Frequently Asked Questions - WE800 Global Water

How do I set up the WE800 weather station?

First, mount the outdoor sensor on a pole or wall using the included bracket. Insert 3 AA batteries into the main unit and outdoor sensor. Ensure the sensors are within 100 meters of each other. The main unit will automatically sync with the sensor. Refer to the manual for detailed pairing steps.

How often should I replace the batteries?

Batteries typically last up to 12 months under normal conditions. Replace them annually, or when the battery indicator appears on the display. Use high-quality alkaline batteries for best performance.

What is the wireless range of the WE800?

The wireless range is up to 100 meters (328 feet) in open air. Walls and obstacles may reduce range. To improve signal, place the outdoor sensor at a higher location and away from metal objects.

How do I calibrate the rain gauge?

To calibrate, pour a known amount of water (e.g., 20 mm) into the rain gauge funnel. Check the display reading and adjust using the calibration setting in the menu if needed. Standard accuracy is within ±5%.

Can I connect the weather station to my computer?

Yes, the WE800 supports data logging via an SD card or USB connection (optional cable). Insert an SD card to record data, or connect to a PC for real-time monitoring using the included software. Data can be exported to Excel.

What does the barometric pressure trend indicate?

The barometric pressure trend shows changes over the last 1-3 hours. A rising arrow (↑) indicates improving weather, steady (→) means stable conditions, and falling (↓) suggests deteriorating weather, such as approaching storms.

How do I reset the weather station to factory settings?

Press and hold the RESET button on the main unit for 5 seconds using a paperclip. This will clear all data and paired sensors. You will need to re-sync the outdoor sensor after reset.

Why is my outdoor sensor not connecting?

Ensure batteries are inserted correctly and fresh. Check that the sensor is within range and not blocked by large metal objects. Press the SYNC button on the main unit and the sensor simultaneously. If still not connecting, try resetting both units.

How do I clean the weather station sensors?

Use a soft, damp cloth to wipe the main unit display. For outdoor sensors, gently clean the rain gauge funnel with warm water and a soft brush. Do not use abrasive cleaners or solvents. Ensure all parts are dry before reassembly.

Is the WE800 weather station weatherproof?

The outdoor sensor is weatherproof and designed to withstand rain, wind, and sun. The main unit is for indoor use only and should be placed away from direct sunlight and moisture.

II. Inspection

a. The WE800 / WE900 unit was carefully inspected and certified by Global Water's Quality Assurance Team before shipping. If any damage has occurred during shipping, please notify Global Water Instrumentation, Inc. and file a claim with the carrier involved.

Use the checklist to ensure that everything needed to operate the Weather Station was shipped.

III. Description

a. The Global Weather Station is a rugged and reliable system for monitoring and/or recording several weather related sensors. The standard logging model can monitor and record up to seven 4-20 mA sensors and one pulse output sensor, such as a rain gauge.

IV. Installing the Weather Station

a. Please refer to Appendix A and B prior to installing the Weather Station to review any optional sensor's mounting instructions that may modify the standard setup.
b. Each sensor comes equipped with mounting hardware 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.
f. Mount the cross bar to the top of the mast using the attached T fitting. Tighten the set screw with the enclosed hex wrench. Ensure that the

Global Water

800-876-1172 • globalw.com

cross bar is level. NOTE: For best results the cross bar should be at least 8' above the ground or roof.

g. The Wind Speed and Wind Direction sensors should be mounted on the opposite ends of the cross bar. Loosen the set screw holding the Wind Direction sensor in the elbow. Line up the notches on the Wind Direction Sensor, turn the sensor until the notches face north, and secure the sensor.

h. The Temperature Sensor and Humidity Sensor are pressure 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 to secure the Weather Station with guy wires (not included).

V. Weather Station Calibration Information

WE800

a. The Weather Station comes factory calibrated and the sensors are pre-attached to the Datalogger and if removed should be reattached 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 attached to each sensor. Refer to the Weather Sensor manual to determine how often each sensor should have its calibration checked.

X. Appendix A: Optional Equipment Mounting Instructions

Datalogger Mounting Instructions

a. The optional mounting hardware is located on the rear of the Datalogger enclosure.
b. Loosen the nut so the retaining bolt can be removed and the fitting can placed around the mast. Global Water recommends that the Datalogger be attached to the lower portion of the mast.
c. Place 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 Instructions

a. If the Barometric Pressure Sensor was installed at Global Water, it was installed inside the Datalogger enclosure.
b. If the sensor is being installed in the field 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 can either be cut, stripped, and connected to the Datalogger on a free channel or the cable can be run out of the enclosure through a free strain relief, run back into the enclosure through a different strain relief, and connected to a free channel on the Datalogger.
c. Ensure that a strain relief hole is open, or the pressure valve is open to allow airflow or the Pressure Sensor will read incorrectly.

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 portion of the mast and secured at a height and in a direction where the sensor will not be shaded by any other sensor of object. Tighten the T fitting's set screws with the enclosed hex wrench to secure 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 the set screw.
d. Use the bubble level and three mounting screws to level the sensor

Tipping Bucket Mounting Instructions

a. See Tipping Bucket manual for installation instructions.

Solar Panel Mounting Instructions

a. The Solar Panel comes with mounting hardware similar to the Wind Direction and Wind Speed Sensors.
b. The T fitting and stub may be mounted any where on the mast as long as the solar panel faces the sun's general path across the sky, refer to the solar panel manual for further instructions, available online at, www.globalw.com, in the downloads section. Tighten the T fitting's set screws with the enclosed hex wrench to secure the stub in place.

Weather Station Orientation

a. For optimal results set your weather station up so that the Wind Speed and Wind Directions Sensors are to the East and West.
b. Place the Solar Shield with all of it's sensors in the same hemisphere you are in (IE if you are in the North hemisphere place it on the North side)
c. Place the Solar Radiation sensor on the side closest to the sun, be sure to level the sensor to get accurate results.
d. Place the Solar Panel under the Radiation Sensor and angle it panel so you get maximum coverage.
