AquaTrak 5000

Absolute liquid level sensor

Part # 93083

aquatrak 5000

The AquaTrak 5000 sensor provides accurate measurement of absolute liquid level in all weather conditions. Designed for rugged, unattended operation, the sensor has been field proven in adverse environments around the world for hydrology, oceanography, and hostile environment chemical and nuclear tank control systems.

The AquaTrak’s technology uses ratiometric time comparisons of sequential sonic/pressure pulses that travel inside an environmentally protected PVC tube between the sensor transducer to the liquid. The AquaTrak 5000 controller, which is connected to the data logger, can be located up to 1000 feet from the AquaTrak transducer. The AquaTrak transducer combined with the controller calculates the true average level even in the presence of waves and surging liquid surfaces. The sample rates, number of samples averaged and data requested are selectable. Continuous measurement or exclusive data sets without outlier bias are standard operating routines. Self-calibrated measurement correction for ambient temperature, atmospheric pressure and gas density within the calibrated range(s), yields an accuracy of ± 3mm.

The AquaTrak also uses the US NOS (National Oceanographic Services) standard algorithm to determine the standard deviation for each data set used, which is used in turn to calculate the average wave height during the sample period.

These features have resulted in the AquaTrak becoming the world-wide sensor of choice in GLOSS (Global Sea Level Observing System) tide and sea state measurements.

What's the Easiest and Quickest Way to Start Collecting Data and Access it Anywhere?

The Answer's in the Cloud.

eTracker is a cellular modem and "virtual" cloud-based data logger in one (meaning you don't need to install a separate data logger). Simply connect your sensor and a power source to eTracker and you're done. Configure (or reconfigure) anytime from any Internet-connected device, and use Stevens-Connect to retrieve your data, or forward it to your favorite software system.
