ETI... Providing Quality Instrumentation for Hydrological and Meteorological Applications Since 1975

ETI is a leading provider of:

All-weather precipitation gauges

    Scour Monitors that measure streambed erosion around bridge piers

       and abutments

ETI has the right measurement system to:

Measure snowfall accumulation in remote mountainous areas,

    Detect heavy rainfall in a tropical rain forest, or

        Alert authorities if the streambed around a bridge pier or abutment

          begins to wash away

ETI measurement systems are deployed throughout the world.

We relay information from remote data sensors to your headquarters PC over a variety of telecommunications, including:

Cellular and landline telephone,

    Meteor burst RF, and

        GOES and low-earth-orbit satellite systems

Research and Development Contributions...

Acquisition of data for hydrological and meteorological systems has been a primary function of ETI since its founding in 1975. ETI's major activities include design and fabrication of electronic instrumentation systems that measure streambed scour, stream stage, stream velocity, bridge tilt and precipitation. Systems design of ETI products employ state-of-the-art techniques, including spread-spectrum telemetry, satellite and digital cellular telephone communications, and digitized voice response alerts.

Gerald R. Price is the President of ETI Instrument Systems, Inc. He has coauthored several National Cooperative Highway Research Programs, including:

NCHRP Report 515, Portable Scour Monitoring Equipment

NCHRP Report 396, Instrumentation for Measuring Scour at Bridge Piers and Abutments

NCHRP Report 397A, Sonar Scour Monitor

NCHRP Report 397B, Magnetic Sliding Collar Monitor

Mr. Price also has been Principal Investigator on a number of design and development contracts and projects. These include:

The National Weather Service's Automated Surface Observation System (ASOS), wherein ETI designed and developed an all-weather precipitation gauge

The National Weather Service's Small Business Innovative Research Project for Precipitation Measurement

The Meteorological Surface Observation Network (MESONET) automatic precipitation gauge system and remote memory gauge

Dam Automation Systems developed for the Bureau of Reclamation
