Frequently Asked Questions - WE900 Global Water

How do I calibrate the WE900 weather station for my system?

Each sensor must be calibrated to your PLC, RTU, or SCADA system using the calibration numbers attached to the sensor. Refer to the Weather Sensor manual for calibration frequency and instructions.

What sensors are included with the WE900?

The WE900 includes wind speed, wind direction, temperature, and humidity sensors. Optional accessories like rain gauge, barometric pressure sensor, and solar radiation sensor can be added.

Can I use the WE900 without a datalogger?

Yes, the WE900 outputs analog 4-20 mA signals and pulse output, so it can be connected directly to a PLC, RTU, or SCADA system without a dedicated datalogger.

How should I orient the wind direction sensor?

Loosen the set screw on the wind direction sensor, rotate the sensor until the notches face north, then tighten the screw. This ensures accurate wind direction readings.

What is the recommended mounting height for the weather station?

For best results, mount the crossbar at least 8 feet above the ground or roof to minimize turbulence and obstructions.

How do I clean and maintain the weather station?

Periodically clean the stand with soap and water. For sensor maintenance, refer to the individual Weather Sensor manual.

What is the warranty period for the WE900?

Global Water warrants the WE900 to be free from defects in material and workmanship for one year from the date of shipment.

How can I get technical support for my weather station?

Call Global Water technical support at 800-876-1172 (US) or [phone], or email [e-mail]. Have your model number, serial number, and purchase order ready.

Can I mount additional sensors like a solar radiation sensor?

Yes, optional sensors such as solar radiation, barometric pressure, and rain gauge can be mounted. The solar radiation sensor uses a 1-inch elbow and should be placed where it won't be shaded.

What should I do if the weather station is damaged during shipping?

Contact Global Water immediately and file a claim with the carrier. Use the checklist to verify all components were shipped.

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

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.

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.
