product groupe "autarkon" (differential pressure)

product groupe "autarkon" (differential pressure)   

product group "trikon" (vortex)

as flow meter / energy meter for steam:
• with built-in compensation of pressure and temperature

• small residual pressure loss
• insensitive to contamination





as flow meter / energy meter for steam:
• with integrated pressure and temperature compensation
• small residual pressure loss
• insensitive to contamination
• 
adaption by the opening ratio of the orifice plate to the metrological requirements,
thereby optimum utilization of the available measurement range

High-precision measurements for billing steam 

with differential pressure method

               

with vortex meter

High-precision measurements for billing steam for example consisting of a measuring section with a pressure differential device and a control box with integrated transmitter technology.
This offer highest accuracy and high level of measuring range. The measuring will be designed according to DIN ISO 5167. As needed it is possible to calibrate the whole measuring section on a accredited test bench.
The control box with the integrated transmitter technology will be assembled and checked completely by us.

The measurement uncertainty analysis is for the entire measurement chain.

           

The measuring chain consists of the vortex meter, flow / energy meter, pressure and temperature measurement as well as entry and exit route.
Highest accuracy and dynamic range. The complete vortex meter measuring distance is calibrated on an appropriate, accredited test bench.

The measurement uncertainty analysis is for the entire measurement chain.

High-precision measurements for billing steam with differential pressure method

Advantages

• we deliver pressure differential devices of every description
  (orifice plates, nozzles, venturi tubes) 
• for our measurements there is a legal certainty because of
   traceability on the international engineer standard
   DIN ISO 5167
• for our measurements it is possible to make a plausibility check
  during operating
• long time stability of our products, because of automatically
   hydraulic zero balance and self test

High-precision measurements for billing steam with vortex meter

Advantages
