Station to review any optional sensor’s mount ing instructions that may
modify the standard setup.

b. Each sensor comes equipped with mounting h ar dwar e for a 1”

diameter pipe.

c. The Weather Station stand consists of a 1” diameter stainless steel

cross bar with a T fitting and the mast (two 1” diameter tubes
connected together with a pvc insert). The top piece of the mast has a
T fitting with a 1” stub attached also.

d. Insert the bottom of the mast into a solid base and secure it. Global

Water sells a Tripod for this purpose, WE830.
e. Slide the top of the mast onto the pvc insert to complete the mast.

cross bar is level. NOTE: For best results the cross bar s hould be at

least 8’ above the ground or roof.
g. The Wind Speed and Wind Direction sensors s hould be m ounted on

the opposite ends of the cross bar. Loosen the set screw holding the

Wind Direction sensor in the elbow. Line up t he notches on the Wind

Direction Sensor, turn the sensor unt il the notches face north, and

secure the sensor.
h. The Temperature Sensor and Humidity S ens or ar e pr es s ure fitted

inside the Solar Shield. The Solar Shield has a 1” elbow that mounts

on the stub attached to the top portion of the mast. Place the elbow

on the stub and secure with the set screw.
i. If the mast is in an area of extreme wind it may be necessary t o s ec ur e

the Weather Station with guy wires (not inc luded) .

V. Weather Station Calib ration Infor mation

WE800

a. The Weather Station comes factory calibrated and the sensors are

pre-attached to the Datalogger and if remov ed s hould be r eattached to

the same channel. Refer to the Weather Sensor manual to determine

how often each sensor should have its calibration checked. Refer to

the Datalogger manual for instructions on recalibration.

WE900

a. Each Weather Sensor will have to be calibrated to your PLC, RTU, or

SCADA system. Calibration numbers have been at tached to each

sensor. Refer to the Weather Sensor manual to determine how often

each sensor should have its calibrat ion c hec k ed.

Datalogger enclosure.

b. Loosen the nut so the retaining bolt can be rem ov ed and the fitting can

placed around the mast. Global Water rec ommends that the
Datalogger be attached to the lower port ion of the mast.

c. P lac e the Datalogger on the mast with the cables coming out the

bottom of the unit.

d. Secure the bolt in the fitting and tighten the nut to secure the

Datalogger to the mast.

Barometric Pressure Sensor Mounting In st ruct ions

a. If the Barometric Pressure Sensor was installed at Global Water, it

was installed inside the Datalogger enclosur e.

b. If the sensor is being installed in the f ield Global Water recommends

that it be attached to the lid of the Datalogger with tape in such a way
that the enclosure can open and close freely. The cable c an either be
cut, stripped, and connected to t he Datalogger on a free channel or
the cable can be run out of the enclosure through a f r ee s train relief,
run back into the enclosure through a different strain relief, and
connected to a free channel on the Datalogger.

c. E ns ur e that a strain relief hole is open, or the pressure valv e is open to

allow airflow or the Pressure Sensor will r ead inc or r ec tly.

Solar Radiation Sensor Mounting Instructions

a. The Solar Radiation Sensor comes with mounting hardware similar to

the Wind Direction and Wind Speed Sensors .

b. The T fitting and stub should be mounted on the upper por tion of the

mast and secured at a height and in a direction where the s ens or will
not be shaded by any other sensor of object . Tighten the T fitting’s set
screws with the enclosed hex wrench to secur e the stub in place.

c. The Solar Radiation Sensor has a 1” elbow that mounts on the stub.

Place the elbow on the stub and secure with t he set s c r ew .

d. Use the bubble level and three mount ing s c r ews to level the sensor

and Wind Directions Sensors are to the Eas t and West.

b. Place the Solar Shield with all of it ’s s ens or s in the sam e hem is pher e

you are in (IE if you are in the North hemisphere place it on the North
side)

c. P lac e the Solar Radiation sensor on the side closest to the sun, be

sure to level the sensor to get accurat e r es ults.

d. Place the Solar Panel under the Radiation Sensor and angle it panel

so you get maximum coverage.
