Product Details

Overview

Tank monitoring becomes unreliable when products are corrosive, pressurized, or prone to buildup that interferes with traditional sensors. Non-contact radar measurement avoids these challenges by reading levels without touching the product, helping maintain accuracy across a wide range of tank materials and operating conditions.

Bluetooth-enabled setup streamlines installation. Once deployed, SmartTank ST705 Radar Monitor connects seamlessly to the SmartTank Portal, where teams can access live level readings, historical usage trends, and automated alerts in real time. Built-in analytics and forecasting tools help turn that insight into action, supporting better planning for industrial liquids, fuels, chemicals, and water.
