The relationship between flow rate (Q) and differential pressure (Δp) is given by a square root function:

Downstream of the Pitot tube the static pressure p

is reduced by the permanent pressure loss Δω. With Pitot

Sizing and optimization The exact relationship between differential pressure, flow and pressure loss is described by the k-factor, which

depends on the shape and size of the Pitot tube. The k-factors of the Deltatop Pitot tubes have been determined and verified in elaborate sample calibrations. Every Pitot tube is shipped with a calculation sheet. The differential pressure, pressure loss, application limits and further parameters are calculated based on the customer specifications. For this purpose, a form (Sizing sheet - data sheet, → ä 49) has to be completed. The user does not have to be involved in complicated sizing calculations.

"Applicator" selection and sizing tool

Endress+Hauser's Applicator software is a convenient selection and sizing tool for planning processes (for details, see booklet IN013F). The Applicator program is available free of charge either in the form of a CD or can be downloaded from the Internet at: http://www.products.endress.com/applicator

Applicator Sizing Flow

The "Applicator Sizing Flow" module calculates all necessary data for the selected primary device:

• Differential pressure

• Pressure loss

• Measuring uncertainty

• k-factor

• Upstream and downstream straight lengths

• Pressure ratings

• Medium parameters

Additional options

• Sizing sheet - data sheet

• Sizing sheet - calculation sheet

• Determination of the mounting position

Sizing sheet - data sheet To ensure that the Deltatop measuring point exactly matches the requirements of the process, the completed

"Sizing sheet - data sheet" (→ ä 49) has to be attached to the order. Endress+Hauser uses the data in this form to determine the optimum configuration of the measuring point. The "Sizing sheet - data sheet" can be generated by the "Applicator" selection and sizing tool.

Selecting the differential pressure transmitter and the measuring cell

If they are ordered together with the primary element, it is possible to order the Deltabar differential pressure transmitter with a suitable measuring cell and calibration even without knowing the complete calculation data. Endress+Hauser will select the most suitable measuring cell based on the calculation results for the Pitot tube. The differential pressure transmitter will be delivered completely configured and preadjusted to the calculated values. This allows easy and convenient ordering and commissioning of the measuring point even for less experienced users.

Temperature and pressure compensation

Separate process connections

Two additional probes are required for temperature and pressure compensation:

• An absolute pressure sensor This sensor must be mounted on the upstream side of the Pitot tube.

• A temperature probe In order to avoid disturbances of the flow profile, this probe must be mounted on the downstream side of the Pitot tube. The minimum distance between the Pitot tube and the temperature probe is 3D. (D: diameter of the pipe)

Combined process connection for absolute pressure, differential pressure and temperature

• Versions of the Deltatop DP72B and DP73B units are available with an integrated Pt100 temperature probe

• In the case of Deltabar S, an adapter (e.g. oval flange PZO) can be used to screw a pressure transmitter or a pressure sensor into the Deltabar S flange. The absolute pressure sensor must be mounted at the "+" side of the Deltabar S.

Calculation of the compensated volume or mass flow

• For steam: Flow and Energy Manager RMS621 for water and steam from Endress+Hauser; for details see Technical Information TI092R

• For all media: Universal Flow and Energy Manager RMC621 for gases, liquids and steam from Endress+Hauser; for details see Technical Information TI098R

• For all media: by a PLC; In this case the compensation calculation has to be programmed by the user.

Calculation formula for temperature and pressure compensation

The starting point for compensation first has to be defined. The starting point is the calculation sheet which accompanies every primary element. Layout data for a specific operating condition (pressure and temperature) can be found on the calculation sheet.

The relationship between flow and differential pressure is described by a square root function:

2 pDr

for the mass flow (or volume flow at normal or standard conditions)

and

2 pD

for the volume flow

where ρ = the density of the medium.

If the current output of the Deltabar transmitter is set to flow values, the square root function is already implemented. Otherwise the square root function must be computed externally, e.g. in a PLC. Please make sure that the square root function is not applied twice.

Whenever the real operating conditions differ from the conditions used in the calculation sheet, the density of the gas will change and thus also the calculated flow rate will change according to the above-mentioned formula.

where P = absolute pressure T = absolute temperature (K) Z = compressibility factor 1 = operating condition according to the calculation sheet 2 = operating condition currently measured

The compressibility factor Z can be neglected if its value is close to 1. If the compressibility factor is to be included in the compensation, the value must be determined according to the pressure and temperature currently measured. Compressibility factors are available in the corresponding literature in tables or graphs or can be calculated using the Soave-Redlich-Kwong procedure for example.

