Fisher 249 Series Cageless Sensors
Fisher 249 cageless sensors are generally used on applications requiring large displacers that are accommodated by large flange connections. Different displacer stem lengths permit lowering the displacer to the desired depth. These sensors are designed to measure changes in liquid level, liquid interface level, or density/specific gravity inside a process vessel using Archimedes’ Principle.
Features
- Few moving parts are used. A knife-edged driver bearing in the sensor helps to provide low-friction operation.
- The torque tube can be replaced without removing the torque tube arm.
