This article defines what a project charter is and why it is important. The project charter is a document that identifies your project vision and creates a fluid path for your project team. Identifying your objectives, stakeholders, methods, parameters, risks, and resources launches you on your way to project success.
The DPD is a method that uses colorimetric detection as a means to measure the amount of chlorine in a system. It stands for N,N-diethyl-p-phenylendiamine sulfate and the reaction between DPD and active halogens is what is detected and measured.
DP flowmeters measure the drop in pressure across a flow element in the piping, such as an orifice plate. The measured flowrate is a function of the pressure drop. So the flowmeter consists of the flow element in the piping, as well as a nearby differential-pressure meter. Small tubes, called impulse lines, on either side of the flow element lead to the DP meter for measurement.
