    Fiscal Metering

    What are you measuring? what is the line Size? What is your desired flow rates? You use the word fiscal, so I assume custody transfer is applicable? www.dlm.co.za: Over Pressure Protection; Flow, Level & Density Measurement; Automation and Control. www.metermatic.co.za: Electronic Presets...

    Custody Transfer of Milk from a TankTruck

    Can someone point me into the right direction? I would like to know if anyone has a system that can be utilised to perform custody transfer from a tank truck to a processing facility, the metering system needs to be truck based and not a stationary receiving system. I am looking at a similar...

    Fire safe Valves

    KhooWL, There is a small difference but actually a big one between fire safe design and fire safe certified. Fire safe design means that the manufacturer used the methodology in their design, but has not actually gone through the steps to get it certified at an approved body, this normally...

    Vapor Recovery Piping

    If you do not have the answer yet; The reason is actually very simple, it all depends on the certain country's API envelope on the tank truck, i.e. in my country the vapour connection is at the rear of the truck hence we can bring the vapour pipe out from the outside of the coaming 9roll over...

    Pumping Rates to/from Truck and Rail Loading/Unloading Areas

    The loading and unloading of tank trucks and RTC's has a couple of considerations. The velocities of hydrocarbons through a certain diameter pipe should generally not exceed 6m/s, i.e. on a 4" pipe you should not exceed 3000l/min, 3" 1500l/min, 6" 6500l/min. Then there are the vapour...

    Tank Floating Roof Removal

    I am not sure how far you are in this process, however it should be relatively simple to remove the old roof. Most IFR's are assembled inside the tank and use the existing inspection hatch in order for the roof pieces to be carried in. After cleaning and degassing, you should be able dis...

    Leak Detection of Petroleum Double-Wall Tank

    Hi Davster01, I also suggest you look at the new OPW iSite, The iSite gives you various options for monitoring the interstitial spaces. In my opinion, the lowest maintenance unit would be a duel hydrocarbon/water sensor. Please visit http://www.opwglobal.com/Product.aspx?pid=349...

    Suction line Air-Elimination

    I might not have been clear enough, I need to drain the whole tank car, I go into "low flow stop" on the preset when there is still 10 000 liters left in the tank car. I should have said "as the rail car gets emptier" This is not the only solution I'm working on, one of the other things might...

    Suction line Air-Elimination

    I am decanting hydrocarbons from rail cars into storage, the suction line is 4", into a 4" flow meter with an air-eliminator downstream of the pump which has a feed to a downstream valve that will close when air is detected. The problem I have is that my pumps are higher than the lowest part of...