Split range (expansion of the measuring range)

! !

The square root function has a very steep slope in the vicinity of the zero point. Therefore, the measuring range is limited from below, which results in an operable flow range of typically 6:1 (max. 12:1). If the differential pressure is high enough, it is possible to increase the range by connecting multiple differential pressure transmitters with different measuring ranges. The following Endress+Hauser devices can be used to evaluate the measuring signals simultaneously:

• Flow and Energy Manager RMS621 for water and steam (see Technical Information TI092R)

• Universal Flow and Energy Computer RMC621 for gases, liquids and steam (see Technical Information TI098R)

Note! The maximum available operable flow range depends on the differential pressure available.

Note! The same method can be used to implement redundant measurements.

Flow measurements in liquids or steam

With liquid or steam applications, the transmitter must be mounted below the pipe. All impulse pipes must be installed with a slope of at least 1:15 to the process connection - coming from the transmitter. This ensures that trapped air and bubbles rise back to the process pipe and thus do not influence the measurement.

Caution! With steam applications, the differential pressure transmitter must be located at a sufficient distance to allow for cooling to meet the transmitter specification. A typical cooling rate is 100 °F per foot (55 °C per 300 mm).

Flow measurement in gases With gas applications, the transmitter must be mounted above the pipe. All impulse pipes must be installed

with a slope of at least 15:1 to the process connection - coming from the transmitter. This ensures that any condensate flows back into the process pipe and thus does not influence the measurement.

Mounting positions

Versions Compact version

With the compact version of the Deltatop, the Pitot tube, the manifold and the transmitter are delivered readymounted. Additional piping and additional valves are not required. Thus, leakage problems are eliminated.

Remote version

With the remote version of the Deltatop, the Pitot tube, the manifold, the shut-off valves and the transmitter are delivered separately and must be mounted on site. This version is recommended:

• For high process temperatures which make direct transmitter mounting impossible.

• If the transmitter cannot be mounted directly at the Pitot tube due to space restrictions.

Flow direction • The flow direction is indicated by an arrow on the flange plate (compact version) or on the probe head

(remote version).

• "Mounting left" and "Mounting right" refer to the flow direction (see drawings below).

• For compact versions, the transmitter is mounted in such a way that the display can be read in the specified mounting position and does not need to be rotated.

Mechanical construction

Probe profile Developed from aerospace technology, the Deltatop averaging Pitot flow sensor provides unsurpassed accuracy

and reliability. With its solid one-piece construction and bullet shape, the Deltatop makes flow measurement clog-free and precise. The unique sensor shape reduces drag and flow-induced vibration. The location of the low pressure ports eliminates the potential for clogging, hence improving signal stability.

Purge unit

Usage With flow measurements of waste gases or soiled air, solid particles often settle at the profile of the Pitot tube

and, depending on the degree of soiling, reduce the measuring accuracy or even interfere with the functionality of the Pitot tube. In many applications, recurrent manual cleaning of the Pitot tube is not a feasible solution. Demounting the probe, thorough cleaning and remounting are often too cost-intensive and time-consuming. Furthermore, no measuring data are available during the cleaning procedure. The purge unit helps to perform fully automated and effortless cleaning. The application of a purge unit is recommended for a particle concentration of more than 1.17 gr/yd (100 mg/m3). The usability of the purge unit is restricted for humid or adhesive solid particles. The maximum permissible solid content depends on the abrasiveness and size of the particles and has to be examined separately in each case.

System design The purge unit consists mainly of a purging block with a 2-way valve which can be directly triggered. A

customer-provided relay or a PLC can be used to trigger the two solenoid valves.

Mounting 1. The purge unit is directly mounted to the differential pressure transmitter with the supplied screws and

seals.

2. The vent valves supplied together with the differential pressure transmitter are screwed into the purge unit. The impulse pipes are mounted on the opposite side of the transmitter. This ensures that not only the Pitot tube but also the measuring chambers of the differential pressure transmitter are purged and cleared from any deposit.

