DF520 Fuel Level Sensor
Outside-mounted ultrasonic level sensing for tanks
DF520 measures liquid level from the outside bottom of a tank. The updated design uses optimized electronics and installation reliability to support cleaner retrofit monitoring for LPG, fuel, diesel, water, and other compatible liquids.
Customer Value
Designed to reduce installation risk and field maintenance
Non-contact Measurement
Ultrasonic sensing reads through the tank wall from outside, avoiding direct contact with the liquid.
Optimized Electronics
The updated circuit design improves weak-signal processing and helps filter clutter in supported tank applications.
Improved Installation
The installation approach has been refined to improve coupling stability and reduce field adjustment effort.
Applications
Suitable for tank monitoring projects
DF520 is useful when the customer needs a cleaner installation method for existing tanks. Confirm tank wall material, wall thickness, medium, and installation position before rollout.
Deployment and Integration
From tank level to actionable data
Level Trend Monitoring
Operators can review remote level status and historical trends for replenishment planning.
Installation Guidance
Project teams should verify the tank bottom surface, coupling method, and wireless signal conditions.
Platform Integration
Dingtek can provide cloud access, customer platform integration, and data protocol support after project confirmation.
FAQ
DF520 Selection FAQ
Does DF520 require drilling into the tank?
DF520 is designed for outside-bottom ultrasonic installation, helping compatible tank projects avoid drilling or direct contact with the liquid.
What measurement range is currently promoted for DF520?
The currently promoted DF520 measurement range is 0-3 m for compatible tank monitoring projects.
What tank wall thickness has been tested?
DF520 has been tested with tank wall thickness up to 10 mm. Tank material, wall thickness, medium, and installation position should be confirmed before procurement.
What has been optimized in the updated DF520 design?
The updated DF520 design uses optimized electronics for weak-signal processing, clutter filtering, improved penetration capability in supported tanks, and improved installation reliability.
