Arrowhead Springs Monitoring
Installation
Arrowhead Springs Monitoring


EYASCO designed and installed a remote wireless monitoring system to measure spring flow and water quality in the San Bernardino Mountains. Due to the rugged terrain, the monitoring system employs a network of repeaters and a 22-mile radio link to a cellular modem collection point. Critical data from this system is collected every 30 minutes, and displayed graphically on a password-protected web page.

San Pablo and Suisun Bay

As part of a CalFED monitoring effort, Eyasco Inc., designed and built a network of ten automated monitoring stations to monitor water quality throughout San Pablo Bay and the west Delta. These sensor platforms measured time series data characterizing tidal heights, conductivity, dissolved oxygen and suspended sediment concentrations in ancient and restored tidal marshes. The data was collected in real time every 12 minutes using a network of radios and cellular modems

Snake River Project
Installation
Snake River Project

EYASCO was contracted to design and build a real-time water quality monitoring system to support dredging operations at various reaches within the Snake and Clearwater Rivers. The monitoring system consisted of four floating instrumentation platforms at the dredging sites, and five at the disposal site. Each platform measured and recorded 7 water quality constituents at the top and bottom of the water column: depth, turbidity, ammonia, pH, temperature, DO and conductivity. The data was transferred every hour from the canyon to a server via satellite telemetry. Our Merlin "Data Resource Management" software collected the data and generated web pages and graphics for display via the Internet. The project lasted a little over three months and collected over 1 GB of data!

Countywide Flood Warning/Water Quality Monitoring

Countywide Flood Warning/Water Quality Monitoring

EYASCO designed and installed a network of over 35 monitoring systems throughout Solano County as part of a countywide flood warning and water quality monitoring project. This system replaced a poorly performing system that was no longer receiving support from the manufacturer. Based on the system requirements it was decided to build a radio network that any monitoring system could use to communicate with the host computer. Radio testing consisted of performing a path study for each intended site, and then performing a signal strength and signal-to-noise assessment at each site as the radios were installed. Those stations that could not communicate via the radio network were fitted with CDMA modems. Eyasco assembled and programmed each system in our Aptos, CA facility, and then assisted the client with installation. Eyasco's Merlin software collects the data, provides real-time status of all the stations and transfers the collected data to a SQL Server enterprise database. Real time graphs of critical stations are posted on a web-site for both public (non-password protected) and private consumption.

Taiwan Power Company- Slope monitoring

Taiwan Power Company- Slope monitoring

Eyasco developed and installed an automated slope monitoring system for use at a critical electrical generating facility in Taiwan. Eyasco designed and programmed the data acquisition system and real-time interface for rain gages, piezometers (to measure ground water level), in-place inclinometers and strain gages for monitoring a steep slope above a power house. The data collected from all the monitoring devices was tied into the power house control and alarm system to provide early warning in the event of a slope movement.

Tanker Tracking and Security

Tanker Tracking and Security

EYASCO designed and constructed a system to monitor water tanker security and water quality for drinking water collected from remote spring sites. This system tracks water from its source to the bottling plant and measures water quality in real-time. The monitoring system is used to qualify water for delivery and subsequent bottling. This system employs state-of-the-art data telemetry and RFID technology in a mission-critical application that protects and tracks millions of dollars worth of commodity. Due to its potential to interrupt the supply-chain, the monitoring system had to be 100% reliable, produce no "false alarms", and communicate with users via local area networks as well as the Internet.

Big Springs Temperature Monitoring
Installation
Big Springs Temperature Monitoring

Five remote data stations are installed on the Shasta Big Springs Ranch, which is located in Northern California between the city of Weed and the Oregon border. These stations currently monitor water temperature; one station also monitors air temperature. Three water temperature loggers are deployed in Big Springs Creek, a tributary to the Shasta River and the location of restoration activities that focus on supporting anadromous salmonids species, particularly rearing juvenile coho salmon. Two water temperature stations are located in an irrigation canal which can divert unused water supplies back into Big Springs Creek. These remote temperature sensors enable ranch managers to compare the temperature of the irrigation water to the creek water and decide whether returning unused irrigation water would impair thermal conditions in the creek. As anadromous salmonids are sensitive to water temperature, keeping water temperatures within specified guidelines is critical to ensuring the recovery of these species.
