Meter runs combine differential pressure sensors with an inlet and outlet section and thus ensure low-interference flow measurement of aggressive and non-aggressive gases, vapors and liquids. They are mainly used in small pipelines, as this is where the influence of disturbances is greatest.
We offer meter runs in numerous designs. We will be happy to assist you in choosing the most suitable design. The meter runs are completely assembled and delivered ready for installation. Optionally for flange mounting or welding.
Our standard for flow measurement in small pipelines, based on a ring chamber orifice with exchangeable measuring insert. The inlet and outlet pipes form a unit with the mounting rings of the ring chamber and are brought up to the measuring disc without any shoulder. In this way, any disruptions can be minimized as best as possible.
With the 94F design, any differential pressure transmitter is flanged into the measuring section. The differential pressure is tapped via the differential pressure transmitter or via nozzles in the inlet and outlet. This design is also suitable for larger pipelines.
Type 94M corresponds to measuring sections with a plug-in diaphragm flanged between measuring flanges (e.g. according to DIN 19214 or ASME B16.36). Here, the advantages of an orifice plate are combined with the advantages of the measuring section.
See orifice platesTypical versions of the pressure nozzles are:
Depending on the application, the measurement uncertainty is approx. 0.5% – 1.5% of the flow coefficient.
Meter runs can be equipped with shut-off valves and/or valve blocks. Condensate vessels are recommended for steam applications.
