RBDM liquid Densimeter can be used in a range of industries including processing ... materials or in the food industry for measuring the concentration of moisture ... They are suitable for measuring liquid and are based on the proven tuning fork technology. It is an all-welded sensor that is designed for insertion into a pipeline, open tank, or closed tank. Fluid density is determined directly from the resonant frequency of the tuning fork immersed in the fluid. A temperature sensor is also fitted within the transmitter to indicate the operating temperature.
