Pipe
The U1000 V2 consists of an electronics module (3) and a guide rail (4), which together form a
single unit which is fixed to the pipe (6) by pipe clamps (2).
The U1000 V2 is supplied with power through an external 12 – 24 V power adapter (1).
5.2 Principle of operation
The U1000 V2 takes accurate flow measurements by determining the difference between the
transmission times of two ultrasound signals.
Page 7
Design and function Instruction manual
6
A periodic voltage pulse acts on the transducer crystals and produces an ultrasound beam at
a certain frequency. The beam is first transmitted by the downstream transducer (blue) to the
upstream transducer (red).
The beam is then sent in the opposite direction, i.e. from the upstream transducer (red) to the
downstream transducer (blue). The time taken for the ultrasound to pass through the liquid in
this direction is slightly shortened by the speed at which the liquid flows through the pipe.
The resulting time difference T1 – T2 is directly proportional to the speed at which the liquid
flows through the pipe.

8 Installation
8.1 Positioning the transducers
The U1000 V2 requires an even and uniform flow profile, since distortions in the flow can
cause unpredictable measurement errors.
In many applications, however, it is not possible to have a uniform flow rate through 360°.
This may be, for example, because there are air bubbles inside the top of the pipe, or
turbulence in the pipe, or sludge at the bottom of the pipe.
Experience has shown that the most accurate results are obtained if the guide rail of the
transducers is not mounted vertically to the pipe, but turned at an angle of about 45° to the
right or left on the pipe.

Incorrect measurements
Measurements can be distorted if the transducers are positioned close to upstream pipe
components and fittings such as pipe bends, T-branches, valves, pumps and similar
obstacles.
To ensure that the U1000 V2 is positioned at a place that has an undistorted flow profile, the
transducers must be mounted sufficiently far from possible sources of distortion to prevent
these from having any effect on the measurement.
Install a straight section of pipe with length 20 times the diameter on the upstream side
of the transducer.
In exceptional cases, a pipe with length 10 times the diameter may be sufficient.
Install a pipe section with length 10 times the diameter on the downstream side of the
transducer.
In exceptional cases, a pipe with length 5 times the diameter may be sufficient.
8.2 Preparation
Before attaching the transducers, make sure that desired position meets the distance
requirements.
See Section 8.1 Positioning the transducers, Page 9.
Clean the pipe to remove any grease residues.
Remove any dirt and flaking paint in order to ensure an even surface.
Maximum accuracy
A smooth and even contact between pipe surface and transducer is an important factor for
obtaining a sufficiently strong ultrasound signal.
8.3 Start-Up

pipe correctly.
See also section 13 Troubleshooting for further
advice.
8.4 Adjusting the sensor distance
Maximum accuracy
The two sensors must be placed at defined distance relative to each other, where the
distance depends on the pipe inside diameter and pipe material.
Define optimal sensor distance with entering your pipe credentials in the U1000 V2 start-
up wizard (see section 8.3 Start-Up). (E.g. B-4 for PVC-U pipe with 50 mm inside diameter)
Loosen the sensor mounting screws.

8.7 Electrical connection of the U1000 V2
The U1000 V2 operates in the voltage range 12 – 24 V (AC/DC). The power supply must have a
minimum rating of 7 VA per instrument. To fully meet the requirements of EMC regulations,
a 12 V connection is recommended for domestic and light industrial applications.
For full immunity to electrical interference the screen of the power/pulse output cable and
modbus cable should be connected to Earth.
For safety, connecting the U1000 V2 to a power supply via a mains rated transformer is the
responsibility of the installer to conform to the regional voltage safety directives.
Connect the external power supply to the Brown and Blue wires of the six-core cable.

9.2 Setting the pulse output
The pulse output can be set in two different operating modes:
Volume based mode
After a measured volume of 10 l (preset value), a pulse is sent => 1 pulse/10 l.
The maximum number of pulses that can be sent without storing is calculated using the
two default parameters Vol per pulse =1 and Pulse width = 25 ms, with the formula
1/(0.025x2) giving a value of 20 pulses/s.
If the volume flow in the pipe is so high that more than 20 pulses/s are generated, a pulse
overload error may occur if the number of stored pulses exceed a value of 1,000.
To avoid this, the Vol per pulse value can be adjusted as necessary.
See Section 10 Password-protected menus, Page 23.
Frequency based mode
In frequency-based mode, the pulse output frequency is proportional to the volume flow
within a frequency range of 0 – 200 Hz.
9.3 Current output 4 - 20 mA
The preset output value of 4 - 20 mA is active if the 4 - 20 mA LED is lit.
The preset flow value for the 20 mA output is calculated automatically according to the set
pipe size.
The preset flow value for the 4 mA output is 0. To change this, see Section 10 Password-
protected menus, Page 23.
If the flow value is greater than the value set for the 20 mA output, or there is negative
flow, or a flow signal cannot be detected, then an alarm current of 3.5 mA is generated.
The 4- 20 mA current output is pre-calibrated ex works.
9.4 Modbus
The Modbus RTU interface is configured via the Modbus sub menu in the password controlled
menu.
The data rate can be selected in the range 1200 to 38400 baud.
The address can be set in the range 1 to 126.
Polling Rate 1000ms (1sec). Time out after 5 seconds.
The instrument responds to the “read holding registers” request (CMD 03).
If the flow reading is invalid then the flow value will be zero.
If a temperature sensor goes out of range then the value will go to -11.
Both of these faults will set the relevant status bit.The following registers are available.

11 Diagnosis
The diagnosis menu provides additional information and various diagnosis options.
In the diagnosis menu, the keypad is less responsive than in normal operating mode. The
buttons therefore have to be pressed for a longer time.
The estimated transmission time (Est. TA) and
actual transmission time (Act. TA) are
displayed. There should be a certain ratio
between these two values.
If the frequency-based option (pulse
frequency) is selected, the present pulse
output frequency is displayed, proportional to
the flow rate.
This screen will display the errors. A number
between 0-255 will be displayed. If no errors
reported "None" is displayed.
The flow board's software version is shown on
the upper line. The lower line shows its
status.
The software version (Rev.) and serial number
(S/N) of the U1000 V2.
The gain factor is displayed as an indication of
signal strength and switch setting. The values
for a good signal 600 – 970 and switch setting
(x1).
The current time difference (DT) between
upstream and downstream signals in [1 ns =
