Product Information
Product Description
Ensure Accurate Tank Level Monitoring With Reliable Industrial Sensing Technology. The AKCP Tank Depth Pressure Sensor (TDPS) hangs inside the tank and measures the hydrostatic pressure of the liquid column above it. Your AKCP base unit converts that pressure into a live level reading, shown as a percentage or as volume.
Calibrated for tanks from 2 to 20 m
Choose the variant calibrated to your tank: 2, 5, 10, 15, or 20 m. The 2 m model reports in 1% steps. The 5–20 m models report in 0.1% steps, so small changes stay visible in large tanks. Full-scale accuracy is ±0.5%, and water measurements hold 0.2% accuracy across the full 20 m range.
Configured for your tank and fluid
Setup happens in the web interface of your sensorProbe+, securityProbe+, or E-Sensor8. Select the fluid type (water, gasoline/petrol, or diesel), then choose linear for vertical tanks or non-linear for horizontal cylinders and other irregular shapes. Preset tank geometries cover common designs, and manual configuration lets you enter volume at 20%, 40%, 60%, and 80% for custom tanks.
Alerts before tanks run low
Set 5 alarm thresholds, from low critical to high critical, and the base unit sends notifications by SNMP (Simple Network Management Protocol), email, or SMS. A configurable continuous-time delay of up to 65,535 seconds filters out false alarms during refills or unstable conditions. Use it to schedule deliveries before tanks run low, catch leaks or theft early, and track consumption over time.
Simple installation
Installation requires a single 30 mm opening and 4 M5 bolts. The IP68-rated sensor runs on an included 12 V power supply and connects to the base unit through a compact converter box and standard network cable, up to 30 m (100 ft) away.
Common uses include:
- Low level alerts for scheduling refills
- Monitor for leaks
- Theft identification
- Recording usage over time
- Comparing usage with cost
Note: This sensor requires an AKCP sensorProbe+, securityProbe+, or E-Sensor8. It is not compatible with legacy sensorProbe or securityProbe units.
Frequently Asked Questions
Which length should I order?
Match the variant to the maximum liquid depth in your tank, then confirm it fits your fluid. Gasoline and diesel are lighter than water, so each model’s maximum range changes with the fluid: the 20 m model measures up to 20 m of water, 15 m of gasoline, or 16.6 m of diesel. Ratings are based on clear water at 4°C, and other fluids or temperatures can shift readings slightly. If your tank falls between sizes, choose the next size up.
Which AKCP controllers work with the TDPS?
The TDPS works with sensorProbe+ and securityProbe+ base units and the E-Sensor8 expansion module. It does not work with legacy sensorProbe or securityProbe units.
Can the TDPS measure horizontal or irregularly shaped tanks?
Yes. During set up, select Non-Linear in the tank configuration and choose a preset geometry, such as a horizontal cylinder. For custom shapes, enter the volume at 20%, 40%, 60%, and 80% full, and the base unit calculates the level from there.
How is the TDPS sensor installed?
Mark the tank depth on the leader cable, then drill a 30 mm hole and 4 threaded M5 holes in the top of the tank. Thread the cable through the mounting plate’s cable gland and lower the sensor so it hangs about 1-3 cm above the tank floor. Bolt down the plate and seal the edges with silicone.
How far can the TDPS sensor be from the base unit?
The converter box connects to the base unit with standard network cable up to 30 m (100 ft). A 15 ft CAT6 extension cable is included.
