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 & Revised DP.
Generally we calibrate our transmitter as per the datasheet of orifice. But sometimes the measured DP of transmitter will be out of range or more than maximum scale of DP then we have to re-range the DP flow transmitter.
For these applications we use the below mentioned formula to calculate the maximum flow of 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 & Revised DP must be in same units like bar, mbar, mmh20 etc.
2. The Existing Flow & Revised Flow must be in same units like m3/hr, t/hr etc.
