Introduction
I. Shipping and storage; product inspection
Shipping and storage
The device is to be safeguarded against dampness, contamination (especially the inside of the flow meter),
impact and damage. Open the packaging with caution to prevent unintentional damage.
Adhere to the temperature limits during storage.
Product inspection
Upon receipt of the product, check the contents of the box and the product particulars against the
information on the delivery slip and order form so as to ensure that all ordered components have been
supplied. Notify us of any shipping damage immediately upon receipt of the product. Any damage claim
received at a later time will not be honoured.
II. Warranty
Your flowmeter was manufactured in accordance with the highest quality standards and was thoroughly
tested prior to shipment. However, in the event any problem arises with your device, we will be happy to
resolve the problem for you as quickly as possible under the terms of the warranty, which can be found in
the terms and conditions of delivery. Your warranty will only be honoured if the device was installed and
operated in accordance with the instructions for your device. Any mounting, commissioning and/or
maintenance work is to be carried out by qualified and authorized technicians only.
III. Maintenance, Repair and Hazardous substances
When used in the intended manner no special maintenance is required. However, the flowmeter should be
checked within the context of routine maintenance of the facility and the pipelines. Should a repair,
calibration or maintenance become necessary, be sure to clean the device thoroughly and follow the steps in
section 11 “Returning the Meter”. before returning the device to Heinrichs Messtechnik.
The operator is liable for any substance removal or personal damage costs arising from inadequate cleaning
of a device sent for repair.
IV. Disposal
Observe the regulations applicable to disposal in the country of installation!
V. Supplementary operating instructions
Supplement operating manuals are available for special features, interfaces and operations relating to your
device, request your copy from our service department.

1Steps prior to operation
It is essential that you read these operating instructions before installing and
operating the device. The device is to be installed and serviced by a qualified
technician only. The UMF2B transmitter is to be used exclusively to measure volume
flow or flow velocity, in conjunction with a Heinrichs Messtechnik EPS, PIT or PITE
sensor.

3Application
The magnetic-inductive flow velocity sensor PIT-UMF2 is used to measure or monitor the volume flow of
liquids with and without solids concentration, slurries, pastes and other electrically conductive media while
minimizing pressure drops. The medium must possess a conductivity of at least 20 µS/cm.
Pressure, temperature, density and viscosity do not affect the volume measurements. Smaller portions of
solid particles and small gas bubbles are also measured as part of the volume flow. A larger number of solid
particles or gas bubbles will lead to failures. Special electrodes are available for media that tend to form
greasy films or crusts.

4Mode of Operation and System Design
4.1 Mode of operation
It was back in 1832 that Faraday suggested utilizing the principle of electromagnetic induction for
measuring flow velocities. His experiments in the Thames, though unsuccessful due to superimposed
polarization effects, are nonetheless regarded as the first ones in the field of magnetic-inductive flow
measurement.
According to Faraday’s law of electromagnetic induction, an electrical field E is produced in a conductive
liquid moving through a magnetic field B at a velocity v in accordance with the vector product E = [v x B]. A
liquid at flow velocity v and a flow rate Q flows through a meter tube (4), producing a measuring-circuit
voltage Um at the two electrodes (E1 and E2) at right angles to the direction of flow and the magnetic field B
generated by the field coils (3). The size of this measuring-circuit voltage is proportional to the mean flow
velocity and thus the volume flow rate.

4.2 System design
The magnetic-inductive PIT-UMF2 flow measurement system consists of a sensor (PIT), which picks up an
induced measuring signal from the medium flowing through the pipe, and a transmitter (UMF2), which
transforms this signal in standardized output signals (4-20 mA or pulses).
The PIT-*** sensor can be operated with all transmitters for magnetic-inductive flow meters manufactured
by Heinrichs Messtechnik. The sensor is installed (inserted) into the pipe while the transmitter is mounted
directly on top of the sensor or separate remote, depending on the equipment design.

4.2.2 Remote installation of the transmitter
Heinrichs Messtechnik recommends this type of installation when there is little space or the medium
temperatures are high. The sensor and the transmitter are connected by a field coil and an electrode cable.
The electrode cable must be shielded and protected against disturbing interferences.
