliary pumps and engines

• Stops liquid cooled engines, machines and processing when coolant
flow is interrupted

• Shuts down burner when air flow through heating coil fails

• Controls dampers according to flow

Notes:

• Check all ratings given in the instructions and on the product to make sure that the
product is suitable for your application. Do not exceed electrical ratings, pressure
ratings, or temperature ratings of the product.

• Disconnect power supply before beginning installation to prevent possible
equipment damage or electrical shock.

MAINTENANCE

Inspect and clean wetted parts at regular intervals. The cover should be in place at
all times to protect the internal components from dirt, dust, and weather, and to
maintain hazardous location ratings. Disconnect device from the supply circuit
before opening to prevent ignition of hazardous atmosphere. Repairs to be
conducted by Dwyer Instruments, Inc. Units in need of repair should be returned to
the factory prepaid.
