Flow meters- electronic - Import export

Large heat and flow meters are often used continuously for decades after an initial calibration at external test benches. A recalibration of these meters within their actual operation conditions was not possible so far. In the best case scenario those flow meters are unmounted and recalibrated on an external test bench. Drawback of this method is an interruption of supply in addition to its already high costs. Furthermore, calibration conditions can differ greatly from actual operation conditions compared to test bench conditions, so even if calibrated, the measurement uncertainty in operation remains fairly unknown. This often leads to more difficult fluid distribution optimizations and leaves billing fairness to a gamble. More precisely measured values of flow sensors may uncover hidden saving potentials within the fluid distribution system and allow more exact performance indicators, improving energy efficiency.

The AVI-MAG (or MULTI-MAG for Russia & CIS-countries) is a hot tap full profile electromagnetic insertion flow meter. Multiple electrodes placed across the entire sensor body at equal area, measure and report the average flow rate over the full diameter of the pipe. The specific design of the multi-electrode sensor compensates for variable flow profiles, including swirl and turbulent conditions and allows installation without calibration on site. The AVI-MAG can be installed without shutting down, emptying or cutting the pipe (hot tap installation). It does not require welding flanges and installation can be done in pressurized pipelines up to 16 bar. Cost of installation is largely reduced by eliminating the need for heavy equipment (cranes, etc.) or extensive manpower. The AVI-MAG is the most economical flow metering solution for medium and large pipe sensor sizes, reducing drastically installation costs.
