Yes we do. A well testing company bought several MPFM 2600, 3” meter size, with 3 different venturi sleeves per meter (small, medium and large beta's). This allows them to cover a larger turndown ratio and increase the operating envelope of the meters, which was beneficial for their portable well testing business.
Another example is an Oil and Gas Operator which changed the venturi at well startup as flow rates turned out to be lower than expected. This way they maintained good quality measurements from the MPFM without having to replace the entire meter. So the added value of the insert venturi sleeve is extended service life, extended operating range, and reduces risk and uncertainties when sizing meters based on predicted production forecasts.
