What makes the [F78MP Series Air Radar Sensor](http://bindicator.com/products/mp-series-radar/) such a reliable level measurement device? *Its Echo Profile*. The Echo Profile is the output of the product’s True Level Detect software. It is what allows the F78MP Series Air Radar Sensor to skip over obstructions/anomalies in the vessel and register the true level. The True Level Detect software uses a series of activities to ensure the suppression of false echoes in a reading. Those activities are:
## 1. Algorithms
True Level Detect has the capability for many algorithms - the algorithm used depends on the application conditions. The most common algorithm used in the dry bulk solids industry is ALF (**A**rea, **L**argest, **F**irst).
## 2. Auto False-Echo Suppression
True Level Detect uses auto false-echo suppression – in other words, you can set a range and anything outside of that range will be ignored.
## 3. Dynamic TVT (Time Varying Threshold)
This is the threshold, or baseline, that changes dynamically. The TVT is shaped by changes in the bin environment(such as angle of repose, filling/discharging, etc.), material, obstructions in the vessel, and is subject to the algorithm used.
