Versatile flow measurement

Flow Measurement & Control
When it comes to flow measurement, operators have the choice of a large variety of methods. Measurement using differential pressure is deemed particularly reliable and robust, where both the pressure transmitter and primary elements are required for a complete measuring point.
Jumo offers two systems available in a wide range of variants. Application areas can be found in the steel, glass and power industries, as well as in water and wastewater engineering and chemical plants. Other uses include ancillary plants to measure compressed air, steam or other media.
In both versions, the core element is the Jumo flow Trans DP R flowmeter, which can be used in liquids, gases and steam. It is available in numerous nominal widths for a temperature range of -200 to 1000°C and pressures up to 420 bar. The differential pressure is acquired with the Jumo dTrans P02/p20 Delta differential transmitter and converted into a proportional flow signal.
Meter run with ring chamber taps (R01)
This meter run R01 is used for nominal widths up to DN 40. It is also a primary element with ring chamber taps that has mounted inlet and outlet sections. The measuring insert is implemented as a standard orifice plate according to ISO 5167-2 and also in accordance with the respective operating conditions. Other forms of orifice plates are available upon request. The meter runs are completely assembled and delivered ready-to-install. As a result, possible measuring inaccuracies due to installation faults are reduced.
Orifice plate with individual pressure taps (R02)
For orifice plates DN 50 and DN 1000 the one plate RO2 is used. The measuring insert is designed as a standard orifice plate and cannot be exchanged. The compact design allows for the direct installation of the valve manifold and differential pressure transmitter on the primary element. Installation costs are reduced because differential pressure pipes do not need to be mounted. Jumo flow Trans DP R02 is available in a compact or remote mount design type.
