DP Flow Transmitter Re-Range: This tool is used to calculate the DP Flow transmitter revised flow with the following inputs: Existing DP, Existing Flow, and revised DP.
This tool is primarily used for orifice-based flow meters. Also useful for flow transmitters that work on Differential Pressure applications.
Generally, we calibrate our transmitter as per the datasheet of the orifice. But sometimes the measured DP of the transmitter will be out of range or more than the maximum scale of DP, so we have to re-range the DP flow transmitter.
For these applications, we use the below-mentioned formula to calculate the maximum flow of the transmitter.
DP Flow Transmitter Re-Ranging
This calculation tool is used to calculate the revised flow range of a DP Flow transmitter.
The formula for calculating the DP Flow Transmitter Re-Range value.
Existing DP = DP value as per orifice datasheet
Existing Flow = Flow value as per orifice datasheet
Revised DP = Actual DP value in the field
Revised Flow = Calculated transmitter flow max range.
1. The Existing DP and revised DP must be in the same units like bar, mbar, mmh20, etc.
2. The Existing Flow and revised Flow must be in the same units like m3/hr, t/hr, etc.
