Global Water’s Evaporation Pan is built to be compatible with all standard National Weather Service pan evaporation measurements. The EP180 is a Class A Evaporation Pan that features a drain plug and an attached stilling well for easy installation of a water level sensor, like Global Water’s WL400 (3 ft range). The EP180 is normally installed on a wooden platform set on level ground. There are two commonly used procedures for making evaporation measurements. In both procedures, a 10 inch Deep x 47-1/2 inch ID stainless steel pan (like the EP180) is used to hold the water. Since the amount of evaporation is a function of temperature, humidity, wind, and other conditions, in order to relate the evaporation to current or expected conditions, the maximum and minimum temperature of the water and the amount of air passage are normally recorded along with the evaporation. Global Water offers water level sensors, water temperature sensors, weather sensors, and datalogging capabilities to complete an evaporation monitoring system.
The sensor is easy to install directly within a plant. To install, the sensor should be hung within the plant from its cable at the location where leaf wetness needs to be monitored. The angle of the sensor should be set to approximately the same angle as that of the leaves that are being monitored
With minimal care, the tipping bucket will provide many years of services. All Global Water tipping buckets were designed by the National Weather Service to provide a low-investment, reliable, industrial, tipping bucket rain gauge. Its simple design assures trouble-free operation, yet provides accurate rainfall measurements. The tipping bucket has an 8 inch (20.3 cm); orifice and is shipped complete with mounting brackets and 25 ft (7.6 m) of two-conductor cable. The tipping bucket sensor mechanism activates a sealed reed switch that produces a contact closure for each 0.01″ or 0.2 mm of rainfall. The tipping bucket rain gauge can be pole mounted or bolted to a level plate. Global Water’s GL500 Tipping Bucket Data Logger adds recording capabilities to the RG600 Tipping Bucket. The datalogger connects to the tipping bucket’s pulse output to record data. In addition, Global Water offers the RG700 4-20mA Output Tipping Bucket Converter Module to convert the tipping bucket’s pulse output to a current output for use with recording systems that receive 4-20mA signals.
The raingauges are appropriate for a variety of applications, including stormwater runoff monitoring, rainfall monitoring studies, and soil moisture studies. With minimal care, the raingauges will provide many years of service. The raingauge’s simple design assures trouble-free operation, yet provides accurate rainfall measurements. Raingauges can be pole mounted using thier included mounting hardware.
With minimal care, the rain gauge will provide many years of service. All rain gauges are constructed of high impact UV-protected plastic to provide reliable, low-cost rainfall monitoring. The simplicity of the rain gauge design assures trouble-free operation, yet provides accurate rainfall measurements. RG200 rain gauges have a 6 inch orifice and are shipped complete with mounting brackets and 40 ft of two-conductor cable. The rain gauge sensor mechanism activates a sealed reed switch that produces a contact closure for each 0.01 inch or 0.25 mm of rainfall. Global Water’s iRIS 150 rain gauge data logger adds recording capabilities to the RG200 rain gauge. The datalogger connects to the rain gauge’s pulse output to record data. In addition, Global Water offers the RG700 4-20mA Output Rain Gauge Converter Module to convert the rain gauge’s pulse output to a current output for use with recording systems that receive 4-20mA signals.
Designed for general meteorological applications, Global Water Weather Stations are rugged and low-cost systems for a variety of weather monitoring applications, including: Agriculture Education Environmental Studies Landfills Reclamation Wastewater Facilities Water Budget Analysis Water Conservation
The temperaturehumidity dataloggers have a large display panel (LCD), are operated with a lithium battery and are programmed by using a PC. A temperaturehumidity datalogger interface is required, along with the Winlog basic software, to program the dataloggers. The temperaturehumidity datalogger interface is connected to the PC by a Universal Serial Bus (USB) cable for convenience.
With the temperature data logger you can measure and store up to 27,000 temperature data values with a sample setting from one second to 24 hours per reading. The sampling rate (interval) and ambient temperature have influence on the life span of the temperature data logger’s battery, which can last up to five years depending on use. The EBI 100-T101 temperature data logger measures up to 185°F (85°C), while the EBI 100-T100 temperature data loggers measure up to 302°F (150°C). To program the temperature data loggers the user needs the WINLOG software and the EBI IF 100-1 temperature data logger interface.
The surface temperature sensor’s output is 4-20 mA with a two wire configuration. Each of the surface temperature sensors is mounted on 25 ft of marine grade cable, with lengths up to 500 ft available upon request. The surface temperature sensor’s electronics are completely encapsulated in marine grade epoxy within an ABS plastic housing.
Humidity sensors are composed of a solid state capacitative element with a linear amplifier. The humidity sensor output is 4-20 mA with a three wire configuration. The Global Water Temperature Sensor is a high quality, rugged instrument, precision RTD calibrated to US National Standards. The temperature sensor output is 4-20 mA with a two wire configuration. Each sensor is mounted on 25 ft of marine grade cable, with lengths up to 500 ft available upon request. The electronics are completely encapsulated in marine grade epoxy within a stainless steel housing. The Global Water Solar Shield is a ventilated sun shield, with high reflectiveness, low heat retention, and low thermoconductivity. The unit is designed to protect the Global Water Humidity and Temperature sensors from direct sunlight that may affect the sensor’s 4-20 mA output.
