Which Equipment Is Needed To Conduct Hydrant Flow Test?
Among others, you need the flow test kit, hydrant wrenches, flow test documentation, and hydrant number. The flow test kit should be inclusive of all the components such as the pitot gauge that is used to assess the pressure levels of the hydrant.
Pitot gauge is one of the most important parts needed to conduct hydrant flow test. It makes it easy to calculate the flow rate to the highest level of GPM (gallons per minute) accuracy. We use this equipment for this reason as we endeavor to provide great results with higher accuracy.
When using pitot gauge, we get psi (pounds per square inch) readings that we can convert to gallons per minute. Such level of knowledge requires professional engineers and we have that covered for you. Pitot is the fastest and the most reliable handheld gauge in testing flow rates. It helps us notice reduced flow rates due to underlying problems such as heavy wall deposits in the pipe.
A pit gauge basically has the blade, handle and the pressure gauge. It is a simple yet most sophisticated tool for hydrant flow testing missions.
When using pitot gauge, we place it within the open hydrant’s water discharge where the narrow tube inside the pitot measures the pressure when water gets in. The gauge captures PSI readings which we will convert into gallons per minute for accurate flow rate readings. PSI readings can help us relate static and residual pressures of the hydrant.
Bernoulli’s principle helps us relate PSI readings to GPM readings. However, the formula can be more complex with the consideration of frictions in the pipe wall because the wall is not always smooth. We then resort to other means to determine the friction co-efficient. The process seems much easier for us as we are experienced in such advanced calculations. It could be too complicated for you.
