Description
3.1 FUP1010 features
Description
The Siemens SITRANS FUP1010 Weatherproof IP67 Portable flow meters achieve highly
accurate flow measurements using ultrasonic transit-time technology. The sensors are
mounted on the outside of the pipe, preventing contact with the medium. This means no
cavities or clogging by high paraffin liquids found in many hydrocarbon applications.
The sensors offer superior performance in terms of volumetric flow accuracy, density
accuracy, and turn-down ratio. The sensor construction makes installation and
commissioning of even the largest sizes very straight forward and easy.
The sensors deliver true multi parameter measurements i.e.: volume flow and temperature.
The flow meter has a degree of protection of IP67.
Note
This operating Instructions manual applies to the following FUP1010 IP67 (weather proof)
operating systems: Version 3.02.00K and later and version 4.03.00 and later.
Portable Configurations
The FUP1010 weatherproof single and dual channel flow meters use a compact and rugged
submersible, weatherproof case. The following portable models are available:
● FUP1010 Weatherproof Single Channel Multi-Function Portable
● FUP1010 Weatherproof Dual Channel/Dual Path Multi-Function Portable

3.2 Applications
FUP1010 IP67 Portable
14 Operating Instructions, 03/2012, A5E02951522-02
Channel Functions
The system software allows simultaneous operation of one channel in the Transit-Time
mode and the other in Reflexor mode.
Transit-Time Mode
All SITRANS F 1010 models use transit-time flow measurement technology varying only in
functionality and environmental housing.
Reflexor Mode
The SITRANS F 1010 transit-time flow meter is highly resistant to the effects of liquid non-
homogeneity caused by the inclusion of air or solid particulate. However, sonic beam
scattering may occur when mineral-based solids or gaseous content is a high percentage of
the volume. This can cause difficulty in operation due to signal attenuation. Liquid conditions
that may be unsuitable for transit-time operation can be measured using the Reflexor mode.
Dual channel portable systems allow operation with one transit-time channel and one
Reflexor channel measuring flow on the same pipe.
3.2 Applications
Measurement of Liquids
SITRANS F flow meters are designed for measurement of a variety of liquids and gases. The
transmitters are multi-parameter devices offering accurate measurement of mass flow,
volume flow, density, and temperature.
Typical Applications
The typical applications of the flowmeter are:
● Fuel Flow Measurement
● Hydraulic Oil Leak Detection
● Measurement of Additives
● Oil & Gas: Filling of gas bottles, furnace control, CNG-dispensers, test separators
● Crude Oil
● Finished Hydrocarbon Products
● Fuel Oil
● Bunker Fuel

● Chemical Processing
● Food and Pharmaceutical
● Aircraft Avionics and Ground Support
● Water and Wastewater
● Aerospace
● Automobile Manufacturing
● Hydrocarbon Industries
3.3 Theory of Operation
The liquid flow meter relies on the MultiPulse transit. Two WideBeam ultrasonic sensors per
measuring path, alternating as transmitter and receiver, are used to interrogate the liquid
flowing within the metering section. The resulting time of arrival for each direction of transmit
(upstream and downstream) is then measured using a highly accurate and stable digital
signal processing method.
Using this detection scheme, the flow meter is capable of resolving the relative transit-time
difference (dT) to within ±100 psec. Considering typical liquid flow transit-time differences
ranging from 1x104 to 1x106 psec, the flow meter is capable of providing an exceptional turn-
down ratio. The flow meter also incorporates a correlation technique which enables the
system to detect very high flow velocities with the same high degree of resolution. The
ultrasonic sensors are designed with sufficient beam divergence characteristics to insure that
the receive sensor will always have sufficient signal to maintain operation under conditions of
high beam blowing associated with high flow velocities.
With accurate signal arrival time available, the flow meter can compute the raw flow velocity
from the measured upstream and downstream transit times.

Flow Profile Compensation
Another important consideration is that the ultrasonic flow meter has to compensate for the
flow profile to maintain calibration accuracy. Shown below is a graphic of a "fully-developed"
flow profile. Note that the fluid velocity increases toward the center (axis) of the flow stream.

The Reynolds number is then computed as follows:
5Q 3LSH,'9 )  
9LVFRVLW\
where viscosity = cS = cP/density
cS = kinematic viscosity
cP = absolute viscosity
The flow meter then uses this computation of Reynolds number to compensate the raw flow
velocity for conditions of laminar or turbulent flow profile as defined by an internal Reynolds
compensation table. The flow meter then converts the compensated flow velocity to
volumetric flow rate.
Rate = VF * Comp(Rn) * Pipe area
Volume Correction Algorithm
The flow meter provides Standard Volume output by inferentially determining the liquid API
@ 60oF (or the specified base temperature) and then applying the API standard (2540)
algorithm as outlined below. Before describing API algorithm the steps required to obtain
bulk or actual flow should be reviewed.
1. Based on the measured transit time difference (Δt), average transit time (TN) and pipe
dimensions, the RAW flow rate (FLOWRAW) and liquid sonic velocity (Vos) are computed.
2. Using the liquid temperature input and the optional user provided pressure input, the
measured Vos is then compensated to the value expected for base temperature and
pressure conditions (i.e. 15.5°C and 1 bara or 60°F 14.7 psia). This compensated Vos is
called LiquIdent.
LiquIdent = Vos + TempSlope * (t - base temp) + PresSlope * (p = base pressure)
where: t = measured temperature (oF)
TempSlope = change in liquid sonic velocity per oF (Linear for petroleum products.)
PresSlope = change in liquid sonic velocity per PSI (Linear for petroleum products.)
LiquIdent provides an output that identifies the liquid independent of the operating
temperature and pressure.
1. Through optimization the LiquIdent values (for a wide range of different liquids) can then
be associated with an API@60oF as well as Viscosity @ 60oF. This information can be
keyed into a lookup table within the flow meter. This table then serves as a reference for
dynamically inferring the liquid properties as different liquid batches enter the flow
transducer. (The lookup function for this table will also interpolate and extrapolate for
values between and outside the table values.)
2. Based on FLOWRAW and the inferred Viscosity, the current Reynolds # is computed. The
Reynolds # value is used to correct the raw flow for non-plug flow profile. The
compensated actual flow rate is then computed (FLOWBULK).
3. The volume correction can now be computed using API standard 2540. Note: 60oF is
used for the base temperature value in the example below, but this can be altered within
the flow meter menu.

a) ρ60 = (141.5 *999.012) / (131.5 + API60)
● where:ρ60 = density at 60oF (Kg/m3)
b) α60 = KO / ρ602 + K1 / ρ60
● where K0 and K1 are coefficients of thermal expansion.
c) ρt =ρ60 * EXP (- α60 Δt (1 + 0.8 α60 Δt))
● where Δt = (t - 60)oF and t = measured temperature
d) Therefore the volume correction factor (VCF) = ρt / ρ60
The final volume compensated flow rate is then: Std Flow = FLOWBULK * VCF
Flow meter Types
The flow meter automatically conditions Installation Menu choices to suit the selected meter
type. The following illustrates the 2-Channel and 2-Path flow meter types.
2-Channel
Dual Channel provides two independent measurement channels that operate
simultaneously. Depending on the specific model, Dual Channel supports: Clamp-on Transit-
time, In-line Transit-time and Reflexor.
