Good day,
At the Refinery, we use a DP Level Transmitter with 1199 Diaphragm Seal System to measure Vacuum tower bottoms in combination with a wet leg for the low pressure sensor (Figure 1). When bottoms level raises over the upper tap (B), wet leg its contaminated and level measurement goes to an unknow value.
We are planning to install an ERS to eliminate the wet leg. Could it work installing the secondary sensor at the upper tap (B)?
