1.3 System description
The UFM 3030 ultrasonic flow meter is a precision instrument designed for linear, bi/directional flow
measurement of liquids. Flow measurement values can be output via the standard analog and-or
pulse/frequency outputs. Via a user friendly operator interface (HMI) the unit can be set up for a
wide range of applications. Next to actual volumetric flowmeasurement the unit can be configured
to perform flow totalization (plus, minus and sum). Also measurement and output of the liquid sonic
velocity can be configured. Optionally the unit can be set to perform one of the following additional
functions:
•Calculate and output corrected standard volumetric or mass flow using the external pressure
and temperature inputs
•Batch function
•Heat function, combining T1, T2 and volume

2 Mechanical installation
2.1 Handling the flowmeter
Important: Do not lift the compact
flowmeter by the signal converter
housing or the terminal box. Check the
weight of the flowmeter as indicated on
the type plate before handling the unit.
When handling the flowmeter avoid hard
blows, jolts or impacts.
Do not place the flowmeter on the signal
converter housing.
2.2 Installation location and position
The UFM 3030 flow meter can be installed in horizontal, slightly ascending or vertical pipelines.
If installed in a horizontal or slightly ascending pipeline, always install the converter or terminal
box in vertical position opposite the flow sensor either with the converter up or down, but never in
horizontal position.

UFM 3030 9
If required the position of the signal converter can be modified by turning the display circuit board
through 90° or 180° to achieve a horizontal position of the display. In addition the signal converter
housing may be turned through 90° opposite the flow sensor.
For an exact description of this procedure, refer to chapter 8.6.
The measuring tube must be completely filled at all times for proper flow measurement, as the
sensors become non-wetted, a loss of signal message will be displayed. There is no damage
when this occurs.
Flow direction. The UFM 3030 is a bi-directional flow meter. Note the indicating arrow for the
positive direction on the flow meter.
It is recommended to protect the signal converter from direct sunlight to prolong the life. Although
no direct damage will occur, installation of a sunshield is advised.
Do not expose the signal converter to excessive vibration. To protect the flowmeter from
excessive vibration support the pipeline on either side of the flow meter.
Make sure there is sufficient room next to the pipe flanges to fit the bolts and nuts.
To achieve the specified accuracy of the flow meter, a straight inlet section of 10 × DN (DN =
meter size) and an outlet section of 5 × DN should be applied.
Normally zero setting is not necessary, but if required the zero point can be checked and the
meter can be re-zeroed under stationary flow conditions (see Function 1.01.03 of the converter
menu). To force zero flow, a shut-off valve should be provided upstream and/or downstream of
the flow sensor.
Mixing different fluid products. Install the flow meter upstream of mixing point or at minimum
distance of 30× DN (DN = meter size) downstream of the mixing point, otherwise the flow
measurement may be unstable.
Ambient temperature all flow meters: -40 to +65°C/ -40 to +149°F
Product temperature compact flowmeter: -25 to +140°C/ -13 F to +284°F
Product temperature separate flowmeter: -25 to +180°C/ -13 to +356°F
Special versions are available for higher process temperatures.
In case of a pipeline running along a wall: please observe a minimum distance between pipe
centreline and the wall of at least 0.5 m (1.6 ft).
2.3 Special installation requirements
To avoid measuring errors and malfunctioning of the flow meter due to gas or air inclusions or an
empty pipe, please observe the following precautions:

10 UFM 3030
Since gas will collect at the highest point of a pipe, installation of the flow meter at that location
should be avoided at all times. Also installation in a down going pipe should be avoided since a
completely filled pipe may not be guaranteed due to cascading affects. Additionally flow profile
distortion is possible.
Long horizontal pipes: install in slightly ascending
pipe section. If not possible, ensure adequate
velocity to prevent air, gas or vapour from
collecting in upper part of flow tube As a partially
filled meter will report higher than actual flow
rates, or not measure (as transducer pairs become
non-wetted).
Open feed or discharge: Install meter in a lowered
section of the pipe to ensure a full pipe condition
through the meter.
Down going pipeline over 5 m (16 ft) length: install
air vent downstream of the flow meter. To prevent
vacuum. While this will not harm the meter, it may
cause gases to come out of solution (cavitate) and
interfere with proper measurements.
Always install control valves downstream of flow
meter in order to avoid cavitation or distortion of
flow profile.
Never install flow meter on a pump suction side in
order to avoid cavitation or flashing in the flow
meter.
2.4 Pipe flanges
Refer to dimensional drawings for flange spacing
and in addition allow for thickness of gaskets.
Install flow meter in line with pipe axis. Pipe flange
faces must be parallel to each other, max.
Permissible deviation: Lmax - Lmin ≤0.5 mm
(0.02").

UFM 3030 11
2.5 Pipes with cathodic protection
Pipes with electric corrosion protection are generally insulated inside and outside so that the fluid
has no conductive connection to ground. The flow meter must be insulated from the pipe. Note
the following when installing the flow meter:
The pipe flanges must be connected to each other using a copper cable (L), but must not be
connected to the flow meter.
The bolts for the flange connections and the gaskets must be insulated. Use sleeves and washers
that are made of insulating material (these must be provided by customer).
1. Flange of flow sensor
2. Gasket
3. Pipe flange
4. Bolt
5. Nut
6. Washer
7. Insulating sleeve
Follow grounding instructions.
Use ≥4 mm2 (≥AWG 10 cable).
Note: No earthing cables are supplied by
KROHNE.
