Toshniwal bros offers density /concentration meters. The dimf series density/ concentration meter is based on the oscillating element principle. The fluid to be measured flows through the oscillating element that is excited electro - magnetically and will oscillate at its natural frequency. Changes in the density of the fluid lead to changes in the natural frequency. These frequency changes will be picked up by the electronic transducer and converted into a signal proportional to density or concentration. The measured variable is available as a 420 ma output signal and can be shown on the on-site display. Major applications are process control and quality monitoring of fluids in all areas of industry. The device can also be used for density mass flow conversion for custody transfer in connection with the corresponding volumetric meters and flow computers.
