I am doing loop checking of dp transmitter. Where calibarted range is :0 to 100 mbar
and flow is minimum:3.1 metercube/hr max : 3.8 metercube/hr
but when i am neumarically calculating, something is going wrong
Flow= k(meter constant)x√ ΔP , our meter constant is 1, process
We always take consideration of motor's start up current for breaker size and cable per NEC. How about the start up power.
Below are two pictures one is riser and the other is start up current graph.
When I did this by software, software also shows the start up MW.
