Our density sensors are based on the floating principle. It allows make quick and exact measurements of the real density of a liquid at any level without sampling. There is a steel float with precise volume and weight inside the sensor. When the sensor is fully immersed into a liquid, the float begins ascending under the influence of buoyancy force of the liquid. The ascendant movement of the float drives the core of a coil of a shift sensor. 

A shift sensor converts the ascending of the float into changing of inductance and then – in changing of voltage. The shift sensor allows to combine the float with electronic converter and to create compact and convenient instrument for precise measurements of the real density at any level of liquid, without sampling.

The floating density meters have a number of advantages. It is enough to immerse the density sensor at the required depth into the liquid and the values of real density and temperature are displayed on the LCD. 

There are the essential differences, which make the floating density meters irreplaceable in field-using or when you want to define the weight of liquid in large tanks:

• they allow to escape the labour-consuming process of sampling;

• they can take measurements of real density and temperature on the depth up to 30 meters in a few seconds;

• the accuracy of portable devices is 0.0005 g/cm3;

• the accuracy of the density measurements is not affected by the liquid’s viscosity;

• they work in a wide temperature range: from –30 °C up to +50 °C;

• they can be used for continuous control of the technological process.