3. The connections for the purging air are located at the bottom of the purge unit.

Instructions for completing the sizing sheet - data sheet

• The order code of a primary element does not completely describe the final device. Further information is required. The optimized sizing and calculation of the primary element is based on the requested information about process parameters and pipe dimensions etc. Additionally Endress+Hauser checks if the information provided matches the order code of the device. Furthermore, the feasibility of the measuring point also has to be examined. A fully completed questionnaire, including information on the project, order codes and tag number, ensures the correct assignment of primary elements to differential transmitters and accessories during order processing.

• The "Sizing sheet - data sheet" can be filled in and printed using the Endress+Hauser Applicator sizing software. All required data can be entered or are available in the database.

• All fields marked with an asterisk * have to be completed. The order cannot be processed and device production cannot commence before these points are clarified.

• All parameters have to be filled in with their value and the complete and correct unit (e.g. flow rate in Sm h and not m3/h for flow at normal conditions).

For gases only: Values for the flow rate and/or density can be related to the actual operating conditions (nominal pressure and temperature) or to normal or standard conditions. The resulting difference may be large depending on the pressure and temperature. Please check the data carefully. Furthermore, clearly specify the units for the flow rate and density (e.g. flow rate in Sm at normal conditions).

The values for the flow rate or density are related to the nominal process conditions (pressure and temperature).

Reference pressure Reference pressure at standard conditions yes

Req. flow Specification of the desired measuring range (minimum to maximum) and of the operating point

(nominal). The operable flow range is typically between 1:3 and 1:6 (minimum : maximum). An operable flow range of more than 1:10 usually requires cascading (split range) of several differential pressure transmitters (→ ä 8). Too large an operable flow range between the nominal and the maximum flow can result in an increased measuring uncertainty at the operating point and should be avoided.

Pressure Static pressure in the pipe upstream (plus side) of the primary element. yes yes

Temperature Temperature of the fluid at the primary element. yes yes

Fluid properties Clearly defined liquids and gases, such as steam, oxygen, nitrogen, pure water or ethanol, do not

require further fluid property entries. All necessary information about these data is easily accessible in the relevant literature. Mixtures (e.g. natural gas) or brand names (e.g. Shell motor oil) do not provide sufficient information for calculation purposes. More information is required. If the fluid properties of a mixture are not clear, a list of ingredients and their composition can be attached to this datasheet for clarification.The Endress+Hauser Applicator sizing tool provides users with a large medium database with all the necessary fluid properties for a wide variety of fluids.

Density The density is an essential input value of the flow calculation. This field must be completed for

mixtures and brand names.

Viscosity The influence of the viscosity value on the calculation is normally very small but the Reynolds No. is

a function of the viscosity. This may be a limiting factor for the measurement especially with highly viscous liquids.

Z-factor For gases only:

The compressibility factor Z has an influence on the density especially at higher pressures and/or higher temperatures. If the density is given at normal or standard conditions this may have quite a big impact on the calculation result. If this value is not available, the calculation will be performed with the factor set to 1 or, in case of clearly defined mixtures, with a factor calculated or estimated from the ingredients.

Isentropic index For gases only:

The isentropic index (or specific heat ratio) is required to calculate the expansion factor. If the value is not available, the calculation will be performed with standard values:

1.65 for monoatomic gases (e.g. Helium He)

1.4 for diatomic gases (e.g. nitrogen N

1.28 for triatomic gases (e.g. carbon dioxide CO

)

calculating the differential pressure and determines the length of the probe in the pipe. Incorrect specifications when ordering result in corresponding measuring errors or may mean that the probe cannot be mounted properly or cannot be mounted at all. The inner diameter of the pipe is equal to the length of the probe in the pipe. However, the inner diameter is NOT equal to the nominal diameter. A pipe of nominal diameter DN200 according to ISO may have inner diameters between 194 mm and 215 mm depending on the pressure rating. For pipes according to ASME, it suffices to specify the nominal diameter and the schedule number.

With rectangular ducts the inner pipe diameter is replaced by the inner dimensions of the duct (height and width). These dimensions are used to calculate the cross-sectional area, which is needed to calculate the differential pressure. The Pitot tube is usually mounted parallel to the longer side of the rectangular duct. Therefore, this dimension determines the length of the Pitot tube in the pipe. Incorrect specifications when ordering result in corresponding measuring errors or may mean that the probe cannot be mounted properly or cannot be mounted at all.
