Flow Metering for Gas, Steam, and Liquids

Inner Diameter and Wall Thickness: The deltaflow device is custom-built, requiring precise measurements of the conduit’s inner diameter and wall thickness. These measurements should be taken at the planned sampling site, especially for older systems, and are necessary at the order placement stage.

DP-Connection Options: Various connection options are available for transferring differential pressure to the dp-transmitter, including welding ends (AAN), NPT thread connections (AN2), flange connections (AOA), and more. Each option is suitable for different media types and installation requirements.

Mounting Material: The deltaflow can be delivered with various mounting materials, such as carbon steel for standard applications or stainless steel for corrosive environments. The choice depends on the application’s temperature, pressure, and corrosive conditions.

Material of Profile/Probe: The deltaflow’s profile is made of high-grade steel to ensure accuracy and resistance to mechanical and chemical demands. Options include standard high-grade steel (SEE), high chemical resistance materials (SVE), and high-temperature steel (SXE).

Insulation: Insulation options are available based on the thickness of the conduit’s insulation, with specific codes for different insulation levels.

Nominal Pressure: For spool pieces with flange ends, the nominal pressure must be specified to ensure compatibility with the application’s pressure requirements.

Pipe Orientation: The installation position of the deltaflow varies based on the medium (gas, liquid, steam) and pipe orientation (vertical or horizontal) to ensure proper drainage or venting.

Pipe Orientation 2: For configurations with temperature and pressure measurements, the flow direction must be specified to ensure accurate measurement placement.

Temperature Measurement Options:

PT100 Thermometers: Available with or without 4-20mA transmitters, suitable for temperatures up to 400°C or 600°C, depending on the model. Some models require a spool piece for integration.
Thermocouple Type K: Includes 4-20mA transmitters, suitable for temperatures up to 1000°C, and requires a spool piece for integration.
Custom Options: Available upon request.

Pressure Measurement Options:

Preparation for Pressure Measurement: Includes mounting studs and adapter sleeves, with options for manometer valves and steam siphons. Requires a spool piece for integration.
Absolute Pressure Transmitters: Available with 4-20mA two-wire connections, with or without shut-off valves, and options for steam siphons for steam applications.
Custom Options: Available upon request.

Ex-Approval Certifications:

Temperature and pressure measurement devices can be delivered with or without Ex-approval, with specific certifications available.

Installation Guidelines:

Upstream & Downstream Distances: The document provides a table of required distances for installation with and without the use of the ImproveIT database, which allows for shorter inlet runs.

Flow metering for gas, steam and liquids 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 liquids Type Code in Detail Fluid Code -FG -FL -FD Designation Please select option FG (Gas) if your medium is a gas 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 is not generally an issue except in situations involving high temperatures or liquid gasses. If your medium is (water-based) steam, then Option FD is the correct choice. Table 2 Model Code – Media...
