Liquid Density Meters – Operating Principle

Metron Fluid Density Meter - DIMF Oscillation Fork Graphic

Density Meter Oscillation Fork Design

The central sensor component of our density meters is an oscillation element consisting of an oscillation fork or tube.  Flowing liquid passes through the oscillation element which is then electromagnetically excited and oscillates at its characteristic frequency. Changes in density result in changes in the characteristic frequency. These frequency changes are very accurately measured and registered directly by the transmitter.

Liquid Density Meters – Construction

Depending on the corrosive or non-corrosive properties of the fluid you want to measure, these meters are constructed with robust and structurally sound stainless steel, hastelloy, titanium, or tantalum. They operate within caustic environments in many industries.
