Torque Tube Density Transmitter
We can offer torque tube liquid density transmitters which utilize the buoyancy exerted on a displacer when immersed in a liquid. The buoyancy on the displacer is proportional to the density and operates on an elastic torque tube which, transforming the applied force in a rotary movement, operates the magnet and consequently the electronic transmitter.
This system is exceptionally accurate and friction free as the torque tube acts also as sealing device towards the pressure of the process fluid whose density is being measured. The instruments are provided with a system for the specific gravity calibration of the measured liquid. They can be also designed for the interface measurement of different liquids or for level measurements.
