The uniform-flow tube flowmeter requires an increased range
Thread Content
There is a constant-flow tube flow meter whose designed range is too small to meet the process requirements; when the process operates at full capacity, the differential pressure exceeds the range limit. Is it possible to directly change the range of the secondary gauge without replacing either the original gauge or the secondary gauge itself?
It’s possible. Unlike orifice plates, mass flow meters only require the parameters to be recalculated and entered into the transmitter; you can provide the data to the manufacturer for recalculation, and then adjust the transmitter accordingly. Another question: is a constant-flow tube flow meter an Anubas or a Pitot tube? I can no longer understand what a market is; could you all, experts, please help me out?
The prerequisite for changing the range is to recalculate based on the process parameters and select a differential pressure transmitter with a range within an appropriate limit. Under normal circumstances, non-standard throttling components are calibrated at the time of manufacture.
There is almost no need to contact the manufacturer; if the range of measurement needs to be increased only to a limited extent, there is no need to replace the transmitter either – simply calculate the desired range value using the formula and enter it into the transmitter. This flow meter is not accurate to begin with; in fact, the upper limit for the pressure difference is estimated based on the reasonable values for the material.

The design was too small, but it’s actually larger? It depends on the actual flow rate and differential pressure ranges. Once those actual values are known, compare them with those of the shut-off element and the transmitter; if everything is within the specified limits, then changes can be made. If any value exceeds the limit, that component needs to be replaced
