Flow metering for Gas, Steam and Liq- Liquid Service In order to consider proper venting or draining location depends on type of media and orientation of pipe. To meter liquids, the entire probe should be filled with liquid allowing gas bubbles to vent off. To allow this to happen, the unit should be installed with a slight downward slope from the dp-transmitter towards the measurement profile Gas Service For gasses, the installation theory is exactly opposite to that of liquids. The deltaflow should be completely filled with the gas, and condensation should be able to drain freely back into...

Flow metering for Gas, Steam and LiqTable 1 DF25 Type Code Type Code in Detail Fluid Code -FG -FL -FF -FD Explanation Please select option FG (Gas) if your medium is a dry gas and neither the conduit nor the ambient pressure contains any condensation to consider. Specifically, dry air and other dried process gasses fall into this category. Option FL (liquid) is the correct choice if your medium is a liquid and if boiling (flashing) is not a consideration in either the conduit or the ambient temperature. This category includes the most common liquids such as water, hydrocarbons, etc. Flashing...

Flow metering for Gas, Steam and Liq-CF -CA -CP -CS Weld-in studs with DIN flanges (option CF) are often used in gauge pressure applications. This model is also well suited to high pressure situations, because the flange uses 4 or more mechanically redundant screws to hold the deltaflow in position. The flange is designed to divert pressure in the event of a leak, thereby preventing media from spurting in the direction of the operator. This means that the flange connection method provides an added measure of safety when the deltaflow is used to meter dangerous media under pressure, such as steam....

Flow metering for Gas, Steam and Liq- nominal diameter must measure at least DN25 (1”), and we would also need a drawing indicating the critical measurements of the existing studs. We are always happy to fulfill special requirements regarding sealing surfaces or materials. Nominal Diameter The deltaflow DF25 can be used within the nominal diameter range of DN65 through DN 2500 (3” to 100”). For other diameter measurements, please select a different deltaflow model (DF8 / DF12 / DF44). Code -DN… Explanation Please specify the nominal diameter of your conduit (metric or ANSI units). Table 4 Model...

Flow metering for Gas, Steam and Liq- Code -WD… Illustration WD Explanation Your deltaflow is custom-built. In order to assure that your deltaflow is ideally suited to your application, we need to know the actual interior diameter and the wall thickness of your conduit. We recommend that this measurement not be taken from your documentation, but rather measured—at the planned sampling site if possible. This is particularly important for applications involving older conduit systems. It is NOT necessary to have this measurement at the bid proposal stage, but it will be required at the time the...

Flow metering for Gas, Steam and Liq-AN2 If you enter option AN2, your deltaflow will come equipped with ½” NPT external thread connections. Here you have to take care about the connection to your transmitter (impulse piping). Can be used for all kind of media. -AOA If you select option AOA, your deltaflow will be equipped with a flange connection acc. to DIN 19213. Advantage: this feature will allow you to flange most differential pressure transducers directly to the unit without any additional signal conduit. This can save a great deal of time and money. Appropriate for use with all media....

Flow metering for Gas, Steam and Liq- Mounting Material (material weld-in parts) Unless you intend to use an existing connection stud, your deltaflow will be delivered with all studs required for Installation (see also process connection). You must select the material for these studs that is appropriate to your application (normally choosen material should be similar to pipe material) Code -MC -ME -MV -MW -MF Explanation Material: Carbon steel (St35.8 or similar) A standard delivery includes weldable studs made of carbon steel. St35.8 material can be welded to almost all common carbon steel pipe...
