In Figure 9.4 (a) can be seen images of the reservoir / tank water. There are water depth h, water discharge of Qin and discharge water out of Qout. Greater than the incoming water we can not predict. It could be a huge Qin Qin is very small or even no flow at all. Water Reservoirs Figure 2.4 (a) and ...

Sampling Nozzle procedure can be used for fuel sampling light from the retailer to the type of dispenser. Procedure: – As soon as possible after the fuel is pumped and the pump has been reset connect the pump nozzle with nozzle extension – Fill sample container slowly through the nozzle extension, up to 70-85% container capacity – Move the nozzle ...

Position measurement can be done by analog and digital. For a shift that is not too far away measurements can be done using analog means, while for longer shift distance it is better to use digital way. Position or displacement sensor results can be used to measure linear or angular displacement. Technical treatment of the sensor can be done by ...

In the study of engineering, we need to define additional terms are necessary to describe control systems, such as: plant, disturbances, feedback control, and a feedback control system. The following will be given definitions. Then a description of the system is a closed loop and open loop, and also the advantages and shortcomings compared to the open loop control system ...

1. Bottle Sampling: – This procedure can be used for the sampling of fuel with RVP 105 kPa (16 psia) or less in tank cars, storage tanks, tank ships and barges – System equipment is recommended as shown in Figure 3, it is recommended the bottle cap diameter 19 mm (3/4 in) – Procedure: a. All-levels sample: Lower the cap ...

A. Running / All-Level Sampling Application: Running and All-level sampling may be used for sampling fluids which have RPV  101 kPa (14.7 psia) in a tank truck, shore tanks, ship tanks. Running and All-level representative sampling is not necessary because of the volume of the tank is not proportional to its depth and because the operator can not raise ...
