Differential pressure flow meters
DDM
DDM-DS11
DDM-EM
DDW-DS31
SMB
Fields of use
DDM / DDW
- plant engineering
- furnace systems
- cooling circuits
- monitoring of liquids for OEMs (original equipment manufacturer)
SMB
- stationary sprinkler systems
Application
These devices are manufactured with a wide variety of nominal widths. Units with small nominal widths such as DDM / DDW are applied in cooling circuits and monitoring of liquids. The sprinkler orifice plate SMB is installed in stationary sprinkler systems and has been approved by the VdS damage prevention.
Media
- water
- air
- transparent and non-transparent liquids and gases
- non-conductive fluids (mineral oils, demineralised water)
Operating principle
A differential pressure arises at a pipe constriction, which is proportional to the square of the flow rate through the pipe. The resulting differential pressure can be recorded with a meter and can be directly indicated as flow rate on a scale.
Products
Kirchner und Tochter offers a wide range of well approved methods of flow measurement.
