OPERATION

The Dwyer Mark II Wind Speed Indicator is

100% pneumatic. It operates on the time

proven principle of aircraft speed indicators.

The complete kit consists of a pick up vane

connected by fifty feet of flexible double

column tubing to the Mark II Indicator, plus

all necessary mounting hardware, fluid and

instructions.

In operation, wind aligns the Mark II weath-

er vane pointing the pick up tube into the

wind. Wind pressure enters and is transmit-

ted through plastic connecting tubing to red

fluid inside the indicator. Fluid level rises

and falls in response to changing wind

speed. Scale calibrations on the indicator

show the wind speed corresponding to var-

ious fluid levels. For wind direction, observe

the weather vane position.

INSTALLATION

1. Mount the weather vane assembly out-

doors, as high as possible and away from

the diverting effects of trees, roof pitch, and

other structures. A minimum of 5 to 10 feet

of clearance is recommended for mounting

above small or medium sized buildings and

15 to 20 feet for large buildings. Attach the

mounting bracket directly to the pole or tel-

evision antenna tower with the hardware

provided. It will not interfere with T.V. recep-

tion. Assemble the roof top unit as shown in

diagram on page 3. Use the curved slot to

adjust the pick up unit to a vertical position.

Tighten all screws. Make sure weather vane

rotates freely.

2. Thread the dual column tubing through

slots in the mounting bracket and tape

loosely as necessary to relieve strain.

Separate the two tubes for several inches

and slip the red striped tube over the top

pipe on pick up assembly. The plain tube

slips over the lower pipe.

3. Run tubing to the desired indicator loca-

tion. It can be installed either inside or out-

side. Use plastic tube clamps (Part No. 285)
