System Installation and Start-up
1 Introduction
1.1Cautions
Only for flowmeters supplied with a voltage over 50 VAC.
Refer all maintenance or service to trained KROHNE service engineers.
Mains power shall be disconnected from the product before performing any maintenance.
This product is prepared for and can only function with the rated AC mains or DC supply voltage as indicated on the nameplate.
For 100 – 240 VAC supplied flowmeters: this product is a Class 1 device (earthed) and requires a correct connection to protective earth. The protective earth conductor of the main power shall be properly connected to the marked protective earth terminal to ensure safety from electric shock for the operator and its environment. For detail refer to this service handbook.
1.2Unpacking and inspection
•This product has been thoroughly inspected and tested before shipment and is ready for operation.
•After carefully unpacking, inspect for shipping damage before attempting to operate. If any indication of mechanical damage is found contact immediately the responsible transport service and your local KROHNE representative.
•A simple operating check of the electronics after unpacking and before permanent installation is advisable to ascertain whether it has suffered damage during shipment. Confirm for the correct mains voltage printed on the nameplate. If it differs from the ordered product please contact your local KROHNE representative.
•After connecting to the mains, check if there is any indication on the display and if the backlight of the display is lighted. If not, contact your local KROHNE representative for advice.
1.3System description
The UFM 3030 ultrasonic flowmeter 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 flow measurement 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
•Batching
•Heat measurement

1.4CE Approvals
EMC, Electromagnetic Compatibility Directive
EMC directive 89/336/EEC.
Low Voltage Directive
73/23/EEC and is designed in accordance with EN IEC 61010-1 first and second edition.
Pressure Equipment Directive 97/23/EC / Module H
2 Mechanical Installation
2.1Handling 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.
2.2Installation location and position
If required the position of the signal converter can be modified by turning the display through 90° or 180°
Keep measuring tube completely filled at all times for proper flow measurement. Non-wetted sensors

show loss of signal. There is no damage when this occurs.
Flow direction. The UFM 3030 is a bi-directional flowmeter. Note the indicating arrow for the positive direction on the flowmeter.
In case of direct sunlight, we recommend installation of a sunshield to prolong the life of the meter. No direct damage will occur without a sunshield.
Do not expose the signal converter to excessive vibration. For this, support the pipeline on either side of the flowmeter.
To achieve the specified accuracy, ensure a straight inlet section of 10 × DN (DN = meter size) and an outlet section of 5 × DN.
Mixing different fluid products. Install the flowmeter 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 flowmeters: Product temperature compact flowmeter: Product temperature separate flowmeter:
-40 to +65°C/ -40 to +149°F -25 to +140°C/ -13 F to +284°F -25 to +180°C/ -13 to +356°F
a minimum distance between pipe centreline and any adjacent wall of at least 0.5 m (1.6 ft).
2.3Special installation requirements
To avoid measuring errors and malfunctioning of the flowmeter due to gas or air inclusions or an empty pipe, please observe the following precautions:
Since gas will collect at the highest point of a pipe, installation of the flowmeter 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 flowmeter 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 flowmeter in order to avoid cavitation or distortion of flow profile.
Never install flowmeter on a pump suction side in order to avoid cavitation or flashing in the flowmeter.
2.4Pipe flanges
Refer to dimensional drawings for flange spacing and in addition allow for thickness of gaskets. Install flowmeter in line with pipe axis. Pipe flange faces must be parallel to each other, max. Permissible deviation: Lmax - Lmin ≤ 0.5 mm (0.02").
2.5Pipes 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 flowmeter must be insulated from the pipe. Note the following when installing the flowmeter:
The pipe flanges must be connected to each other using a copper cable (L), but must not be connected to the flowmeter.
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).

2.Pipe flange
3.Gasket
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.
