The Data Dolphin provides the accuracy of a laboratory instrument in the harsh conditions of the field environment. Water-tight connectors provide the interface to water level transmitters, wet sensors, and ultrasonic sensors.

Data is stored in a non-volatile flash memory module that gives long term storage without the fear of losing your data because of dead batteries. The data is stored in a database structure, allowing you to add or delete inputs "on the fly" without having to restart the data logger.

Designed for field use it’s operating temperature range goes from – 40C(-55C special order) to over 75 C and all inputs have static protection and is also sealed inside a NEMA IP-68 water proof case.

Data collection, programming and viewing collected data is a breeze with the Data Dolphin Software. It allows you to view the current status, setup the logger, and generate graphs.

The level transmitter has a variety of applications such as monitoring streams, reservoirs, surface water, or tank levels and can reliably and accurately provide you with consistent readings in a variety of operating conditions. This level transmitter was designed to provide a low-cost, reliable, industrial, submersible probe. Its simple design ensures trouble-free operation, yet provides very accurate readings. The SNR-PP has a stainless steel diaphragm with the option for titanium. 90 kg pull strength Polyethylene shield vented cable can be ordered to desired length, with the sensor including 25 feet standard.

The overflow wet sensor is a durable weather instrument for sewer interconnects, monitoring streams, reservoirs, surface water, vault or tank levels. The SNR-WET has a chemical resistant polyurethane shield around the electrodes. Extremely durable water barrier cable can be ordered in either 25 feet standard size, or a longer 50 foot version.

Also available is an ultrasonic sensor that can provide height of a fluid in such applications as sewer interconnects, reservoirs, and tanks. The ultrasonic has a factory set range for a 4-20mA output that cannot be lost due to power failure or otherwise. Any or all of these sensors make the SLM-320 Level Monitoring Solution a perfect drop in for your application. And with many communication options available, it is perfectly paired with our manhole or in road antennas.
