Servo instrument with high precision measurement of level, interface and density for liquid.
Predecessor model: Proservo NMS5
Servo instrument with high precision measurement of level, interface and density for liquid.
A small displacer is accurately positioned in a liquid medium using a servo motor. The displacer is then suspended on a measuring wire which is wound onto a finely grooved drum housing. When the displacer is lowered and touches a liquid, the weight of the displacer is reduced by liquid buoyancy force. As a result, torque in the magnetic coupling changes, which is measured by 5 sets of Hall sensors.
