Mechanical density meter
July 2018, Mass Measurement


Whether dealing with the concentration or the mixing ratio, the density of liquid media is of high importance in processes such as the food or chemical industry. Kobold’s DWF mechanical density meter is designed specifically for the monitoring and continuous measurement of liquid media and 2-phase liquids. Once it is calibrated to the respective medium, the density is measured by means of a float and transmitted to the outside without magnetic contact. Even multi-phase media can be safely managed with this measuring principle.

At 1% of the measuring range, repeatability and linearity of the robust field device are very high. The stainless steel or Hastelloy instrument can stand medium temperatures up to 150°C and pressures up to PN 40. Three different sizes ranging from a maximum of 2500 l/h to a maximum of 10 000 l/h make it possible to adjust the system optimally to the respective task. The nominal widths of the process connections are DN 25 for the smaller device and DN 50 for the two larger devices.

An easy to read mechanical indicator is located directly on the measuring device. The electrical output signal 4... 20 mA is for remote transmission. Additional limit value contacts can also expand the application possibilities as needed with the respective switch outputs and a transducer with communication protocols such as HART, Profibus PA or Foundation Fieldbus. With an IP65 degree of protection, the high quality and robust measurement instrument is very well designed for a harsh process environment. It fulfils industrial norms and standards and is certified for use in explosive areas.

The DWF’s main features include:

• A large spectrum of wetted materials.

• Magneto-resistive signal transmission.

• High temperature application option.

• High pressure application option.

• Excellent heat tracing technology.

The DWF is used for density metering of liquid media in pipes. The scale on the device shows the density rate expressed as grams per litre or kg per mN. Applications include density metering, monitoring and control of liquid media. The DWF is excellent for processes operating under difficult and rough operating conditions. The device is also available with additional electrical equipment for process monitoring and control.
