Flow measuring instruments ... at a glance 4 Energy efficiency and savings 6 You have specific requirements. 14 We have the experts. WIKA worldwide 16 High accuracy is a decisive criterion in many applications for flow measurement, especially in high-tech fields. It creates the conditions for the functionality and cost-effectiveness of each process. In order to fulfil the accuracy requirements consistently, the measuring instruments must be calibrated regularly. Our calibration laboratory can check all types of flow meters, both primary (Venturi tubes, orifice plates) and secondary (MAG and...

Flow measuring instruments ... The most common method for measuring flow is based around the differential pressure principle. It has proven itself and is applicable for all common types of media. The primary flow elements are based on this method of measurement. For applications with liquids, gases and steam, a large selection of these flow measuring instruments are available from WIKA. We combine the flow elements with differential pressure measuring instruments or accessories into efficient and economical complete solutions. Furthermore, on request, we can also assemble other measurement...

Compact and smart We make it easier for our customers to implement their measuring points by supplying ready-made measuring arrangements, consisting of the respective flow element and high-quality measurement technology (differential pressure transmitters, electrical thermometer for temperature compensation). The compact assemblies can be effortlessly integrated into the process. With smart solutions like this, not only do our customers reduce both their acquisition and installation costs, but they also lower their maintenance costs, since the number of leakages can be reduced by up to 70...

Standard products Energy-efficient Differential pressure flow meters generally cause a permanent pressure drop in the process. This must be compensated by additional pumping capacity. The required energy demand for this can increase the annual operating costs, sometimes significantly. HHR flow tubes, Venturi tubes and pitot tubes demonstrate that they can reduce the pressure drop and thus operate energy-efficiently. They have been designed for a wide range of applications.

Flow Ven nozzle turi ozz le Pito t tub e We dge flow met er Ven turi tube A flow measurement with primary elements requires, as a rule, a straight upstream and downstream pipe. This can be comparatively long, depending on the flow conditions and accuracy requirements, and calls for the corresponding space requirement. WIKA has therefore developed flow meters specifically for applications with limited mounting space which also offer a high accuracy without long meter runs. HHR FlowPak The HHR FlowPak flow meter is a technological advancement in flow profile formation. It does not require any...

Special products Critical media For every flow measurement, critical media represent a special challenge. Whether aggressive or highly viscous liquids or erosive slurries: We have a solution for each application with corresponding measurement characteristics and durability. Special orifice plates Quarter circle and conical entrance orifice plates, segmental orifice plates and eccentric orifice plates are, in many cases, the best choice for measuring liquids with low Reynolds numbers and liquids with higher densities. These instruments, which are as simple as they are effective, are proven...

Meter runs For the highest possible accuracy, primary flow elements are generally integrated into the process as meter runs, thus as a unit with upstream and downstream pipes. Meter runs are also available in a threaded design with a flow measurement add-on. If a higher accuracy is required, the instrument must be calibrated. With the implementation of meter runs, WIKA relieves its customers of all effort: Even before the order is placed, our qualified on-site service team records all required dimensions and parameters. We design, build and test the meter run to the desired specification....

Engineered solutions Restriction orifices To correctly perform the measurement task, in some processes, the flow rate must be limited or the pressure reduced. For this purpose, a restriction orifice is installed in the pipeline, either in a single-step design or – particularly in the case of high differential pressures – as a multi-step restrictor. Each restriction orifice is an application-specific solution. It is designed by our experienced specialists, depending on media properties, pressure loss and process data. Performance and dimensions are calculated to exclude the potential...
