Most reliable LEVEL TRANSMITTERS are GWR or Guided Wave Radar type transmitters. They have no movable parts and are not wetted by the process fluids under normal operation. Hence have a long life.
On the lower end we have position transducers working on the principles of flotation.
Also magnetostrictive type are common in industries and comes at a lower cost.
