Density meter
- Purely mechanical density measurement and monitoring of liquids in pipelines
- No bypass needed
- Rugged design
- Clear 90°-scale
- Transmitter with HART or PROFIBUS-PA optional
The DWF meter is suitable for density measurement of liquid products in pipelines. The current density is displayed in grams per liter or kg/m³ on the scale of the display unit. On request scale according to customer requirement.
Applications
Density meter for liquid media in pipelines. Applicable in all branches of industry due to the use of corrosion-resistant wetted parts.
Reliability
Robust, mechanical measuring method with magnetic measured value transmission clear 90° scale
Special features
- Inline density measurement of liquids
- Linear scale
- No bypass needed
- Wetted parts made of stainless steel
- Heating possible
- For the use in hazardous areas
