The Levelogger has a 22 mm x 154 mm watertight stainless steel housing with a zirconium nitride coating for corrosion resistance. Incorporating a pressure transducer and temperature sensor and a 10 year battery life, the Levelogger is designed for measuring and logging water levels in a vast range of different scenarios, with real time data viewing and export capability. It can be linked to radio or mobile networks. With a sealed Faraday Cage design, maintenance is simplified and protection is provided against electrical spikes caused by lightning. The Levelogger is an absolute pressure transducer (water pressure + atmospheric pressure) and requires a Barologger for accurate barometric compensation.
