Global Water's WL400 Water Level Sensor provides highly accurate water level measurement for a wide variety of applications, including those in severe environments. The submersible pressure transducers have a dynamic temperature compensation system, enabling high accuracy measurements over a wide temperature range. The water level sensor is easily adapted to all dataloggers, telemetry, monitoring equipment, and displays.

Each of the water level sensors consist of a solid state submersible pressure transducer encapsulated in a stainless steel 13/16 inch diameter housing. The water level sensor has a molded waterproof cable and a two-wire 4-20mA output for connection to a monitoring device. A 25 ft cable is standard, and optional cable lengths are available up to 500 ft.

The Water Level Sensor's submersible pressure transducer is fully encapsulated with marine-grade epoxy so that moisture can never leak in or work its way down the vent tube to cause drift or level sensor failure. The sensor uses a unique, highly flexible silicon diaphragm to interface between water and the sensing element. This silicon diaphragm protects the water level sensor's electronics from moisture and provides each sensor with exceptional linearity and very low hysteresis.

Water level ranges of 0-3, 0-15, 0-30, 0-60, 0-120, and 0-250 feet are available. The 0-3 ft low-level range is ideal for measuring shallow flows or small water level changes like those encountered in sewers, storm drains, weirs, and flumes. The 0-3 ft water monitoring sensor accurately measures small changes in water, even when the water's depth is only a few inches deep.
Questions & Answers
Is this sensor difficult to maintain?

No, but standard care and calibration methods are suggested. The screen on the end of the sensor should be periodically checked for clogging from mud, sludge, and other debris. If it is fouled, wash the screen with clean water and/or scrub it gently with a toothbrush. Do not insert objects through the screen, as this may cause damage to the sensor. Global Water recommends verifying the sensor's calibration with a sounder or other measuring device once every 6 months

The Frozen Frontier: Chasing Data in Antarctica

For Paul Savoy, sailing on the Nathaniel B. Palmer research vessel as part of the United States Antarctic Program (USAP) has been a dream come true, a “mountain top” for his career. “I grew up reading about the age of exploration, and the great polar explorers back in the day. Antarctica is one of the last remaining frontiers, along with the deep ocean and outer space. I was delighted to discover Antarctic research covers all three, with deep ocean research happening on the icebreakers and cosmological experiments at the South Pole. I’ve been applying for a job down here since I was 18. I got shortlisted a few times, but never actually got picked up until I was 32. Now I’m 35, and finally headed to the ice.

New Environmental Sensors and Data Acquisition Knowledge Base

NexSens Technology has worked for over two decades to simplify complex environmental data acquisition systems. The core components of these systems have always been the development of data loggers, configuration and data management software, and simplified sensor integrations. NexSens is excited to bring a new dimension to another critical aspect of real-time environmental monitoring: environmental sensors and data acquisition documentation through the revamped online Knowledge Base. The Knowledge Base serves as a living library, featuring the most thorough information, start-up instructions, integration guides, and other documentation available for NexSens systems and products.

The Tiniest Cars: Understanding the Effects of Microplastics on Coral

Like the microplastics she studies, Keiko Wilkins arrived at this point in her life through a long, multi-dimensional, and at times unexpected journey. Today she is a second-year graduate student in the doctoral program at the University of Hawaii , a graduate assistant at Kewalo Marine Laboratory , but her journey began in Pickerington, Ohio, a far cry from the sea. “I always had an interest in water, and I swam competitively,” she recalls. “I knew I wanted to study biology, but did I want to do research or education? So I explored biology further. My academic advisor worked on lakes and I focused on zooplankton in lakes, and changes in their populations. Fascinated by the ocean, I wanted to study it, but in Ohio, the ocean is, of course, out of reach.
